This is a curious topic..
I have been using the same hortilux 1000W bulb now for the past 2 years and haven't noticed much (if any) difference.. And there seems to be no exact science to it (as far as i can tell), but many claim that changes every 6 months or annually is ideal..
I'd like to hear/read more opinions on this topic.
And what kind of HPS bulbs have you been using? My bulbs run about $75.00 EA...
