A compact keychain flashlight for everyday carry, combining minimal dimensions with simple, reliable operation. Powered by a single AAA battery and activated without buttons — just twist the head.
Activation runs through a threaded joint: tightening the head closes the contact and turns on the LED, loosening it turns the light off. This mechanism removes any controls that could trigger accidentally in a pocket or bag. Output comes from a Philips LUXEON TX LED paired with a PMMA TIR lens that focuses the beam into a compact, even pattern. The housing is machined aluminum with an anodized (Type III Hardcoat) finish for increased scratch and corrosion resistance.
Key advantages:
- Compact size and weight — virtually unnoticeable on a keyring
- Button-free twist activation — prevents accidental activation in a pocket or bag
- Dust and water resistance rated IPX8
- Impact resistance up to 1.5 m
- Powered by a widely available AAA battery (alkaline or rechargeable NiMH)
