Maybe the Most Powerful Keychain Flashlight
You must have used considerable keychain lights but not satisfied with their low brightness and convenience. Now you could choose this strong UltraTac K18. It will give you a big surprise!

Support 10440 Battery, Awesome BRIGHT
Just less than 3" (2.95 inches) and weight 0.49oz (14g), you don't even notice that it's there. Thanks to the innovative circuit, K18 is compatible with a variety of batteries: 1.5V Alkaline/Lithium AAA, 1.2V Ni-MH AAA and 3.7V Li-ion 10440 which brings you really amazing MAX 370 lm.
3 Light Levels plus Strobe, Stainless Steel Side Button Switch
Uses a Cree XP-G2 S2 LED and supports 3 levels: Low- Mid- High, and hidden Strobe (Double click activate it). BIG SURPRISE again, most keychain lights have no a strobe mode. The lowest level (4lm with AAA) boasts super long 40 hours, great for reading comfortably in bed without spoiling your night vision or disturbing others. And the brightest level (370 lm with 10440) is the equivalent of a mini-searchlight. And the front side button switch provides convenient one-handed operation.

DTP Copper MCPCB, Faster Heat Dissipation
The better Direct Thermal Path (DTP) Copper MCPCB provides excellent heat dissipation to ensure the best performance. And the body is made from high strength aerospace aluminum alloy with premium type HAIII hard-anodized anti-abrasive finish.

Stainless Reversible Clips
With high quality detachable stainless steel reversible clip, you can put it in pocket or reverse to fasten to hat as a hat lamp.
