A 24 cree LED on a 6x9 heat sink will put out a few hundred PAR at 24 inchrs. The cree xp-g are **** powerful. Look up the radion fixture. It uses 32 or 34 cree LEDs like the ones rapid LED sells. The radeons are designed to light up a 2 foot section of tank.

There is also a video on youtube, rickets reef diy LEDs he has a 48 LED kit from rapid LED over his 90 gallon and can grow SPS with ease. There is also another video on youtube that has a 120 48" tank with 48 cree LEDs that puts out a few hubdres PAR on the sand bed

i do agree that the hydrofarm fixtures are excellent for your application.
I know of one fixture that uses one led, the exotic canon led fixture. Now this is one powerful fixture. It might be able to cover that

You'd have to place a cannon a few feet above a tank to get the spread you want and really at that distance away I wouldn't think much PAR would be availabe

i called them about those canons. they said that you would need 3 or 4 of them over a 4' tank. not as powerful as would be expected, and we're talking about 100 watt LED's, not 3 watters.
so that's 400 watts...i might as well use T5s or halides even.

Wow 3 or 4 over a 4' tank? yeah for that kind of money I would just use a metal halide and a t5 combo or even just a t5 fixture. I thought they were more powerful then that.

Yep. Whatt do you expect from a light that is 3 inches and is a point light. Why do you think LEDs are placed in mass amounts. They are not designed to light up large areas on their own so what would a 100 watt or 250 watt cannon be any different

I would have though with the high power you would have to place them a foot above the tank, giving them a wider "effective range" but in this case I guess not

The spreed on such a small diode could really never spread out that much. And no optic would even give you that option

Agreed. It's only good for really deep and tall tanks such as column or Cylinder tanks.
