Sorry if this is here already, didn't find it.
What makes a GU10 or similar LED lamp "Dimmable"? Given that a simple LED works on 3volts or so there must be something in the enclosure to allow 12V working. What do they use?
Switching regulator?
Resistor?
Cut one open?
I need a bright dimmable COB style, preferably about 10W. The type with a lot of separate leds won't suit.
(One with a good CRI would be best)
