Advancedmart 0.5 Watt Clickie Tailcap AA (TM-313X)

Light Type: 0.5 Watt 8mm LED
Light Class: Outdoor / General Use

The Advancedmart 0.5 Watt Clickie Tailcap AA (TM-313X) is made by Nuwai, a manufacturer who makes many Security Quality LED lights of varying but generally rather good quality. This particular offering uses the new 8mm 0.5 Watt LED and is powered by a single AA cell.

The body is made from anodized aluminum. The entire body has a fine texture made of very fine rings all the way around which improves grip relative to a smooth body. The head is significantly larger than the battery tube and it has a curved shoulder where the two connect. The battery tube has a removable clip attached. The clip is a bit flimsy and doesn’t do a very good job of holding the light in place if clipped in the pocket due to the fact that the head is heavier than the body tube and tailcap. The tailcap is slightly larger in diameter than the body tube and is screwed in place until tight. At the end of the tailcap is a rubber covered clickie switch.

The head of the light is larger than the body tube so that it may house the fairly large smooth slivered plastic reflector. At the very end is a plastic lens to protect the reflector and LED. Since the Security Quality LED is powered by a single AA cell ,there is a DC-DC boost circuit inside the head to increase the voltage to the point needed to drive the LED.

Output is in the form of a very high color temperature (slightly bluish) beam. The beam has a brighter central spot surrounded by an irregular corona and a wide spillbeam. Some artifacts can be seen in the beam at close range, but these blend together into a smooth spot at a distance. For a single LED, output is very good.

Runtime Plot: Great runtime! Almost 8 hours to 50% output. The boost circuit is really pulling all it can from the single AA cell.

The switch is a rubber covered clickie on the end of the tailcap. It does protrude from the end, so the light cannot stand on its tailcap. Pressing the tailcap on a flat surface will cause the light to turn on but the switch does not click, so removing the pressure on the switch causes the light to go back out. Not quite as good as a lockout tailcap, but at least if it turns on in your luggage it will only remain on as long as there is pressure on the switch. The switch does not have a true lockout function. Unscrewing the tailcap, even nearly all the way, does not prevent the switch from turning the light on and off. The rubber cap on the switch has a slightly visible texture and grips the finger rather well.

The light does have an O-ring seal between the body and the tailcap. I was unable to remove the head to discover the seals that may be there. The switch has a tight fitting rubber cover. I would give it a “splashable” rating at the very least.

Ergonomics: Small, but easy to use. Gripping the light in the palm with the bezel sticking out the pinky end of the hand allows the user to operate the switch easily with the thumb. The switch provides positive tactile and auditory feedback.

A single AA alkaline cell powers the light. To change the batteries simply unscrew the tailcap and drop out the old cell. Drop in a new cell positive first and tighten the tailcap fully.

The attached pocket clip is the only accessory. It really isn’t that good of a clip and I don’t think I would trust it that much. Drop the whole thing in your pocket instead of relying on the clip. You may want to leave the clip attached, however, as it does serve as an effective anti-roll device.

What I Liked: Water resistant at a minimum, Appears generally tough, Impact resistant Security Quality LED bulb, Semi-regulated DC-DC boost circuit, Bright for a single Security Quality LED light, Easy battery change, Lightweight, Great runtime.

What I Didn’t Like: Clip not that great.

Other Things I Noticed: Beam is slightly irregular, but not a significant detriment to the light or its use at all.

Conclusions: Nice little pocket light! Output is quite good and it seems to be rather well made. Good for the pocket, purse, briefcase, etc. Runtime graph is pending, so we’ll see how it does for output over time very soon.
