Magnification is 2.75X.  I used 2.0X for most of my dentistry, these I used mainly for Endo.  The eyeglass lenses are bifocal-the upper half are clear glass the bottom half I believe are 1.75.  The light was able to be plugged into my dental unit.  These have been sitting in a closet for the past 10 years and it is time for them to find a new home. Selling for a very reasonable price.
