Led debate for rsm 250

[Cankers]

Hi everyone! Long time lurker finally got an account fully setup and wanted to start contributing to the site . I'm currently debating a DIY led upgrade for my rsm250 to help control the temps in my tank. I like the fact of the lights to be dimmable and have more control. I was looking at the kits provided by reefledlights.com It will use the storm controller with cree xt-e leds. Any opinions? Yay or nay? Lol
