Surfing the net, I found these monster lights the wasp.
I know they are expensive, but some specs look great.

The web site doesn't specify the burn time at different power settings.

Any thoughts about it?

Considering the price and unconventional form factor, it would be interesting if they could provide Wetpixel with a sample for objective review and possible comparison with other high powered lamps like the Sartek LED. See these LED lamps in e.g. Secrets of the Yucatan, Episode Two

There is a short film on their site showing some footage. 170 beam and 18,000 lumens. I can't tell whether there is a control for the power output or not. Yes, pretty costly but it appears that you might need only one so, for a total price, that might not be too bad.

Amazing video!!!

The detail with the Sartek light is that is just a powerful light head, but you need a canister to make it work, and I doubt you will have different power settings with it.

The main issue with that light i think would be, being stuck in the one spot. It would be great for doing wide angle on a wreck or reef scene but when shooting macro or trying to put the camera in a hole you really need lights that are flexible.
They look impressive though.
Cheers Pete.

I think this light would be good for survey work, ROV-mounting etc., and where you just need lots of light no matter what, such as in a big cave in clear water. If used on its own you're going to get strong shadows. It also looks too big to effectively mount on a normal light arm, and if it's mounted close to the lens there's a high chance of backscatter. I'd be interested to see how the manufacturer recommends mounting it.

Agreed Nick..this is the same film that is on their website. There appearance and size is what led me to say that it appeared that only one of them might be necessary. It looks heavy.

This is a local company for us and we have had a chance to see this unit as it has gone through development. You have 100% control over power with a very nice full color OLED display showing power output and battery life (if I recall). Feels very solidly built and it is about 1/2 the size of your typical Gates consumer cam housing. It is too big to put on one strobe arm. For display on dry land we set it up with one metal strobe arm running from each Gates handle to a triple clamp on the bottom of the WASP housing. Longer versions of this would work underwater.

Want to get one underwater but they have sold all the first round of production. As mentioned at full power I think the trick would be for a single shooter getting the light far enough from the housing to avoid backscatter as the first versions had a 180degree beam angle*. It would be perfect for wreck or wide angle work with a second diver in control of the light. They have several very interesting modifications in the works but I will drop a note to the engineer and see if he wants to answer questions. I do know they are making a smaller unit in the 2000-3500 range, in a cube type form, think Borg for you Star Trek fans.

Could be interesting additions to the plethora of lighting out there.

*My memory is maybe off on some specs

It certainly an interesting and innovative design - looks like walli or Number5. I'm quite interested in this design as I'm in the middle of a custom build with a 20,000 lumen spec (on paper) for my own purposes (a particular cave project).

One of my design briefs was to ensure the light would have both throw and width, and that the throw and width light output could be independently controlled. My intended purpose is a big ass light to be carried by a model, and/or mounted to a dpv well off the camera. Currently I've found bare LEDs to have a seriously limiting throw, but on the positive side they have a great matte beam output.

My guess is that in any other than real clear water, the flare from this light will be a killer. The 160 degree in water beam width is impressive though. The most I can seem to get out of a flat lens is about 100-120, so am considering a dome but this is what impractical in a tec/cave diving environment (namely the dome will get trashed without a shade).

On my recent trip to West Papua I was field testing a new compact "proof-of-concept" LED light which uses a 100w multi- emitter array and pumps out 9000 Lumens, 5500 kelvin @ 130 degrees for 65 minutes on full power (also switchable to 4500 and 2000 Lumens for very long burn time). I cherry picked the Chromaticity BIN so the CRI and tint is very nice on GH2 video.

It's quite compact and lightweight (1.6 kg) machined aircraft grade aluminium. Two in tandem (18,000 Lumens) really lit up the scene during the night dives with the whale sharks or on the walls at dusk. Truely an amazing experience night diving with so much light! Sometimes it was too much for some animals and the dimmer came in handy.

The advantage of two, I found, is redundancy, flexibility (both configured together or each on separate sides of the camera) and adjustable beam angle (for really wide coverage particularly as an off-camera model light).

I've only made a few of these for myself and some professional videographers for evaluation. I'll have a video up on Vimeo soon showing what these lights can do.

For comparison, here is a wreck video in not-so-clear water. A single 200W HMI lamp was used for illumination. 16,000 lumens. With our murky waters, it was a bit difficult to get a backlit profile of a 70 meter ship, or even the rear section of it. There was hardly any problem with flare/backscatter as long as the lamp was not too close to the camera.

Here's a couple of photos. The first shows the size relative to the current production LED 4000. The LED 9000 is about 300g heavier because of it's all aluminium construction and bigger battery. Both are tested to 100m. In both units the head unscrews to allow quick battery swap and/or charging.

The second photo shows the handle removed and fitted to the Nauticam GH2. In real-world use there would be a reasonably long arm (I use the floaty type) between it and the housing.

There is an attachment point at the rear to allow two lights to be easily coupled together (with a special bracket) for 18,000 Lumens.

The one hour burn time @ 9000 Lumens is due to a state-of-the-art 5 AH Lithium battery. My aversion to Lithium batteries is mellowing after using this design which has sophisticated protection circuitry built in...and has behaved very well so far. Posted Image

9000 lumens..... they pack a punch. 5500K and 65 mins on full power. Great specs, what is the cost going to be?

Hi Jon.

Not sure yet...things are moving faster than I had anticipated. Everything I design and build is primarily for myself and a few working pro dive buddies to use so I'm forever improving things before finalizing the design. But I've approached the work on the LED 9000 differently and outsourced the machining and battery design to competent suppliers (ha ha...helps to have a brother-in-law with factories and a manufacturing network in China). I also personally select all material and electronic components so it takes a bit of time to set up a production workflow. I guesstimate it would be selling for around $1500 in Australia


So far the light has exceeded my performance and reliability expectations...even under tough "4 dives a day and recharge from an island generator at night" conditions. Also, I've finally found a 100w emitter array that is suitable for critical color work (there's many out there but most have very poor chromaticity).

I've always mistrusted Lithium batteries (from a safety perspective) but they do certainly offer burn-time advantages. However, if sourced from the best manufacturers (made with BiCMOS Protection IC's) and well maintained even I am slowly becoming a Lithium convert. I'll wait until my next trip in August and until I get more feedback from several other selected users (so far so good) before I make a decision about selling these lights...Posted Image

Woops...sorry Andres. I didn't intend to hijack your thread :(

Just wanted to let you know that a well specified 9000/18000 Lumen light is no big deal with current tech. I suspect there will be many around to chose from very soon. :)

Speaking about monsters, there is also this Sartek led light head rated 10000 lumen, very expensive indeed:

I've seen a couple of cave videos where the model was using this head:
