|   Ok I borrowed a par reader from a friend.  Comparing between T5 and LED.  At full blast on both channels, 24" tall tank straight down, 1/4 down from surface where the first coral - 305, on sand 105.  My 16" tall breeder with 4 x 39 watt T5 - first coral on top - 176, sand 98.  And to my astonishment, my 40 gal breeder tank looks much brighter than my 3 ft x 2ft x 2ft tall tank under this LED.  Looks like through naked eye this LED put out more intensity than i can see. |

|   I have 3 units over my tank, all running at about 50% and I have to watch where corals goes because I can bleach them way to easily. I lost a few frags when I first started with these lights because of that.
