Thanks for the info Fletcher.

Below are additional photos. The first photo shows the LED 500 illuminating a color chart underwater to show color rendition.



Next to compare illumination intensity expressed as Lumens, a 35 watt halogen reference light was aimed at the meter with a Lumens readout of 6680. Below that is a Greenforce HID 10 system with a Lumens readout of 3271. Next below is the TillyTec W30 backup light with a Lumens reading of 7810. Last of the light photos is the LED 500 with a Lumens readout of 10280.

The last two photos are the mounting system to hold the battery pack.
