Can I ask Omni what distance you have your young plants from your leds? I have a low height vege area and occassionally the taller ones get a touch of light bleaching, and I don't think its the PL-L thats in there with them. Just curious.

In general I keep them about a foot away, but I have kept them as close as three inches. I don't seem to get any bleaching issues except when I put my UVB bulbs too close.

On a side note, my friend does get burning with high higher watt LEDs. I think these 120 watt (80 actual...) are low enough wattage to avoid burning.

Personally I would prefer several low wattage lights compared to fewer high wattage lights. This allows a better spread of the light over the canopy area, helps avoid burning, and such... Of course it also means more power bars, timers, extension cords, etc... so it costs a bit more.
