Comments about I-Torch Video Pro5 1600 Lumens LED Light:

Great video light - very powerful, easily illuminates stuff up to about 3-4 feet in deep water. Nice broad beam. Lasts 60 minute dive on one set of fully charged batteries. Didn't need to use flash for close-up photos either. Only drawback is very powerful "white" light, so washes out colours/overexposes if too close (macro stuff). So just have to watch out (or use the lower intensity setting). Expensive but if you like video, worth it. Heavy for it's size but no choice due to heavy batteries and very robust case.

It looks very well build and comes with everything you need for a video lamp: Extra batteries, charger, arm attatchment. Light is quite bright and white.
I have not tried in the water yet but in land the light is impressive.
The only problem that I found is changing the intensity of the light:
It is hard to tell if you are on high on low, no indicator. It needs a dimmer as it is hard to change or tell if you are at full or at 40% which are the only two alternatives.
