Aditech Mangrove VC-4L6 Underwater LED Video Lights (or handheld dive light)

14 August 2014 - 12:54 PM

Two mangrove light sets, 2 lights, 2 chargers and 2 spare batteries (one spare battery doesn't work but can be rebuilt for half the price of a new spare battery)
The lights are intended as video lights primarily but also comes with a handle so they can be used as handheld dive lights.

 

$700 plus actual shipping for the lot. (only shipping in the US)

They are very powerful at 4320 lumens.
They are LEDs so there is no bulb to burn out.

Info from the website:

Mangrove´s new line of LED lights are an industry breakthrough. The VC-4L6 specially designed for underwater video and photo is supplied with one Solid-State LED module array emitting a staggering 4320 lumens each!

Featuring two output levels, the 40W light can dim from high to medium power output levels allowing you to dim lighting for a quick exposure adjustment.

The VC-4L6 offers daylight color temperature, a 16:9 illumination pattern (approx. 110° reflected beam angle) and output about the same as a  130 W halogen light.

All of this in a self contained package with relatively low heat generation, low power consumption, and amazingly long burn time make the VC-4L6 the ideal small high performance video light system.
