Alright, I've decided to go with T5 lighting with LED moon's on my 20L nano project. My questions are:

How many bulbs do i need? 2,3, or 4?

What brands are known to be good? Also, those that are known to be bad?

How hard are retro'-kits to put together?

How well do retro's preform compared to manufactured fixtures?

Thanks again!
