Blue Robotics Lumen Subsea Light (Pre-Connected Sets)
These are pre-connected (daisy-chained) sets of Lumen Subsea Lights, making easy to install two or four lights with a single penetrator to the watertight enclosure. All lights will respond to a single signal. The lumen have a depth rating to 500m, better low-light output, and a wider brightness range.
Some of the new features are:
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
Built-in mounting holes on the side of the case (M3 thread)
Exponential brightness control with much lower minimum brightness output
500m depth rating
In addition to really high brightness, theLumen 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.
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.
