The Gerber Infinity Ultra Task is a handy pocket-sized LED torch.

The Gerber Infinity Ultra Task is not a "tactical" light – unless your idea of "tactical" is anything that might help deal with unforeseen needs. When I hear the term "task," that's what I imagine.  I think of those countless times when having a pocket-sized source of illumination would come in handy.

The little Ultra Task is just under three and a quarter inches long.  It weighs just over an ounce empty and draws its power from a simple AA cell.  Waterproof up to ten feet and constructed of machined aluminum, the Ultra Task is smooth except for two rings of knurling (one at the head and one about a quarter of the way down the shaft).  The flattened tail of the light bears a large radiused hole for affixing a split ring for keys (or a lanyard, or whatever you like).

The tail of the light features a large hole for mounting a keyring.

The battery tends to rattle inside the housing of the light until the torch is switched on.  (I wrapped a small piece of electrical tape around my battery to diminish this somewhat.)  Operation is simple twist-on, twist-off using the knurled ring around the head of the light.  Gerber claims the Ultra Task produces "up to" 100 hours of burn time and has an effective range of 30 feet.

The Ultra Task produces a blue-tinted beam from its diode.

The pocket clip is the type of clip you'd find on a pen.  It can be rotated freely around the body and removed completely.  I've found that attaching it just below the knurling keeps it fairly stable, but I would have preferred a permanently installed clip riding high near the diode.

The Task Light does pretty well compared to the NightCutter 5PC.

If you need a keychain- or pocket-sized light and you (like me) favor LED torches, the Ultra Task is a good choice.  The LED is a "lifetime bulb" and the power source is common and inexpensive.  Rugged enough to endure daily carry amongst other pocket accessories, the Ultra Task should serve you well. 

Mine is holding up just fine.
