The CMG Infinity fits the bill if you are looking for a long
lasting, short range task light that can handle a good share
The Infinity's strong-suit is its very long battery life,
and as a result, its LED is not very bright when compared
to other single LED lights designed for high output. If this
is what you are looking for, you can check out the "o4"
The Infinity uses a single AA cell for 41 hours of light.
Batteries are cheap and easy to find. While many people may
not like the dim output, this would serve well in a dark tent
or cave when the eyes have become partially dark adapted,
or for close-up work in other situations.
The exact composition of the "patented circuitry"
inside the Infinity is unknown. Since LEDs run on 3.6 volts
and the light employs only a 1.5 volt AA battery, a step-up
circuit is obviously part of the system.
The Infinity is made entirely of machined aluminum and feels
very sturdy in the hand. The case has sufficient knurling
to make the light very easy to turn on and off. The outside
of the aluminum is anodized to give its outer finish some
durability. Knurling has been added to ease the process of
twisting the light to turn it on and off.
The light is watertight, as advertised, and is able to withstand
drops with no significant effect on operation.
In use, you'll notice that when the light is off the battery
rattles around inside the case. This could easily be fixed
by using a foam battery retainer ring similar to what is found
in the Arc brand of lights. This is really only an annoyance
and has no effect on the operation of the light.
I also noted that the LED was a bit off center in the bezel
of both samples. This is simply a manufacturing slip and has
no real effect on the usefulness of the light.
Personally, I am finding the white Infinity is becoming one
of my personal favorites for walking around inside the house
at night. Its light is adequate for most nighttime tasks
without overwhelming your night vision or waking others.
+ + + Pluses: Very durable, watertight, very long
battery life, easy to find & cheap batteries, recessed
- - - Minuses: A bit large for a single LED light,
battery rattle when off, dim output (not necessarily a bad
thing, depending on your needs)
