Hello, I have a basking light already so what should I use for the UVB light?
Okay thank you. If I go with the MVB do I need a ceramic heat bulb for the nights?I live in south texas and our house is set at 70 degrees at night.
I have a 6 in russian tortoise. I teach and coach so I can't get him outside every day.
I have dogs so I won't be able to put him out as often. Where would be the best place to buy the mercury bulb?
Not necessarily. The life of the UVB bulb is more dependent on how many hours it is on. If I look at indoor winter use with no outside time - A MVB used as basking heat as well as UVB needs to be on about 12 hours per day. I use a 12.0 HO UVB tube and only have it on 4 hours per day. So only 1/3 the hours burned per day. The basking heat provided by a very inexpensive standard flood. A lot of the year the UVB bulb doesn't need to be on at all this way when they get outdoor time midday yet need to come in and still have light early morning and later afternoon. With a MVB I would have to have it on then, while the tube type can be left totally offThe MVB needs replacing every 12 months and probably works out cheaper than option 1
You have a choice.
1. Get a UVB tube light and run that with your basking bulb. The tube will need replacing every 6 months as it loses effectiveness
2. Get a Mercury Vapor Bulb and use that on its own instead of your basking bulb as it does both jobs. The MVB needs replacing every 12 months and probably works out cheaper than option 1
