LEDs treated me well for a good number of years... using the cheap Ocean Revive LEDs no less. I ran them with T5s on the side as well. Currently running Radions with T5s on the two frag tanks and they look great as well. I just prefer T5 on my display... better coverage and I like how the SPS respond to the T5 lighting. Adding the SBREEF actinic bars have me the pop I love from LEDs as well.
