I recently set up a 7ft, 210gal tank. I got 4 black box LEDs with the setup. They are ordinary black box lights (12"x8" I think) I set the lights 6 inches apart and 10 inches off the water. This is a pic of my display with the lights. I am getting very bad spotlighting effect.

I was very unhappy with the coverage of the lights at 6 inches apart. Then a friend of mine @litenyaup noticed that each LED had a lense on it and said we should try removing them. To see if we could get more coverage out of the lights. It's a lot of lenses.
So after we took down my lights and removed all the lenses this is the new coverage my tank is getting.

The spotlight effect is completely gone and the tanks looks much better. I don't know what it did to the par but my corals are all still extremely happy. Just a consideration for anyone running cheap black box lights. My lighting is much better now.
