The aquaticlife 'actinic' bulbs actually have a peak at 420nm and 460 nm. The 420 allows for better fish coloration and fluoresence in your corals, while the 460 peak simulates spectrum at depth. At the end of the day, all that really matters is that your corals grow, have great coloration and you get lots of coralline algae growth. Maybe i am over simplifying here, but that is the overall goal. If you check out the RC site, you will see some extensive reviews on T5 stuff there. If you go to the aquaticlife, they have full test results from an independent lab that actually measures the par and spectrum of all their bulbs.
