The Gemolight is a state of the art identification tool, featuring nine different light settings:

Daylight (bright & dim)
Incandescent (bright & dim)
Infrared light (bright & dim)
Longwave UV 395 nm
Midwave UV 365 nm
Blue light

Includes two focusing cones to pinpoint light. Each cone, rather than using the threads, has precisely measured O-rings to snap into place and the opening measures approximately 8mm. Complete with built-in belt clip and a ruler on the body.

The battery is rechargeable and a standard USB cord is included. Expected lifetime of 10 years when charging every 3 days.
