@CooperDragonWhich meter is more necessary to have the 6.5 reptile UVI meter or the 6.2 uvb lamp meter.
Also what’s the best UVI reading for a bearded dragon. Iam using T5 12% uvb with reflector
Don’t quote me but I think coopedragon told me once the 6.5 was better comparing uvb output from different bulbs and to check a bulb for output and see how much decay the bulb has had. That way you can keep using the bulb until it’s stops producing useful uvb. A lot of the high quality uvb last much longer than a year.
