UVB in a mvb

[tyguy35]

Does anyone know how long the UVB lasts in a mvb bulb?

Some member was working on that. Not sure who. It is suppose to last close to a year, 9 to 12 months. I was told, when I bought my tort. last year that they lasted three years. However, I am learning that is wrong info. So, I am switching mine out at a year. Still can be used though for heat until it blows.

Any way to Tell when the UVB have all gone

Unfortunately, you have to be proportionate in costs.

Assume an MVB is out of UVB after 9-12 months and a tube UVB light after 6 months.

Any money spent on a UV detector would take some time to recover.

I would factor in exposure to sunlight as well. If your tortoises get outside more often then not, I wouldn't worry about the diminishing UVB from the MVB and would replace it annually. Probably right at the start of fall/winter so the MVB is most effective while they get outside the least.

That said, personally, I wouldn't rely on a bulb as my main source of UVB without having a meter to test the output.
