^^t5s are only good when you can get the 4 ft versions, they are not so great in 2 ft. That is why I asked about space requirements. For instance, I use 2x2 spaces for veg and flower, t5s would be impractical for that. Let's say I used 8 F24T5 bulbs, that's just 16000 lumens. In that same space I could use 4 55w PLL tubes for 19200 lumens. More wattage overall, but I have room to add more.
You could also work with CFLs better in that space as well.
