Simple question....
How do you know it's time to change your T5 bulbs?
I'm running ATI dimmable units and was trying to figure out how I should know that the bulbs need changed. PAR is still good but I can't measure the spectrum, which is what I'm thinking goes first. Is there a scientific/engineering method that works? (Not really looking for an answer like "I change every 6 months")
