The Lumen Subsea Light is a blindingly bright LED light for use on ROVs, AUVs, and other subsea applications. We designed this light specifically for this purpose and it has a few neat features:
Fully dimmable control using a PWM servo signal (1100-1900 μs)
Simple on/off control with no signal needed
Daisy-chainable to connect multiple lights from a single connection
Automatic, smart over-temperature compensation for maximum light output and safety in air
New in R2: Built-in mounting holes on the side of the case (M3 thread)
New in R2: Exponential brightness control with much lower minimum brightness output
New in R2: 950m depth rating
Using a high-efficiency Cree XLamp MK-R LED, the light outputs over 1500 lumens at 15 Watts – brighter than most car headlights! It has a 135 degree beam angle for wide illumination in front of an ROV. The color temperature is 6200K, similar to most dive lights and ROV lights.
In addition to really high brightness, the Lumen R2 is designed for very low brightness output, which is important to be able to illuminate the scene without washing out the colors or brightness. An exponential brightness curve makes it intuitive to use effectively.
