Will a repti glo 10.0 UVB T8 bulb work in a 40 W T12 fluorescent light bar?
Nobody has any input?
I honestly don't know the answer to this. If they are the same size I would assume yes, but I am speculating.
Yea this comes up because I'm getting ready to build some hatchling racks and I have 4 48" T12 fluorescent light bars already... The UVB lights are T8 though... And if I could just use those instead of having to but new ones... That would save like $80
They are the same length, 4 foot.
However they are different wattage, with a newer "digital" (solid state AKA electronic) ballast, it would be OK, but an older rig with a starter and coil ballast it would shorten the life of the bulbs.
Does your fixture have one of these??
I don't recommend this, they will fit (the pins are the same size) but you won't get as much output and you will end up buying new bulbs in a couple of months, if not sooner.
I agree, the ballasts are designed for a certain level of output. As well T8's have an electronic ballast.
I wouldn't doubt if the bulbs flicker a lot.
You could always change out the ballast.
A new ballast is more then a new fixture
You should get a T8 fixture
You should do yourself one better and get a t5 fixture...preferably HO
vers makes a good point
So a T5 will work with a T8 bulb??
They are nice, but pretty pricey from what I've seen. Are they not?
No, the T8 bulb pins will not fit into the T5 fixture.
So then that's not a valid solution to this problem... Do they make T12 or T5 UVB bulbs?
Yes, actually Arcadia makes some really great 12% T5s, which you can find at lightyourreptiles.com. A lot of fixtures are pricey, but those listed on the linked site are not bad at all.
Yes those are quite cheap compared to anything I've seen.
Just an update.
We had to replace some T12 fixtures in our shop. Talking with the electrician. To change a T12 to a T8, you have to change the ballast and the ends as well as they are different pin configurations.
This is the light unit I use for mine, it's good for T-8 and T-10 bulbs!
The Exo Terra 10.0 UVB 36" and 48" are T-10, and shorter bulbs are T-8

Interesting. Now would those have to be their own specific bulbs?
Likely have unique ends on them?
