Here's another comparison image I found interesting last year. I think for one 1000W bulb I'd need 25 of the T5HO; or in my case 50 since I run two 1000W systems.

I get about 8x8 grow area per light, with 10x10 supplemental - give or take with overlap. So I have about a 16x8 solid grow area.

And if the below chart is correct, I could probably just purchase 5000-6000 bulbs in the future.

I'll admit some of the K value stuff, etc is over my head at this point still.
