I bought this lamp in December and by March it stopped working. I thought it was the light bulb, so I sent for a new one to Grandrich. The bulb, incidentally, cannot be found anywhere else, except at Grandrich, and it took about 3-4 weeks to get. Even after installing the new light bulb, the lamp did not work. Next, Grandrich sent me a new ballast. This is a part you need to install at the bottom of the lamp by reconnecting 7 pairs of wires after you remove the old ballast. The lamp worked - for two hours. Again I contacted Grandrich, located in Cerritos California about an hour's drive from my home. They suggested I take it in to get it fixed. I was not inclined to spend at least two hours in LA traffic and wait for the fix. What if the fix does not work? I requested a replacement lamp, well aware the new lamp may be just as bad as the "old" one. This they refused. I don't believe it's worth pursuing the matter any longer, so I am dumping the lamp. Any potential customers beware: the lamp and the bulb are made in China and you wont be able to get the bulb even in your better local lamp store. Grandrich appears to deal exclusively with Chinese products.
