    Hey all, A local reefer just sold me 2 of these bulbs for $30. He said they were 2 months old. Im new to mh lights so I was just wondering what would be the best way to figure if the bulbs are still good. Thanks

    Not sure there is any way you could tell unless you have a spectrometer. I am not positive but am pretty sure there will be a spectrum drift as MH age. You can try pming one of our lighting sponsors for the answer.
