Mike, I like you.. love radiums and wattage is wattage, but I can attest to the fact that your tank will stay much cooler resulting in lower electric bills... The temp in your room will not elevate nearly as much with T5s and the fact that you can get a dimmible setup..... Well that's simply awesome... I'm assuming that you're referring to the sfigoli attached to your Profilux? If you're running an ULNS, which I'm sure you are, then you won't have to worry about too much of a color shift in your corals. In some instances they may get more vibrant.. The best part about T5s to me , is that you can mix and match bulbs until you have the exact look you want. But, as you know, the shimmer will be gone.. Unless you retro some LEDs to give you that effect. For me, I won't be going back.
How did the CR issue work out?
