    yea I guess .07 (christmas lights)watts per led just doesn't have the depth no matter how many there are. probably would need to be an inch or 2 away for growth but then there would be no spread.

    I bought the PAR 46 bulb Nick28 mentioned on reply #9. I removed the lenses from blue led and know the bulb doesn't go on. Why?

    Did it come off easily, or did you have to wiggle it quite a bit? If the latter, you might have busted it. The whole array or just one one LED?

    When I remove screws from cover plate all optics just splatter all over the table.

    The optics actually fit into slight depressions in the cover plate on these types of lamps. You put the cover plate face down on a flat surface and place the optics in them, then to put the plate back on you have to very carefully put the base over it so that everything lines up.

    I changed the optics in a PAR 38 recently from 90degrees to 120 degrees doing this.

    Note: the optics also act as a spray and water barrier as well. if you don't have them there, you will eventually short out the LEDs.

    If you wiggled the LED's at all you could have broken a wire somewhere. This would cause it to not work.

    Thank you rleahaines, I follow your instructions, it took me like 1 hour but I reline the optics and now it's working again. I was trying to remove optics because I'm only having algae grow at the center of screen, but bulb doesn't work without optics unless any other way of doing this.
