Rated 5 out of 5 by from Cat mischief The cat had managed to knock over the lamp and broke one of the bulbs. Easy to order and it worked fine. Now I have a second spare one in case he does that again.

Rated 1 out of 5 by from Bulb that did not work I put the bulb in, plugged it in, turned it on, and there was a bright flash and the bulb would only light to a very low light. Removed it and started over only to have hardly any light at all. I am very disappointed as this was the bulb that was recommended by you and it does not work.
