A custom LED array made with RadidLED parts and an collection of CREE LEDs for a good color range. I don't remember the specifics. It is connected to a Storm controller from RapidLED and has a while channel and a blue channel. Also its wired with an ethernet cable for single one cable connection.
Here is an album of the array and some simple phone shots for color. Intensity is controllable with the controller. This light grew Montis, RBTA, and a nice Crocea clam.
