I like the single LED flashlights from Coast, but the Rupes pen light really is special. Itwthe perfect color - unlike anything I've ever seen - and it never loses its beam focus. The light just goes from big circle to little circle instead of the circle in circle you see from other focusing flashlights. The only downside is the Rupes is expensive, but if you have the money or are a professional then it's worth it.
Other than that I'd look into making your own stand with different types of light sources.
