Lumen Subsea Lights

The Lumen Subsea Light is an underwater, pressure-rated LED light capable of outputting over 1500 lumens.

The schematic and board layout are designed in EagleCAD.

Lumen Subsea Light Hardware

Features

  • 1500+ lm output
  • Onboard microcontroller (ATTiny45) for programmable behavior
  • Multiple signal input types:
    • Standard servo PWM input signal (1100-1900 microseconds)
    • Direct duty cycle control (with solder jumper)
    • On/off control with no signal needed by connecting signal wire to power
  • Daisy-chainable to allow multiple lights from a single cable
  • Thermistor temperature feedback and overheating protection
  • 6-48V input range
  • 0-2.5A LED output

Software

The software running on the onboard microcontroller is available in the Lumen-Arduino directory and can be installed with the Arduino IDE and an AVR-ISP programmer.
