depends on how many really. i have a 36" actinic reef brite and its not going to really increase growth that much, but more of add the led shimmer look and 1 strip can pierce through 6-t5 bulbs. i had it on a tek elite 6 bulb, and the reef brite is so bright you can easily see a difference when i turned it off and on. i mean, if you get several reef brites like ocean gallery II has over there big new shallow reef set up, its the reef brite fixture which consists of 5 reef brites together, then yes, it can grow and have coral thrive. but 1 strip...more for visual effects.
