i just upgraded my lighting from 10k 150w HQI to a 14k 250 HQI.

now i know there are definately alot of variables here that can effect this comparison but lets say in general terms if you have the saem style reflector, ballast and bulb mfg but one setup was 10 150w and teh other was 14k 250w what would be the differences in the PAR out puts, would the 14k reduce the PAR output to equal level of the 10k 150w?
