Photo/Video Led light Panel Leds? Are the leds in the panels the same?

[haring]

Question is simple. Do photography/videography led light panels use the same led light bulbs
Do Aperture, Younguo, 1 x 1, Came TV... use the same light bulbs in their led light panels?
Prices vary between 100-300 and 1000-15000 USD for the same size light panels. I know they are different units, cooling, etc. but I am just wondering whether the BASICS of these units are the same: the individual light bulbs...Are the light bulbs the same?

They don't use the same LED lights. There are different classes of LED lights even from the same manufacturer.
