This is a great little flashlight.  The Body is Black, Anodized Aluminum.  The Head and Instant On/Momentary On button are Brass.

With this model, the light can be turned on instantly with a push button on the base of the light or can be turned on to stay on by twisting the head of the light.

The head has 3 Ultra Power LEDs that produce a bright, snow white light that lasts and lasts.  The lights are shock and water resistant.

It is a great match to Bark River's LE versions of their excellent knives.  This light will fit in the firesteel loop on BRKT sheaths and in the KSF Pocket Sheath.  It is larger in diameter than an army firesteel, so the leather on the sheaths must be stretched a little, but it works quite well.
