It's getting difficult to find good quality bulbs any more. Most of what's available is sloppy, thrown-together junk coming out of China. If you can find bulbs made in USA (good luck), Korea, or Taiwan, those are preferable to Chinese ones. Skip Wagner; their stuff is junk. Philips, Sylvania, or GE are the brands to stick to, and whoever is charging $16/bulb for one of these is a thief.
