White LEDs are really interesting!

[@deltakid0]

There are some buzzwords on LED lights which are not clear for me so the question is: what is the difference between COB, CSP and CREE lights? Thank you.

Hi Iván! CREE is a very popular brand of LEDs, kind of like GE or Lumiled are brand names. COB stands for "Chip on Board" which indicates that the LEDs are integrated together more tightly and, as I understand it, earlier in the manufacturing process. Sharing a semiconductor substrate rather than sharing a PCB. CSP stands for "Chip Scale Packages" and is a way of packaging discrete LEDs into something smaller so that you can fit more of them onto a PCB. It basically is getting rid of all of the "unnecessary" plastic and metal that surrounds the LED itself to make the unit as small as possible. I hope this helps!

Why led bulb-lights size don’t work properly in a set of lights?

[@CircuitBread]

Hey Isaias, I don't actually don't understand the question. What are you referring to?

[@Romiman1]

Many of these "sets" are 12V Halogen-Sets. And their drivers/ballasts need a minimum load. And LED-lamps are way below, so the ballasts don't work properly.
