You can use various numbers of LEDs, depending on their power, on the configuration you use, the optics you use, how far they are from the top of the tank, etc. Here is one empirical way to determine the number: http://www.plantedtank.net/forums/sh...d.php?t=168999 __________________ Hoppy

Thanks for pointing out the mistake hoppy.
I have your excel calculator but could make it work
Maybe you can answer it then- If kept 5" above the water level, with 60 degree optics, how many LEDs to be used for a 60-P. [24"x12"x14"]

Just an introduction for the beginners who wants to understand what LEDs are all about. Pardon me for not listing all the colors. I'll look into it and will add the info. I'm also still learning.
