The heat generated when the light bulbs are actually dimmed is not from the LED itself, but the electronics that control the dimming. The heat generated is probably at a minimum when the bulbs are actually 100% on.


Any dimmable LEDS I've run run cooler at lower intensities. The
dimming mechanism is in the wall mounted dimmer switch (a phase
triggered triac) - and the ones that change the cut-off point instead
of the turnon work better for LEDs and produce less heat because they
turn on at zero crossing (lower inrush) and vary the turn-off (no
inrush)
