IMHO the bulbs are defective. in a table lamp. I think the problem is that the solder on the bottom of the lamp is not thick enough to make a good contact in the mounting block.I hope someone from Sylvania can get in touch with me to solve the problem.If you check my purchases I have done a lot for these and larger bulbs i like the 30 degree beam angle and i use the same bulbs so all downlights look the same the price has gone up dramatically since i ordered them on may 15th 2016. from $31 to $61!
