I got this from Amazon for $29.99 It's an LED ring light that can work on 2 AA batteries, or with the DC adaptor. Comes with several adaptor rings to fit microscopes or cameras. I got it for a mobile engraving bench I'm putting together, but I may replace my florescent lamp with this. It may be a bit brighter, but one nice feature is that you can use left side or right side lighting. It also works pretty well for coin photos.
