Well I went to Adams today and did some measurments on his lights today.
His set up is the 400 watt Radium 20K and three 30 watt NO actinic bulbs 12" distance = 343.09 PAR 18.5" (bottom of tank) = 269.9 PAR I think it was 4" of air and 8" of water (Adam can you conferm this? I need to know how far it was from the bottom of your bulb to the water) Steve
