I "think" I have decided to use 8 foot fluorescent T8 strip lights with 4-4 foot lamps in my new shop. I can get these in either a high output or a normal output fixture. I haven't had much success in determining which might be the best way to go. The high-output fixtures are more expensive, but I don't mind spending the extra money if they would be the better choice.

1. Do both use the same T8 bulbs or does the high-output fixture require a high-output lamp?

2. Are there advantages/disadvantages that I should consider in making the decision?

I have considered using T5 fixtures, but I have pretty much eliminated them from consideration based on cost plus I'm not sure I would like the brightness at the 10' height of my ceiling.
