To really confuse you, may I suggest you get LED lights?
Bright Daylight bulbs cover the same light spectrum as bulbs labeled as grow lights but are cheaper. The important number is the "K" which stands for Kelvin - a measure of color temperature. You don't even want to know what that all means except that you want bulbs, whether T-8 or T-5, that are rated near 6500K.
I use a T5 light over my terrarium full of Masdevallias because T-5's give out more light with less heat (and Masdevallias hate to be too warm). T-8's will be much easier on your pocket book but do give off more heat. Don't buy T-12's - they have not been made since 2014.
