The BlueRobotics Lumen Subsea Light v3 for ROV/AUV is a blindingly bright LED light for use on ROVs, AUVs, and other subsea lighting applications. 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.

It’s housed in a rugged hard-anodized aluminum enclosure with two cable penetrators at the rear, allowing it to go to a depth of 500 m. By default, the second cable penetrator is blank, but the light comes with a second penetrator to allow a second light to be connected to the first (daisy-chaining).

The specially designed injection molded acrylic lens ensures a consistent beam angle in both air and water. The case has a built-in mounting bracket with two M3 threaded holes for mounting to your vehicle. The light operates on 10-48 V inputs and can accept PWM signals from 3-48 V.

It is compatible with many common boards like the Arduino, Raspberry Pi, and PixHawk. The case warms up to a comfortable 55 °C (131 °F) when operated in air and stays much cooler in water.
