Just what my mom needs Optical Christmas tree. The first was also from Philips and lasted 8 years until I knocked wood off the table while it was on so it could have lasted longer. Of course, the tree is only used about a month and a half a year. I have a couple of Philips bulbs, a couple of LED and landscape lights, large 13 watt 120v CCFL bulbs and 20 watt black Philips bulbs. They all last a lot longer than the cheap nameless junk brand.
