how often to replace T5s

Thanks Ross, I checked it out and will look for one with similar features from a Can source.

Hey Oscarman
I cannot recall the brand right now (will go home and check tonight though) but I picked up my light meter from a store called HD Supply in the west end (184st I think). About $90, but easily the best thing that I have purchased for the hobby! HD Supply also happens to be where I purchase all my T5 bulbs from as well.
