I still think T5 gives the best color, but I'm not rich and can't afford to replace 16 bulbs a year to light my 215-gallon.Can I say that LEDs have advanced a bit from the simple blue and white LED setups? I'm an early adoptor in a lot of things, but when the technology is still in flux, I'd rather let someone else pay for the early trial years and I'll jump in when it has been more figured out. I've always been value-minded.
