Steve,

Can you please explain how actinics produce "false high" PAR readings despite the fact that measured PAR values for actinic T5HO lamps are considerably lower than whiter lights?

For example:

ATI
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?
