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
