Some of you know already but most don't. I have ran a very successful tank with 3 250w Mh's since 2008. I rarely had any problems with growing corals or getting them to color up nicely. It was time to replace the bulbs, so instead of spending 300 bucks on new blubs i made the decision to make the switch. I have been watching, reading and forming my own opinion. I am a fan of those big companys that spend a lot of time and money into research and development. So I decided to go with 3 Ecotech Radions. I got a great deal on Gen1 with the TIR lens. Brand new, never used.
So i started with replacing the middle HM with one of the radions. After a month of use, tweaking the graph, getting used to the light i added the other 2.
So far i have had to move my superman monti out of the main tank, the rainbow monti keeps receeding and my tyree undata has lost color. Other than that everything has stayed the same. I have noticed my palys seem to be streching for more light on the bottom of the tank. I am still tweeking and increased the intensity a bit. Still looking for that sweet spot.
For me its hard to tell if I have enough light or too much. Based on the palys streching for light i don't think i have enough. At peak the intensity only gets up to 70% and i think its only at that for an hour.
Welcome your comments. Also now need to relearn how to shoot pictures under LED's.
Here is a quick video of the setup shot almost a month ago.
