Replacing the AG bulbs

I always hem and haw about replacing the AG bulbs, don't want to spend money on it, etc. But! I just replaced my Pro100 bulbs for the first time since July. Big difference! Very visible change in light. And my bio PAR detectors (Korean red curl lettuce) agree - the lights are brighter. (The lettuce got redder overnight.)
