Cree Reef-White 27W LED-Aquarium-Bulb? Good?

[MoreDakka]

Hey,
So as like most people, trying to save a buck but also trying to make sure it works properly for a reef tank. I ran across this:

Which prompted me to search more:

Are these good or no? Will these support a reef tank? It seems that if I can run these in a regular bulb socket I can save a bunch of money that way. Any opinions on these?

Both links already dead?

Well lets try again:

Tested and working links this time.

Par38 bulbs like this have been around for a while.
I run my 12 gallon off of one of these bulbs.

There is a ton of info out there as to their effectiveness at different depths.

If your tank is 18" or shallower, these bulbs should do the trick.

My tank is a 45g, 36Lx 16Dx24H. Could I do 2 or 3 of those to save some money on a decent LED system?

Thanks.

In short, yes.
Just don't plan on keeping sps or clams without doing some more research.
LPS and Softies, palys/zoas should be fine.
