It’s time to change my bulbs. My specific scenario is that I don’t run my lights @100%. I’ve seen people state that if you don’t dim it doesn’t matter and they change a bulb or two at a time over a few weeks.. Do they not need 50-100 hours straight? My scenario is that I don’t ramp up and down but I run them less than 100%. Running at 100% would be to much light for the tank. Anyone else ever in this same situation? If so what did you do?
