AlexDawson 2 Posted December 3, 2011 Hi, Thank you Timmoranuk, that will be interesting to see when you have tried the twin Aquavolt 5000s. Please post here. Drew, I mostly shot stills but occasionally video. At the moment I don't have a camera, either going for the Canon 1DX or hopefully a new Nikon released before the Olympics. The way I have developed my shooting technics and work flow, strobes is not a good choose since I like to work with scene lightning and many light sources and not just illuminating the scene like most other underwater photographers do. The video posted shows a very similar way on how I like to work. So the question is, how big is the difference in power output and beam angle between the Newtlight 200 HMI and a Gates 24 VL? Or is there any other HMI out there that someone can recommend? // Alex Share this post Link to post Share on other sites
AlexDawson 2 Posted December 3, 2011 (edited) The Nuytco Newtlight has the following specs that I received from their technician. Cost $5000 Power 150 W approx Lumens 10,000 approx Burn time 35 min approx No information on beam angle. // Alex Edited December 3, 2011 by AlexDawson Share this post Link to post Share on other sites
Drew 0 Posted December 3, 2011 Alex, it's pretty easy to shoot with strobes off camera with remote triggers. The Hartenbergers have a slave sensor that is light sensitive and will fire if a strobe flash is sensed. There are quite a few threads on HMI 200W lights in the archives. Just do a search.

AlexDawson 2 Posted December 3, 2011 Hmm, no I have done strobes for 15 years and it will never be the same as continues light when you set a scene. And I am not the only one with that opinion... I like the "see what you get factor". And the flash will not work when I need to shoot video! I have looked trough all HMI threads and there is nothing useful that I can find in this forum. And nothing on Google either... But I have started contacting people that build HMI lights and other powerful lights now and are hoping to get some answers soon. Drew do you have any experience shooting WA video in green waters were all daylight disappears at 30 meters on low reflecting surfaces with good results? // Alex Share this post Link to post Share on other sites
Alexx 3 Posted December 4, 2011 Hy guys, I am also checking the market and trying to find suitable video lights to buy. I have noticed that no one has mentioned Mangrove 4L6 LED lights? Does anyone has some experience with them? How they work comparing to Gates? Share this post Link to post Share on other sites
Drew 0 Posted December 4, 2011 Well Alex, the difference is mathematically calculable but that's hard to visualize without knowing the lights. For what you want, 200+W HMI is the highest output light, but not in a small package. I know the lights in that video looked like the beam from the Halcyon 200W, which I have. It's narrow and the beam isn't even, but it's great for certain shots. You're trying to get the specs of the lights, where 200W HMI are rated at 12-15k lumens at the bulb, depending on who you ask. I'm afraid you will have to borrow/rent the lights to see if they suit your needs in terms of beam spread and light quality. Share this post Link to post Share on other sites
AlexDawson 2 Posted December 4, 2011 "Alexx" the Mangrove 4L6 LED light looks like a very good value light. There is also the Mangrove LH-VL6-40 head even a bit brighter... "Drew" I would like to know how 4000k vs 6000k light differences traveling trough green waters reflecting a rusty brown surface and then back to sensor, is it possible to calculate the reflecting light assuming the lights have same lumen? Or what is the best color temperature for green waters in your opinion? // Alex Share this post Link to post Share on other sites
r4e 24 Posted December 4, 2011 In addition to the Halcyon and Nuytco, you might also want to look at: 1) Silent Submersion Death Ray 200W HMI - switchable, used with scooter only 2) Pacific Visions Inc. PV200 - with Lithium batteries, allows two light heads in parallel The Heliumizer 200w HMI is also mentioned at some sources, but, I am not sure about availability. These are on my short list, but I have not yet taken the plunge due to recent advances in LED technology. Drew, did you once mention about perhaps testing the Edge Ultra 100/200? Any results?

AlexDawson 2 Posted December 4, 2011 Hi r4e, The ones you mention seem to be all out? 1. Deth ray seams to be discontinued 2. Pacific Vison, not possible to contact via email? Their mail bounces? 3. The Heliumizer I have been contacting for years without any success... 4. Salvo got sued just as they were introducing their first HMI 5. Halcyon I have not contacted yet, they have a 200w HMI Apollo video light. 6. Sartek has a 150watt HID that seems ok but not sure if it is powerful enough? 7. OMD 200w DCU. I am waiting for a reply on delivery and price 8. Genisea light 200w I don't know about. 9. Nuytco has discontinued their NEWTLITE 200W for a 150w model. Thats all I know of and most of them are only available in the second hand market. Share this post Link to post Share on other sites
r4e 24 Posted December 4, 2011 The ones you mention seem to be all out?1. Deth ray seams to be discontinued 2. Pacific Vison, not possible to contact via email? Their mail bounces? 3. The Heliumizer I have been contacting for years without any success... 4. Salvo got sued just as they were introducing their first HMI ... To some extent I agree, seems to be even worse than when I collected my list. 1. For Death Ray, you might want to see if any dealer has something in stock, atleast the following web page claims so today: http://www.dolphinscuba.com/ProductDetails...a_7cDP_DEATHRAY 2. Did you check for a typo? I got a bounce for sales@pacificvisionsinc.com, but, info@pacificvisionsinc.com was ok. 3. Heliumizer is (was?) a side-time business for the person involded. 4. I guess the folks of Salvo are continuing atleast some part of the business as Light Monkey. However, I remember additionally hearing comments that they had difficulty in getting access to some of the (original) HMI lamp components and that the newer replacement components were less reliable. The component reliability issues might just be a rumour, but, it made me very cautious about the technology over all, especially with the very limited supply worldwide. Whoever knows better, please correct us. Share this post Link to post Share on other sites
AlexDawson 2 Posted December 4, 2011 (edited) Ok, I will email Dolphinscuba about the death ray but it is not rely what i want since you need a scooter... I tried both emails now and they both bounce? I have a friend who is building a HMI now and he might have it ready before christmas. Lets see how that goes..? // Alex Edited December 4, 2011 by AlexDawson Share this post Link to post Share on other sites
r4e 24 Posted December 5, 2011 I tried both emails now and they both bounce? Relating to my inquiry yesterday (Sunday) to info@pacificvisionsinc.com, I just got a friendly response from Louis Prezelin. The 200W HMI lamps are not for sale (anymore). However, they are available for rent and/or long term lease, and, I got a quote. Alex, seems that either you or Pacific Visions Inc. have email compatibility or spam filtering issues. If leasing is a viable option for you, you might try contacting them via an alternative email address or per phone. Share this post Link to post Share on other sites

peterbkk 110 Posted December 7, 2011 I find that the color temperature of the Sola 4000s balances very nicely with ambient lighting in clear blue tropical water. Regards Peter Share this post Link to post Share on other sites
AlexDawson 2 Posted December 7, 2011 What's the point? You can change it all in post. Drew, maybe you misunderstood me or I have misunderstood everything about how different wave lengths travel differently trough water? Re: r4e I am not interested in renting lights and I guess that their spam filter doesn't like my email address? My friend just got a hold of some brand new polish HID with 220w power that is supposed to be very good. Hope to see it in action during next weekend..? // Alex Share this post Link to post Share on other sites

Regards Peter Thank you Peter, I will keep this in mind for my choice. Do you find them bulky and how is the drag in the water? // Alex Share this post Link to post Share on other sites
peterbkk 110 Posted December 8, 2011 Thank you Peter, I will keep this in mind for my choice. Do you find them bulky and how is the drag in the water? // Alex I switched from 3 x Sola 1200s to 2 x Sola 4000s. The bulk / drag is not much different. They are bigger but don't effect the balance underwater. Regards Peter Share this post Link to post Share on other sites

peterbkk 110 Posted December 11, 2011 Do you have any sample footage of the sola 4000s? Watch this video: http://vimeo.com/33075140 The Sola 4000 was used on every dive, except the footage of the Leopard Shark, which was from an earlier trip. I used them balanced with ambient light at 1:12 with the anemone fish and immediately following with the glass fish. Both the seahorse and ghost pipefish was lit by the Sola as they were about 30 meters deep. For the ambient-balanced shots, the power setting would be from half to full, spending on the ambient brightness. Some night dive footage of an octopus is at 4:35. Power was set to half.

r4e 24 Posted December 13, 2011 I found a polish company specialized in diving gear and lights. Their website is in polish, but, the tech specs are understandable, and for us in Northern Europe, the company is much closer to visit than the other HMI lamp manufacturers. They produce the following amongst others: - 140W LED video lamp with Goodman handle, 5500K, 10000 lumens, rated to 150 meters depth - 200W HMI video lamp, 5600K, 16000 lumens, 150 meters depth - 1200W surface supplied (230 V AC) HMI video lamp, 5600K http://www.gralmarine.com Share this post Link to post Share on other sites
AlexDawson 2 Posted December 13, 2011 Thanks for that r4e! I will ask my friend Tomek Strachura at Santi if he knows of this brand. He has very good knowledge about the diving community in Poland. I will post here if he has any good info on the lights. // Alex Share this post Link to post Share on other sites
Davide DB 482 Posted December 17, 2011 Hi Alex, I've just taken delivery of two Fisheye Aquavolt 5000s and very impressive they are. I've only charged them and turned them on topside, however the beam looks very wide, clean and and consistent. Tomorrow I hope to take them to depth. Hi Tim, Didi you tested the aqua 5000? Have you something to show? Nobody have the Sola 2000? I've seen them at the shop here in Italy... Share this post Link to post Share on other sites
