This is the infrared (IR) CREE LED version of the TZ980 lights. In order to use the IR LED TZ980, you MUST have night vision gear. The light beam is invisible to the naked eye. For varmint hunting this is ideal as the animals can not see the light at all, but with night vision gear they will be lit up full daylight! All TZ lights are sold as a full kit. Everything you need is included with the package. TZ980 Infrared LED light, picatinny rail mount, quick release mount, wireless remote pressure switch, and batteries (2 CR123A for the light, 1 CR1632 for the remote). Also included is an adapter when using the two CR123A batteries.
