Short Description:

The Infinity Ultra is a new iteration of the classic Infinity made by by CMG Equipment (Course Made Good). It has the same basic body as the regular infinity, but is significantly brighter. It is intended for the campers and hikers who find the original Infinity appealing but would like a light in the same package that provides more illumination.

The body of the Infinity Ultra is machined anodized aircraft aluminum. The anodize finish is dark green. The head of the light is knurled for grip and the body has a ring of knurling 5/16" wide about 1/2" from the front. The end of the Infinity Ultra has a thick tab that is drilled for the insertion of a lanyard (included). A metal pen-like clip is also included. The head is shaped so that the LED is recessed in the front of the unit and is surrounded by a cone of metal that serves as a reflector of sorts. The head of the light is sealed with an O-ring which makes it waterproof to 30 feet.

The light is produced by a single white LED. The reflector area of the head is anodized the same color as the rest of the body. The beam is a smooth flood with a slight "X" shaped pattern in the very center. The beam color is slightly bluish in the center, fading to a very slightly greenish-yellow white light.

Twist the bezel for on/off. Tighten for on, loosen for off. Unscrewing the head completely reveals the battery compartment.

Like its predecessor, the Infinity Ultra uses a single AA battery (not included). Its battery life is advertised as 25 hours at "peak brightness".

Included in the package are a lanyard and a pocket clip.

Reviewer's Impressions:

The CMG Infinity Ultra is a great "High Output" option that compliments but doesn't replace the original Infinity. A compact, convenient light with excellent runtime and bright output. If you found the original Infinity to be too dim for your purposes, but you liked the form factor, you'll love the Ultra.

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. The LED is very deeply recessed and it would be very difficult to damage it. Overall quality is excellent.

Output is also very good for a single LED light. The Ultra, like the standard Infinity, has a step-up circuit built into the head of the light. The difference is that the Ultra is tuned to put out much more light (28 Lux vs. 6 Lux on new batteries) at the cost of battery life. The Ultra is advertised as providing light for 25 hours as opposed to the 40 hours achieved by the original Infinity.

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 head, drop out the old battery, and place a new battery in negative-side first. Screw the head back on and you are ready to go. A battery change could be easily accomplished in the dark. The Ultra can be used with Lithium AA cells for brighter output (32 Lux) and greater resistance to cold.

Water resistance is very good, with the light being able to withstand 30' of depth. 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. For camping or hiking I think I would prefer the Ultra over the original Infinity simply because the extra light output would be useful in more situations. Installing a Lithium AA (10 year shelf life) would help make the Ultra a perfect addition to a "bugout bag".

Improvements: The only possible improvements I can envision would be designing the light so that it can stand on it's butt end and giving it a Level 3 Hard Anodize finish for durability. Other than that, it's excellent.
