For the curiosity in us (me) I decided to disassemble a half dim H11 LED bulb to see what makes it... Light!. There is not too much going on inside of these LED bulbs. looks like a couple controllers, and 3 micro LEDs per side of the bulb for 6 micro LEDS total per bulb. The aluminum casing has a couple "heat sinks" attached for cooling of the motherboard... 3 "special" triangle shaped screws hold the case together.
