Yup, for actinic supplementation LEDs are second to none. The royal blue ones really make the corals pop.
As for running these at 3W I would suggest not to. As you mentioned heat is the killer of LEDs. These are enclosed and passively cooled and that is why they are underdriven. They would probably burn out quickly if run at 3W. So unless he can open upo the housings somehow and add a bunch of fans to cool them I would leave them running as is. If somebody something that runs at higher power but is still budget oriented the Maxspect units may fit the bill or build a DIY array which will be the cheapest option but the most work. The commercial fixtures that are properly cooled and run the LEDs at full power are very pricey right now.

I use Reef Brites to supplement my Radium 20k's(yes I love blue) and they supply just the right POP!

I just picked up a couple more Reef Brites for my frag tank to replace my 250W MH over it (It was a little over kill over a 15x18x12 tank)
I also picked up the mounting bracket for them    Here is the tank with the 250W 14K MH over it  And here it is with the 3 x 15" Reef Brites (Total of 36W 2 x blue & 1 x white)  14K MH  Reef Brites  I also added one over my Freshwater tank 130W PC  48" 40W Reef Brite  I just got them so I do not know how well the coral will do under them but for the frag tank I can add another two Reef Brites if I find that it needs it.
