Well I got a chance to work on the light over the weekend. I wired it up, and switched it on-"full blast" for the first time. I'm still seeing "little blue spots", all six of them to be exact..... sorta like- when you look at an arc welder in operation. The word "bright" has been replaced by "intense" when it comes to describing the quantity of light emitted by this unholy contraption.
Just for fun- I threw this thing under my tanks hood to see what an extra 300 watts of LED would look like. I already had 270 watts worth of Cree XR-E's and adding this thing would push that number to 570. The result was photosynthesis on a scale I'd never witnessed before. Prior to switching on the additional lighting, the tank water had already exceeded it's maximum oxygen holding capacity. All the plants in the tank were actively pearling.Within 2 minutes of turning the new light on, the tank water went to what looked like- "boiling". I have never seen anything like it. My ph controller went crazy and I had to up the Co2 flow rate just to keep up with the extra demand. I let the new light run for another 3 hours for a nice "burn-in test" and it did well. I plan to run it for at least 8 hours non stop this weekend and take some temperature measurements to make sure they're within spec, before I call it done. Here's a couple of photos of this thing in action. My camera can't do it justice though.
