    I always change mine out every 6 months. I think most of them say they are good for up to a year, but I don't take the chance.

    ok, I heard every 3 months, I'll check the package again, maybe it's the brand that gives different life

    My t5 tube from Arcadia is still putting out the same amount of uvb after a little bit over a year use. I measure the output with a solarmeter.

    I just got a Solarmeter r5 (Don't tell tell Tom I listened to him) and measured my 1 1/2 year old arcadia and it is still putting out the right UVB! Yeah, sorry if you were closer I would loan it out!

    This depends on the type you are using. There are many of them. Some last less than 3 months, and others last for 3 years or more.

    Can you post a pic of yours? Or the package?

    I've never run that bulb, but my similar ones from Arcadia were still making good UV after 3 years.

    @Sterant runs those bulbs and has a UV meter. He can tell us how long his have lasted.

    Yes, but the Arcadia 12% HO tube is a little stronger and must be mounted a little farther away. You've got a good bulb. You just need a meter to set the correct height and tell you when to replace it. The meter will pay for itself, since you aren't buying a new bulb every six months, AND you'll know for sure how much UV your tortoise is getting at all times.

    ok, the way his enclosure is set up I have options to mount it a good distance if needed. what kind of meter, I've never heard of anything like that lol. I'm prepared to invest in a healthy tortoise as long as it's not a ridiculous number... then I can do with less expensive for now How much UVB is he supposed to be getting? just when I think ive learned all the major points, here comes another lol

    This is the meter:
    https://www.solarmeter.com/model65.html

    Opinion vary on how much UV. There are two ways to look at it:

    1. Higher amounts of UV for shorter periods each day, to simulate what happens outside. UVI readings of 5-7 for 3-4 hours a day here.
    2. Lower amounts of UV left on all day. UVI reading of 2-4 here.

    I generally have to replace those bulbs after 2.5 to 3 years. As they slowly weaken over time, I lower the fixture until I can;t safely lower it anymore - then I replace them.

    Do you guys find that your bulb starts to run hot when it’s dying out?

    How are you measuring that? I don't really touch my bulbs all too often ;-)
