Whilst constructing the latest Dual Head video Lights - http://subsurfacetech.synergize.co/LEDDualHeadProject.php
It occurred to me that the same technology could be employed in my primary dive light which is a 35watt HID.
As a primary light it is perfect, but for Video it leaves a lot to be desired - you can follow the integration here

The light can be run in Automatic mode - meaning the controlling MCU changes the power setting to the LED's based on the Heat Sink temperature or in manual mode where the power setting can be changed by swiping a hand across the face of the lens.
A more detailed description of the control logic and how it is implemented is currently under construction and will be posted when completed.
