I have an ATI 4x54w dimmable sunpower light that came with the tank I bought from local reefer. He said the lights were only few months old but I just got 4 new ones from brs , black Friday deals. The tank is still cycling but was thinking of taking current bulbs out and burn these for 100hrs at 100% to burn them in while the tank is empty of life. Then take them out and store them for later use. Will these then be able to be dimmed at that point since the burn in period was already done? Do ATI bulbs need to be burned in before dimming anymore? Thanks for any advice as I'm new to T5
