This Lumenok is:

Lightweight

It adds only a few grains to the weight of the archer's nock, depending upon model selected. Select from the following model nocks: Carbon Express TCX nock, the Gold tip GT nock, the Super Uni-nock and the Easton X-nock for small diameter carbon. Little effect to arrow flight is detectable.

Self Contained

The Lumenok requires no magnets, no glue; it contains no switch or any other moving parts. There is nothing to attach to your bow, or glue into your arrow to make it work.

Fits most popular arrows

That includes any arrow that accepts a Carbon Express TCX Nock, Bohning Signature Nock, Easton Super Uni-nock, Gold Tip GT nock, or PSE nock. The The Lumenok-X is available for Easton Axis, Superslims and Beamen Black Max arrows

Easy To Use

Just remove the original nocks from your arrows and insert the Lumenok. When the nock is fully seated against the electrically conductive end of the carbon or aluminum arrow shaft, the Lumenok lights. Wiggling the nock back and forth in the shaft breaks electrical contact between the arrow shaft and the Lumenok, causing the light to go off. At this point the archer can put the Lumenok equipped arrow in his quiver and forget about it. It will automatically be activated upon release of the arrow when shot, allowing the archer to more easily follow the flight of his arrow. The Lumenok will remain lit for up to 40 hours or until retrieved and is turned off by wiggling it back and forth. These nocks will operate hundreds of times.
