I just did a ton of research on lights because I'm going to be setting up shelves and lights for growing tomatoes to sell in the next month or so, and ironically, I'm going to go with my old system of fluorescent tubes (T-8) with GE daylight bulbs. The LED lights just don't have the spectrum I want for my tomato sprouts. This is what I've decided to buy (and what I used before to grow tomatoes indoors with no other natural light, with great success). Total cost including bulbs = $26.00 plus tax. This shop light doesn't have a turn off switch, either, but it's the cheapest option and I can run an extension cord to an outlet that's on a switch.

Home Depot doesn't carry the GE bulbs anymore, but Lowe's does.
It kind of depends on what you want to grow under the lights. The LED lights are the coolest temperature-wise, and use the least electricity, but they don't have the best spectrum/lumens for tomatoes, which is what I want to grow.
This is what I learned, and hopefully I understand it correctly.
Daylight color spectrum is roughly 4000K - 6500K.
The higher the numbers = the bluer/whiter the spectrum = best for fruits/veggies.
The lower the numbers, the warmer the color spectrum = best for flowers.
So, for my tomatoes, the optimum is 6500 K (bluer spectrum), and I wasn't able to find that in an affordable LED bulb.
I never had trouble with the above GE bulbs burning my plants.
The LED bulbs are getting better all the time. When they can give me the spectrum I want at an affordable price, I'll be switching. I love that they don't give off heat and are cheaper to run.
