Is this a T5 bulb? / Is this ok for baby paphs?

[DeanneD]

I have an old 10-gallon aquarium that I want to use for deflasking some paphs. The description of the aquarium light sounds like it could be a T5, but I don't see that it says T5 on the bulb itself. I remember when I bought the aquarium, I bought the bulb separately and bought a more expensive bulb. Is there a way to tell for sure it's a T5?

Assuming it is a T5 bulb, will this work to start my baby paphs? It's only a single bulb, but I also read that baby paphs don't want a lot of light. I want to put them in the aquarium in S/H. They'll be in a north-facing room in front of windows and under skylights, but from what I read, that's just about as good as being in a closet as far as lighting goes.
