I bought a BlueMax 42w Dimmable floor lamp for $200 a few years ago (it is on sale now for $100), before the Compact Fluorescent Light bulbs (CFL's) appeared on the market. The BlueMax bulb did provide great light (similar to sunlight), but I didn't know at the time that it is a proprietary product and cannot be bought from anyone else. I only used the lamp occasionally to do some hemming or altering clothes, so I thought the bulb was the problem when the lamp quit working one day. I searched for another bulb everywhere and ended up ordering it from Full Spectrum Solutions for about $50 including shipping. It turned out that the bulb was not the problem, but the ballast itself, which is also available only at Full Spectrum Solutions (for about another $100), making the lamp not work repairing. Though I got a partial refund on the bulb, I have learned a very expensive lesson: never buy proprietary products that have no reasonably-priced replacement parts anywhere else.
