Sun Pro 357
Aquablue 336
Blue Plus 311
Actinic 137

How does that actinic lamp running at 137 PAR some how artificially create "false high" PAR readings when the measured PAR is less than other lamps surrounding it?

dimmer bulb, who knows how they are made. anyways I am trying to get my house painted so I can sell it so I don't have time to explain it again.. Go to APogee's site they tell you what there corection factors are and such. wanna buy a house?
