What I’m saying is if the heatsink on the back of the lamp is tiny or non-existent there will not be much power/light.
It’s any easy way to weed out the posers when shopping around.
If you look at cars with LEDs, they have a string of bulbs, not just one. One bulb is not going to do it in a housing built for standard bulbs. I think I’m repeating myself.

@bing. There is more than one Diode on these lamps. Most have between 4 and 12.
