I plugged this bulb into my Lights of America sun light lamp the moment I got it and was disappointed to find it not working. I wasn't especially surprised--I could hear the coil rattling around inside. The frustrating thing is it wasn't even worth the trouble of returning, just a waste of $10. I like to give sellers the benefit of the doubt as far as the packaging process goes but ought to have have heeded the other reviews on this one. I would have to recommend going with another seller.
