I like LEDs but I make my own,don't like the cheep ones on the net.
I like t12 Fluorescent lights in 5000-6500k.
T 8 are too hot for my shelves and don't or didn't come in the 5000-6500k I liked in the lumens that the t12 come in.
My grow room has no windows,it stays 80 degrees+ even in the winter.
Gets too hot with only 2 shelves of 8 t8 fluoros on them.
t12's were no problem.
I think the t8 ballasts get a lot hotter.
Never tried halides or cfl's due to heat...
LEDs are best if you get the right ones.
The cheap ones are crap for the most part.5mm LEDs with no lumens.
Good for suplimental light for branching but too weak for what the seller claims they will do.
Some will work for sprouts but only that at best.
They aren't any better than fluoros.
I'd build my own LED panel for a few $ more if you want to go with LEDs.
LEDs can be built with the wavelength plants use.
Other light sources aren't,in general as light wavelength specific.
Get shop lights and get bulbs in the highest lumens you can find in 5000-6500 k for your starter plants.
Cheapest way to go I think.
