Product review (5 stars): Cool, Clear, Bright Bulbs
My last bulbs stayed on when the door shut and melted the plastic housing.  I had the unit replaced and supposedly fixed but replaced the bulbs with these led units just to be safe.  I can leave the door open for a minute and feel the incandescent bulb heating up but this led one stays cool.

I attached a photo that somewhat shows how much brighter and bluer the led bulb is.  It's clearer when you see the bulb in use.  The electrician who fixed the unit said they are replacing most bulbs with leds to save money.
