After reading about cree is it needed as its very hard to find here in the UK which is anooying Can anyone help please Link to comment
jestep Posted March 30, 2012 Share Posted March 30, 2012 There's several manufacturers that produce suitable LED's, Cree, Luxeon, GE, Edison. The primary concern is they have enough intensity (100 - 200lm @ 350mA) and they are the correct wavelength. Look for cool white LED's which is generally in the 5000K to 6500K color temperature range. You will probably need to supplement with some blue or purple'ish to get a more pleasing color in the tank.

jestep Posted March 30, 2012 Share Posted March 30, 2012 What size tank are you planning on using this for? The color temperature is good. It's a little low on the output, but if you have enough of these it should work. Not sure about the fixture though. States they are made for a 12V spotlight fixture. Link to comment

I have a 23l fluval edge and it has two mr16 sockets Its the most powerfull mr16 i have seen in the uk so far, do i need to buy cree, i dont really understand what cree is for Link to comment
jestep Posted March 30, 2012 Share Posted March 30, 2012 Cree is just a brand, one of the better ones, but it doesn't have to be cree. You're probably going to want to figure out how to add some blue, but if you have the sockets these should be a good start. They're cheap as well, so if it doesn't work as well as you were looking it's not a terrible loss. Link to comment
C.I._Reefer Posted March 30, 2012 Share Posted March 30, 2012 go to ebay, you could get 2 3x3w cree bulbs for like $20. I would just take the optics off. It should work great, and you will have 18w of cree led power Link to comment
