Are all T5 bulbs the same?

[RFheavy]

Heading down to the hardware store and I'm thinking about messing around with a t5. Is there anything in particular about those bulbs that I should be mindful of?

I will only add a product review to stay away from Electrolux t5's. I might have gotten 2000 hours each, of two. I'm sticking with GE.

just keep an eye for the ones that say HO or high output, theyre a bit more efficient than regular ones

They have vegging tubes and flowering tubes. If you are using them for vegging, you need a blue spectrum. For flowering you will need a red spectrum.
