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

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?

There are many LED manufacturers to chose from so likely the answer is no. Specially for white LEDs can be quite a difference among the various types and brands on how natural the light looks. CRI (color rendering index) is a measure of how accurately a light source illuminates objects' true colors. The larger CRI the better.

If you're thinking of doing a DIY panel, you're not alone and there's likely a lot of stuff on the web discussing what works and what doesn't.

I think LED fixtures are finally getting to a point where bang-for-the-buck is getting more realistic, though I'm only a fan of them in situations where batteries are a must. This year saw some very good products hit the market though, I'll likely get a couple units for video work eventually.

I see, Thanks!
