I too own the Lampcraft 'Concert II' lamp, http://www.lampcraft.com/product.htm

I have to admit that I have mixed feelings about this lamp. I really appreciate it for its very lightweight sleek design, and that it also includes a built in battery pack, as well as can easily clamp securely to almost any portable music rack. My issue is with its flourescent tube. Even though the tube is color balanced (daylight color temparature with a bluish hue) and provides non glare even illumination, I can't get over the annoying sensation that the light is continously flickering (universally inherent design of florescent lights).

I remember quite a few years ago that many school districts across the Country (US) replaced all florescent lights with incasdecent lighting fixtures in their classrooms because they discovered students working under flouresent lights were less able to concentrate.
