Actually I asked Ike this yesterday and he said no, PAR reading he took was terrible.
He said some guys are saying they think it has helped coral growth, but he says he can't imagine it does much for growth, and probably coincidence.
They do look nice for color supplement.
I have the 36" toward the front of tank to eliminate shadows in caves.
The main purpose the lights were designed for originally was to add MH like shimmer to T5 only units, and as my T5's came on today I have to admit, these light are excellent for adding shimmer.
I could easily see running just T5's and 2-3 rows of the 36" LED's for same look as halides and having no heat issues.
I'll play w/ the 460 tonight to see moonlight enhancement.
There's a fine line between owning your tank, and having your tank own you!_________________________________________
