When I started replacing lamps here, I picked up a simple spectroscope, sold as an aid for jewelers, but more of a toy really. It's more than sufficient to show that CFLs have a terrible spectrum, a lot of lines with stark gaps inbetween. All LED lamps I have checked display a continuous spectrum, even if there is some banding visible, in particular at the blue end. -- Christian "naddy" Weisgerber naddy@mips.inka.de
