bulbs and batteries confuse me, quality wise. i saw one of those expose shows talking about batteries, and they tested them and found very little difference in battery life/quality. there was a huge difference in prices though, of course. i figure there is a lot of mark-up with bulbs also, and quality is prob. equal to or better than the, "big name," bulbs. hell, aren't almost all of them made in china anyways??? prob. just a matter of the name they stamp on the bulb/packaging, lol...
