Try Bulb Direct (www.bulbdirect.com). They have several brands that run around $8 or so. Be absolutely certain that ther is no light leaking from the enclosure. The best way to do this is to go in a dark room and turn it on. You might be surprised to see light coming through plastic panels, or from hinges. From what I understand, hard UV will burn your eyes and may cause skin cancer.
