This illuminated hand-held magnifier features a bright LED illumination. SMD LED illumination provides an alternative light source preferred by many people due to its distinctly whiter spectrum and longer useful life. To soften the color of the light, small snap-on filters are included with each magnifier to provide 3 different illumination options. These magnifiers include a comfortable, ergonomic handle with a large ON/Off light switch, a battery compartment that uses high quality springs that makes changing the batteries easier (2 AA batteries included) and a slip-on protective case.
