I. INTRODUCTION

UW strobe quality and power have improved dramatically in the years since the popular Underwater Strobe Finder appeared here in 2004 (1), but unfortunately it is no longer accessible. Since then new UW strobes have appeared, others have retired and problems with some have surfaced. Previous excellent reviews (2), containing much still useful information, also have been overtaken by the loss of some strobes and the rapid improvements in strobe technology.

Strobe Warranty: As strobes are known to fail, often within their first year, it is wise to have a Strobe Warranty:  Some manufacturers warrant their strobe against defects, and service other problems for one year from date of purchase, many do not. Be aware that the warranty often is only valid if the strobe was purchased from a dealer licensed by the manufacturer. One can find if a dealer sells strobes under warranty via the internet. For example, to the query “Inon strobe dealer locator”, the reply was:

Inon Customer Support [World Network] www.inon.jp>customer.network. 

 For Sealife it was: “https://www.sealife-cameras.com > dealer locator.” One proceeds from there.  

For easy access the strobes are listed alphabetically, first in Part II as a Short Strobe List, followed in Part III by a more complete list of Strobe Specifications and Details.

To maintain the Finder’s usefulness, I hope the kind reader will take the time to post additions, corrections and developments.

III. STROBE SPECIFICATIONS AND DETAILS, LONG LIST

Some strobe makers provide a wealth of information, others very little. All details and claims are the manufacturers, the prospective buyer need take them with a grain of salt.

 

HARTENBERGER, 3 strobe models with sync cord and built-in battery: Model b125 eu 1,298.  b250 eu 1,598. b625 eu 1,998

Conception with know how:

Over 30 years of experience in underwater technology have gone into Hartenberger underwater strobes. Our concept for underwater strobes has led the industry for years.

A combination of proven traditional, and modern digital High Tech electronics have gone into our product development making them milestones in the industry for underwater strobe technology.

All the important components of our strobes such as the reflector, pilot light, cell packs and synchronisation cables have been developed as “plug-in” modular units. This allows numerous possibilities for technical details, functionalism and esthetical appearance.

Relying on our years of experience in manufacturing underwater strobes, enables us to give a 5 year guarantee against manufacturers defects on all the Aluminium, Plastic and Stainless Steel components. There is a 2 year guarantee on the electronics of the strobes.

Housing: A centre piece of our strobes is the specially constructed Housing, with tried and tested applications over the years. The individual parts are turned on CNC lathes using marine aluminium alloy.

To provide the best surface treatment, the entire housing is coated with AHC (Aluminium Hard Coating). This results in a surface with much more chemical and abrasion resistance than a standard anodised finish. The chemical resistance of the AHC coating is even better than stainless steel and can be found in various industrial and military applications.

Despite the fact that the front and rear housing covers can be opened without tools, the sealing is provided by special compression and axial O Rings. We only use high quality Viton O- Rings.

The mounting point on the lower side of the strobe allows a multitude of mounts to be used (M6, M8 and M10 Threads).

The switches have double O Ring seals and provide years of reliable, trouble free use.

Ergonomics

Due to the ergonomically positioned switches on the side of the strobe, the settings can be easily monitored and/or adjusted without any difficulties and your camera and strobe position underwater remains undisturbed when reaching for the switches in setting up your shots. 

Electronics

Choosing modern and over-dimensional components in combination with tested micro-processor electronics results in one of the most powerful and fastest recycling underwater strobes in the world.

The core of the Hartenberger strobes is the powerful and robust transformer. This allows a power rating of 625 watt/seconds and a recycle time at full power setting of 0,8 seconds !! (see technical specifications). The recycle time using lower power settings allows more than 10 frames per second (vital for fast motor drive use).

After recharging the condensers, the transformer switches off automatically. This reduces cell use and also avoids the prolonged radiation caused by the charging which disturbs some underwater life, causing them to flee.

The strobe ready signal appears on the switch panel of the strobe and in the viewfinder of the camera and easily visible. At the same time, a short acoustical signal (beep) can be heard.

The camera shutter speed is automatically set according to the synchronization.

A special technical feature of our strobes is the extremely short flash duration hereditary in ring formed strobe tubes.

This is necessary because some Nikon cameras (i.e. F5, F100, F90...) require the entire light for a correctly exposed picture within 1/500th of a second.

Should the strobe require longer than this to achieve the correct exposure, then the camera will not send out the TTL cut off signal to the strobe!!!

In this case, the remaining energy is released as light and results in an uncontrolled, overexposed picture. 

Mode-Settings

The right switch sets the following modes

·       OFF

·       ON without pilot light

·       ON with 100 % pilot light

·       ON with 50 % pilot light

·       ON with 25 % pilot light

·       Slave sensor with 100% pilot light

·       Slave sensor without Pilot light

·       Automatic Signal (for attention)

In this positions, the following signals are possible and generated automatically:

1. Pilot light with International SOS signal (3 x short, 3 x long, 3 x short)

2. Strobe light with SOS signal (3 x short, 3 x long, 3 x short)

3. Continuous Strobe every 15/30/60 Seconds at Full, -1 and -2 power settings

The strobe can be used as a slave unit (strobe will be activated by a primary strobe) either with or without the pilot light.

The slave sensor is not sensitive to natural daylight, but reacts very sensitively to the sharp light impulses from strobes. This allows the strobe to be used underwater at long distances from the primary strobe.

The 6 manual power settings are available for the slave mode.

A special feature is the TTL slave mode. In this mode, the amount of light which the slave produces is remotely controlled by and matched to the primary strobe!

Power-Settings

Tue following modes can be set with the left switch:

·       TTL-Mode (automatic exposure control from the camera).

·       6 Manual Power settings each of 1 f-stop.

The automatic TTL control is available for almost all types of camera and is built in as standard for the following makes of camera: Pentax, Canon EOS, NIKON F5/F4/F100/F, NIKONOS V and NIKONOS RS.

The electronics automatically recognises the type of TTL control from the connected camera.

Should there be an underexposure in TTL mode, an acoustical alarm will sound. A warning will also appear optically in the following forms: blinking ready light in the viewfinder, blinking pilot light and blinking red light on the switch panel on the side of the strobe. 

Pilot-light

The dimmable pilot light allows the user to adapt the strength of the pilot light to the ambient conditions. At reduced settings, energy is saved and the burn time is proportionally increased.

Special version without surcharge:

The pilot light can be controlled from the camera housing. This feature simply requires the appropriate switch on the camera housing.

The same switch can be used to trigger the strobe test mode. When this is activated, the strobe releases approx. 40 weak flashes within 2 seconds. This allows the photographer to judge the flood of light and establish any areas of shadow.

The beam of the pilot light is spot formed with a strong concentration in the middle point and a soft illumination of the surrounding areas. (This reduces the tunnel vision effect during night dives).

The pilot light is a plug in unit and is user replaceable.

The standard 6 V high temperature halogen Bulb is available rated at either 10 or 20 watts.

Reflectors

The plug in reflector unit with 95° beam as standard can be replaced within seconds (250/625 TTL).

A different colour temperature can be achieved by replacing the reflector. Reflectors are available with the following (approx.) colours.. 5500, 5000(standard), 4500 and 4000 Kelvin.

The crystal clear dome port can be replaced with a matt dome port. The matt port diffuses the light and generates a softer light from the strobe. The effect on the power output of the strobe is hardly noticeable.(approx-0.5/-1). 

Alarms

If by mistake you try and take a picture without first switching on the strobe, an optical and acoustical warning will get your attention.

A discharge protection prevents the cells from an uncontrolled discharge. This is indicated by an optical and acoustical alarm.

The transformer is deactivated when the cells are nearly empty, it can however be activated manually for 3-5 more additional frames.

For safety reasons (ascent), the pilot light remains functional for a few minutes.

Should water enter the housing there is a sensor which immediately detects the smallest amount of moisture. For safety reasons, the condenser is immediately discharged (automatically generating a flash). After this discharge, the pilot light and all red LED lights will blink permanently and an acoustical alarm will sound. 

Cell-packs

To remove the standard cell pack (Nickel-Cadmium) for charging, first unscrew the rear cover. The complete plug-in cell pack can then be removed or replaced with a charged pack within seconds.

The electronics are separated from the cell pack housing by O-Ring seals, this prevents moisture that has entered the cell pack housing from entering the strobe’s electronics. 

Synchronisation-Cable

The supplied standard synchronisation cable with the NIKONOS-V plug can be removed from the strobe allowing the slave mode without a cable dangling from the housing. This also means that a defective cable (expendable component) can be user replaced without sending the strobe to an authorized repair workshop.

A special feature first developed by us is the double seal NIKONOS Plug. The innovative positioning of the second O Ring provides 100% more safety and security in sealing. The plug’s thread is also kept dry whereas the original plug’s thread is surrounded by water. This prevents the vacuum which is generated when removing the plug, thus sucking water into the socket. Corrosion of the threads is also avoided.

Ikelite DS51

MSRP: US$450

The Ikelite DS-51 Substrobe replaces the DS50, which has been a favorite of underwater photographers the world over. In addition to incorporating all the same great features of the DS-50, the DS-51 provides a Manual Exposure Mode with six (6) manual power settings in one-half f-stop increments for precise illumination of subjects underwater.The compact, lightweight and affordable Ikelite DS51 Substrobe is an excellent choice for many underwater photographers. Its digital electronics make it fully compatible with digital cameras as well as traditional film cameras such as the Nikonos. The strobe can easily switch between TTL/Auto and any of the six (6) manual power settings for complete control over lighting the subject. The DS51’s intensity and angle of coverage make it equally suited for macro and general photography. The strobe’s wide-angle diffuser increases the angle-of-coverage up to 80 degrees, softens the light and helps to reduce backscatter. The DS-51 Substrobe’s power rivals strobes twice its size, recycles in a quick 3.5 seconds, and provides 200+ flashes on a set of batteries. Much shorter recycle times and more flashes per set of batteries can be realized during TTL/Auto operation.

When connected with a sync cord to compatible Ikelite housings, or the Nikonos camera system, the DS51 Substrobe offers TTL/Auto and Manual Mode. When used with other manufacturers housings, the DS51 Substrobe can only be used in the Manual Mode utilizing the six (6) power settings.

The DS51 is compatible with the Ikelite DS Sensor and EV-Controller. When used with the EV-Controller, the DS51 Mode switch is set to the TTL/Auto setting and the EV-Controller then provides ten (10) power settings in half-stop increments.

Ikelite DS160

MSRP: US$799

The DS160 series strobes are specifically designed for underwater use to provide the most colorful and natural wide angle lighting on the market.  A professional grade round xenon flash tube and powder coated reflector produce perfectly a soft, stunningly warm 4800K light.

Optional accessories for corded, fiber optic, or remote triggering.

The built-in modeling light automatically turns off and back on when taking a still photo to avoid over exposure.

Our famous quick-release toggle system attaches the battery pack with ease and confidence.  A high capacity rechargeable NiMH battery pack provides longevity and rapid firing that no set of AA batteries can provide.

When combined with a compatible TTL system, the DS160 automatically adjusts brightness to provide perfect exposure whether you’re shooting macro, portrait or wide angle.  Focus on your camera settings and composition and enjoy the increased number of flashes and even faster recycle time you’ll get when working with a TTL system.

RECYCLE TIME + BATTERY LIFE NiMH batteries are work horses, and a great choice for high powered rechargeable devices due to their performance and reliability at a more affordable price point than lithium ion.  This high capacity battery pack provides professional quality power and speed flash after flash, well beyond the capabilities of even the best AA-cell batteries.

Shooting full power flashes?  Expect a lightning fast 1.6 second recycle time and over 225 flashes on a single charge.  Shooting TTL or in a fractional power setting? You’ll get very close to instantaneous recycle time and up to 3X as many flashes... plenty for a day of diving!  This battery recharges in half the time of its Li-Ion counterpart for quick topping off before your night dive.

Our famous quick-release toggle system attaches the battery pack with ease and confidence, making a flooded battery virtually impossible. 

SMART CHARGING.  The included Smart Charger for NiMH accepts variable voltage in the 100-240V range.  Smart charging provides safety and helps to increase the lifetime of the pack by switching over to a trickle charge when the battery pack is fully recharged.  Feedback on charging cycle is indicated by an LED on the front of the charger.

This charger is compatible with NiMH battery packs only.  (Chargers designed for NiMH or NiCad batteries cannot be used with Li-Ion technology.)

Ikelite DS161

MSRP: US$949

PRODUCT DETAILS

The DS161 combines power with wide angle coverage to give you the most bang for your buck.

The quality of light is exceptional due to a round flash tube and custom powder coated reflector designed specifically to deliver the softest, most even coverage possible.  Strobes with a straight flashtube may be capable of high powers, but require the addition of a diffuser to spread out their sharp, rectangular beam pattern and reduce the harsh hot spot.  The DS160 beam is designed to be perfectly soft and wide spread through its reflector design, and is capable of providing you the coverage and power you want and avoiding the one f/stop loss caused by adding a diffuser.

Both our DS160 and DS161 strobes are legendary for their ability to keep up in rapid firing situations—a cut above any flash on the market.  Electrical sync connection and a high-capacity battery pack provide the speed you need to capture fast moving subjects like sharks and sailfish at just the right millisecond.

When combined with a compatible TTL system, the DS161 automatically adjusts brightness to provide perfect exposure whether you’re shooting macro, portrait or wide angle.  Focus on your camera settings and composition and enjoy the increased number of flashes and even faster recycle time you’ll get when working with a TTL system.

BUILT-IN VIDEO LIGHT

Instead of a simple aiming light, the DS161 includes a super even, 500 lumen video light. The light is suitable for close-up, macro, portrait, and wide angle fill-in work or as a focus assist light. Output is adjustable in 10 brightness settings plus an SOS mode for emergency situations. Automatic shut-off when the flash fires ensures that the video light will have no undesired effects on still photos.

NiMH batteries are work horses, and a great choice for high powered rechargeable devices due to their performance and reliability at a more affordable price point than lithium ion.  This high capacity battery pack provides professional quality power and speed flash after flash, well beyond the capabilities of even the best AA-cell batteries.

Shooting full power flashes?  Expect a lightning fast 1.6 second recycle time and over 225 flashes on a single charge.  Shooting TTL or in a fractional power setting? You’ll get very close to instantaneous recycle time and up to 3X as many flashes... plenty for a day of diving!  This battery recharges in half the time of its Li-Ion counterpart for quick topping off before your night dive.

Our famous quick-release toggle system attaches the battery pack with ease and confidence, making a flooded battery virtually impossible. 

SMART CHARGING

The included Smart Charger for NiMH accepts variable voltage in the 100-240V range.  Smart charging provides safety and helps to increase the lifetime of the pack by switching over to a trickle charge when the battery pack is fully recharged.  Feedback on charging cycle is indicated by an LED on the front of the charger.

This charger is compatible with NiMH battery packs only.  (Chargers designed for NiMH or NiCad batteries cannot be used with Li-Ion technology.)

Inon Z-240 Underwater Strobe (Type 4)

Discontinued, often available on eBay and Wetpixel.US$500,

Sync cord and Fiberoptic cable, 4AA batts

Discontinued as of July 2017 and replaced with the Z-330

Still popular, much in demand in the used strobe market, $300 and over.

Circular even beam thanks to dual flash bulbs.  Built-in focus light.

 

Features:

High power with Guide Number 24, wide 100 degrees circular beam angle  light distribution even without a diffuser

INON unique T-shape Twin Flash construction and optimally designed reflecting mirror/prism enable effective light distribution and produce powerful guide number 24 (*1) at wide circular 100_ beam coverage without a diffuser from compact body (outer diameter:99mm x depth: 100mm x height: 122mm) (*2) run by only 4 x AA batteries. Even for shooting wide subject, the Z-240 delivers strong strobe light to an entire area without using a diffuser which suppresses strobe power. Packaged -0.5 White Diffuser 2 (TTL/Manual) increases bean angle to 110 degree (guide number 21). With the white diffuser, color temperature of the Z-240 decreases at 100K (Kelvin) only to depict underwater scenery in same color regardless of using the diffuser or not.

(*1) Measurement in air/ ISO100m, Nominal value

Minimum recycle time 1.6 seconds. Minimum recycle time at full flash (how fast the strobe is ready to fire just after full flash) is approx. 1.6 sec.(*3). The Z-240 unique circuit components carries two sets of fundamental electrical parts (transformer and transistor) to achieve fast recycle time.

Optical connection/electrical connection, digital/film fully compatible

The Z-240 offers all advanced features including S-TTL Auto mode which supports TTL Auto exposure control by transmitting built-in flash light to an external strobe and compatibility with Clear Photo System. Optical connection system widely supports from transparent housing for compact digital cameras to a housing for digital SLRs with built-in flash regardless of make or model. Its sync connector accepts Nikonos 5 pin type cable to shoot in TTL Auto mode with a film camera or in Manual/External Auto mode with high end digital SLR not equipped with the built-in flash (*4).

(*4) Usable function may vary depending on camera system and connection method

EV. Controller to adjust exposure of S-TTL Auto

It is simple to fine-tune flash power in S-TTL Auto by dialing the EV Control Switch on the back control panel. Adjustable range is 3 steps to increase and 6 steps to decrease, to suit to personal preference or different exposure control characteristics among camera models.

Next generation wireless TTL

The Z-240 Type 4 successfully amplifies receiving optical signal from the slave sensor 20 times more comparing to previous Z-240 Type 3 to provide wireless S-TTL Auto mode using a mirror instead of an optical cable. Attaching optional Wireless Connection Kit on the Z-240 Type 4 and combined with a housing via Shoe Base Set or Grip Base D4 Set creates a handy S-TTL Auto shooting set.

13 step Manual / 24 step External Auto Intensity settings

The Z-240 supports professional needs for sophisticated and precise lighting by its 13 step Manual mode with 1/2EV. increments and by semi-automatic 24 step External Auto mode with 1/4EV. increments which determines strobe output based on onboard sensor. INON unique Advanced Cancel Circuit benefits you with faster recycle time and more images per battery set to eliminate drawbacks when using with a pre-flash type digital camera where the built-in flash always burst full dump.

      High-intensity 180 lumen p

Focus Light with shutter linked auto OFF function

Multifunctional Focus Light for supporting focusing as well as for using as an indicator of strobe charge status since it turns on in synch with strobe’s ready LED lamp. The Z-240 Type 4 uses high-intensity 180 lumen power LED as Focus Light which is also usable as an independent diving light producing 180 lumen/20_ coverage. The Focus Light automatically turns OFF in synch with shutter release where it quenches emitting light at the time of pre-flash under Optical D Cable Connection with a pre-flash type digital camera, so it is never recorded in an image (*5).

(*5)Focus Light may be recorded on an image depending on camera system, connection method and shooting condition.

Integral pre-flash mode detecting function

Fully compatible with a camera like Nikon digital SLR cameras D700/D300/D200/D90/D80 which alter number of pre-flash between once or twice depending on shooting condition making total flashes twice to three times. The Z-240 automatically identifies number of pre-flash to activate adequate program to support proper functioning of External Auto, Manual as well as precise S-TTL Auto mode.

Manual + TTL Auto mode for film cameras

Newly introduced flash mode for hard wired film camera to pre-set maximum flash power in TTL Auto exposure to compensate the weakness of the TTL Auto mode. Conventional TTL Auto may not get along with a particular situation like shooting a swimming fish without colorful back ground where TTL Auto could deliver full damp resulting from TTL error. The Manual + TTL Auto mode can avoid this problem by manually setting necessary flash output for a subject to stop firing at pre-set flash amount in case of TTL error happens and benefit you to drastically reduce overexposed images.

iDive SYMBIOSIS SS2R Underwater Strobe & Video Light  $599.

This complete Underwater Lighting System (patent pending) is designed by iDiveSite (previously known as iTorch) for underwater photography and videography. It offers user upgradable LED head and battery pack. It now includes a 4,000 lumens video light.  

The name Symbiosis means interaction between two different organisms living in close physical association, typically to the advantage of both. With this, video light and strobe are now in one body.  They could work at the same time or separately. Video light could be upgraded by purchasing just the LED head in order to have an up-to-date video light. Photographers can build on demand, they can purchase different kinds of modules to suit their needs.  

Symbiosis SS-2R Features

·       Easy mounting for any underwater housing. The SS-2 strobe includes both a YS mount and a 1” ball mount allowing you to mount on both flex arms and standard ball and clamp arms. Keep in mind the strobe may be too heavy for most flex arm systems, so we recommend using ball and clamp arms.

·       Universal Fiber Optic Cable Mount. The SS-2 uses the Sea & Sea style plug in fiber optic cable which is fairly universal across most housing brands.

·       Intuitive TTL Training Mode. Never worry if the strobe will match the camera flash again. The SS-2 includes a TTL Training Mode which learns the output of your camera flash and allows you quickly sync the strobe and your camera regardless of how the camera pre-flashes.

·       Long Battery Life. The SS-2 includes a high capacity battery which allows for up to 550 flashes or 100 minutes burn time with the video light on full power. When using a mix of strobe and video light the total life will be a combination of the two.

·       Quick to Recycle; never wait long for your next shot. With a recycle time of 2 seconds from full dump, the SS-2 is a fast recycling strobe

SEA&SEA STROBES

Three models are available: The YS-01 and YS-03 compacts and YS-D2J standard size, plus two good discontinued models, the YS D100a and YS-D250; the other models are obsolete.

SEA&SEA YS-01 Strobe  $430  

Features a circular beam angle of 100 degrees x 100 degrees and a guide number of up to 20. The YS-01 is a new compact-type slave strobe that can be used for all applications from wide-angle to macro photography. 

You can switch between DS-TTL (Digital Slave TTL) and a ten-level manual control function, to enable fine adjustment of the light level. You can also set up a lighting system that uses two strobes in DS-TTL mode. Power comes from four AA batteries for a powerful and long-lasting strobe. You can enjoy taking pictures all day long without having to recharge the batteries. The recycle time takes 1.9 seconds with nickel-metal hydride batteries (2700 mAh) for stress-free continuous shooting. Fiberoptic cable.

The YS-01 is furnished with a high-luminance white LED target light (1W) indicating the optical axis of the strobe attached to its front face that is effective for night diving. You can fully exercise your creativity with the YS-01, which can be used as a primary strobe or secondary strobe in a wide range of applications, from compact digital cameras to digital SLR cameras.

Sea & Sea YS-D2J Underwater DS-TTL Strobe
Updated version of the YS-D2 – Made in Japan. Flash Tube Overheating has been fixed.  US$600 to $690. Has replaced the YS-D1 as the most popular UW strobe for DSLR users. Excellent night-time visibility. The illuminated control panel is ideal for night diving. 
The color of the panel illumination changes to indicate mode: aqua blue (in DS-TTL mode), blue (in slave TTL mode), orange (in manual pre-flash mode) and Green (in manual mode without pre-flash). You can check which mode the strobe is set even under pitch-black conditions. 
The maximum guide number is a powerful 32 (ISO 100, meter). Recycle time is only 1.5 sec

The YS-D2 is powerful enough to illuminate a wide area, even under very bright conditions with plenty of natural sunlight. During macro photography, where subtle exposure control is required, manual mode can easily be selected and the guide number quickly adjusted as low as 1.

DS-TTL ll automatic exposure control with improved accuracy and stability. 
SEA&SEA’s own automatic exposure control system, DS-TTL ll, has been further improved. Tuning light emitting timing in detail and adding light emission detection function, the accuracy of automatic TTL exposure has been noticeably improved. Previously, TTL photography was difficult with the lens’s aperture wide-open (maximum aperture) and images were likely to be overexposed. It is now possible to give a low powered flash so the correct exposure can be easily achieved with the YS-D2.

EV control function can finely tune the amount of light emitted. By controlling the actual flash light level, the strobe achieves accurate exposure compensation with EV compensation. As the exposure compensation range has improved to +/- 2.0 EV, users can concentrate on shooting even more creative images. (-2,0EV, -1.5EV, -1EV, -0.7EV, -0.3EV, +0.3EV, +0.7EV, +1EV, +1.5EV, +2.0EV).

Two diffusers and red filters included with the strobe as standard. By attaching one of the included diffusers, the beam angle is increased to 100° or 120° (circular) with a soft and even light. The red target light filter helps avoid disturbing skittish creatures that are likely to react to normal light. The red filter is fitted inside the diffusers.

The target light can be adjusted in 2 steps. The strobe is equipped with a target light (approximately 100/300 lumen). In use (target light switch in ON position), the light will be automatically turn off when the strobe fires and will automatically turn back ON after 0.5 sec.

Handling is greatly improved. Larger knobs and a new magnetic rotary switch help prevent controls being accidentally reset in use. With the new controls, quick operation is possible when photo opportunities suddenly appear. Custom mode is a new innovation which allows the YS-D2 to be compatible with cameras with non-standard pre-flash settings. The YS-D2 can be set to be compatible with cameras with non-standard pre-flash in DS-TTLII and manual modes.
