Lumen Light R2
Introduction
This page is the most recent Lumen documentation page. If you have an older Lumen Light, you may wish to refer to the
archived documentation page: Lumen Light R1 (Retired July 2018) (http://docs.bluerobotics.com/lumen/).
The Lumen Light is a sealed LED light which can supply up to 1500 lumens at depths of up to 950 meters. The Lumen Light can be
smoothly dimmed with a servo PWM signal or simply turned on/o with a switch. Up to six lights can be daisy-chained together
and controlled with a single signal, requiring only one penetration into a watertight enclosure.
Quick Start (on/o with no PWM signal source)
1. Connect the power wires to a power source
Red: +10-48 volts
Black: Ground
2. Connect the yellow signal wire to the the power wire directly or through a switch to turn on to full brightness
Quick Start (dimming with PWM signal)
1. Connect the signal wire to the appropriate microcontroller pin
Yellow: PWM (3-48 volts)
2. Connect the power wires to a power source
Red: +10-48 volts
Black: Ground
3. Provide a servo PWM pulse from 1100 μs (o ) to 1900 μs (brightest)

Using the Threaded Holes The two threaded holes are best used when you have access to install a screw that tightens into the holes. This applies to most ROVs. -
