Product review (5 stars): Ignore the bad reviews that say these bulbs don't work.
I bought 2 packs of the GE Lighting LED 83645 4.5-watt 350-Lumen A15 Refrigerator Freezer Bulb with Medium Base, 1-Pack. One worked fine the other one seemed to not work. I removed the bulb that worked and screwed it into the other socket and it didn't work then either. I unplugged the refrigerator and used a small screwdriver to bend up the metal tab in the center of the socket a little bit. Now both bulbs work perfectly. They made my 22 year old refrigerator look brand new. Very bright. Ignore the bad reviews that say these bulbs don't work. They have problems because the last bulbs they had installed were screwed in to far and bent the contact tabs in like one of mine was.
