Light type for seedlings?

I noticed that some folks having LED light strips around their plans, or even led tubes in the corner of their grow tents/enclosures.

Is this a necessary approach to prevent light burn, or, can I start the grow with a regular LED light position high?

Thank you!

they'll be fine. i run a 580w led 24" above my seedlings with no problems. have done ever since i switched to led.
