I have finally been able to fit these bulbs into our fixtures. I decided to test the whole box of 10 at once. Unfortunately 4 didn't work, the case seems too loose compared to the 6 that worked, so the connection is poor on the 4 that failed. I will say that for the price of 6 I can use it's still more affordable than buying it at the big hardware store I bought them from. However, the manufacturer needs to fix the flaws as all 10 should work. I would add that the light is clean and bright white which is what I wanted in our master bathroom.
