This set of 2 GE Appliance (21188) 40-Watt was only 50% what I expected. I figured I could replace a blown stove light bulb and have a spare bulb a few years later. He defecated in 3 seconds. Is there something wrong with the electrical system of my cooker? nope Then I screwed in the second bulb from the kit and it worked fine. 2 stars for durability as I've already spent 50% of my purchase. I will not be returning the kit although I would prefer to keep the bulb that works.
