Amazon is the best place to buy those new. 5 These type of led don’t last long and the spectrum is poor.

what makes a led light have poor spectrum? If a Chinese box light has an assortment of leds ranging from 420nm up to 660nm and is the proper wattage what really distinguishes it from the more expensive lighting. Is it the layout of the leds or the brand of led bulb or both?

Both the chips quality and the number of bands that covers the entire spectrum.
Especially the spectrum quality of the white led and the violet/near UV led at 400 to 420 nm range.

I have been debating on changing to mh t5h
If you want to go this route, used MH/t5 combo is still a good choice if high quality bulbs are used. A used MH/t5 fixture is cheap, but the new bulbs can become expensive quickly.
