LED Height

JTL · 01/13/2012, 12:50 PM

How high from the bottom of the light to the top of the sand are people placing LED lights. I have 8 Par38 lamps at 33" now but recently had them at 30". I like the look better when they are higher up and time will tell if my corals like it. On that note some of them appeared to be bleaching out at the lower level. I am going to build a strip of all royal blues and place it between the two rows of par38 and see how that looks.

Hi JTL, what's the beam angle?. That's really important cause you can find from 10 even less degrees to 120.

40 degree optics

We use to put 90 and 120 degrees with really nice visual aspect and perfect results with soft corals or animals that usually needs less lighting levels.
