T8 vs T5 HO vs (maybe) LED?

Some of my tomato seedlings got switched to the LED after potting up.. and some of those are looking very distressed. None of the seedlings under T8 are showing the same stress. So I am having second thoughts about whether a simple LED shoplight is fine for tomatoes. Maybe just the combination of transplant stress + ??? I could say higher lumens but the light is raised higher to compensate for that. Hard to tease the causes apart, they would be colder because less heat from the lights, spectrum at 4000 K is different, add water to that.. etc.

Im just guessing that the wave length is incorrect. Im thinking that to get in LEDs, you have to bite the bullet and spend the moolah to get the real deal.
