The Gerber Infinity Ultra is a compact, convenient
light with excellent runtime and bright output. They
have taken the original
CMG Infinity Ultra (Gerber acquired CMG) and have
given it a style to match their other aluminum lights.
The body of the Gerber Infinity Ultra sports a gorgeous
Type II anodized matte finish. The surface appears to
have a very slight granularity to it which makes it look
very modern and sleek. Around the head and tail are ridges
raised above the curved surface which facilitate grip
and add to the overall appearance. From a durability standpoint,
the Infinity Ultra can take almost anything you can throw
at it. It is very strong and only suffers from minor surface
damage when abused.
Inside the head is the 5mm LED and step-up circuit.
The LED is very deeply recessed and it would be very
difficult to damage it.
Output is in the form of a very pleasing white light.
The beam itself consists of a roundish hotspot with
some typical LED artifacts in the center, surrounded
by a round spillbeam.
The switch is the tailcap. Twist for on and off. There
is also a lanyard hole in the tailcap for convenience.
Several readers have reported to me that if you turn
the tailcap until it just turns off you can use the
tailcap switch as a momentary switch by pressing in
on it with your thumb. Sure enough, it works! Thanks
Beam quality is the same as nearly every other single
white LED light. No issues there. Slightly bluish center
as to be expected.
Changing the battery is very simple. Unscrew the tail,
drop out the old battery, and place a new battery in
positive-side first. Screw the tail back on and you
are ready to go. A battery change could be easily accomplished
in the dark. The Ultra appears to be able to accept
Lithium AA cells for brighter output and greater resistance
completed with Rayovac brand alkaline battery. More
information on runtime plots is available HERE.
Water resistance is very good, with the light being
able to withstand 10' of depth (advertised). The Ultra
is equally at home whether you are hiking, camping,
backpacking, canoeing, kayaking, or white water rafting.
I think it is important to note that unless you are
of a large built, this light is a little big for everyday
carry in the pants pockets.
What I Liked: Watertight, Tough/impact resistant,
Long battery life, Easy battery change, Lightweight
What I Didn't Like:
Other Things I Noticed: Removing
the clip marks up the surface of the light pretty badly.
Conclusions: Very good little pocket
light. The new finish is very nice and the output is
about the same as the original CMG version. Not so much
an improvement over the original CMG version as much
as a change in style.
