Description

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

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.

It’s housed in a rugged hard-anodized aluminum enclosure with an acrylic end-cap and two cable penetrators at the rear, allowing it to go to depths of 300m. 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). That means you only need one cable coming from the main watertight enclosure to control multiple lights!

The specially designed injection molded acrylic lens ensures a consistent beam angle in both air and water. Here’s a good explanation of why the dome lens shape is important underwater! An extruded aluminum mounting bracket allows the light to be mounted anywhere. It holds the light with an O-ring (like many bike lights) and has both threaded and through-hole mounting holes.

For those who want to use the light in other applications, like scuba diving, the light can be operated without a PWM signal. Just connect the yellow signal wire to the power wire and it will turn on! A switch can be used here to make this even more convenient.

The light operates on 10-48V inputs and can accept PWM signals from 3-48V! 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.

The electrical schematic, board layout, and Arduino-based firmware are open-source and the design files are available below. Feel free to adapt for your own needs.

Note: We recommend that you don’t look directly into this light to avoid any damage to your eyes!
