ProTac 1AAA Penlight

Compact LED Light Without Compromising Power

Known for the extreme durability and long-lasting quality, the Streamlight 1AAA Penlight is the perfect EDC flashlight for you. Measuring in at an incredibly light 1.3 ounces you will not even know the light is in your pocket! Even with the minimal weight the 1AAA Penlight can put out an astounding 115 Lumens - perfect for your spur of the moment lighting needs. As of 2015, the NTOA has given the ProTac 1AAA Penlight a Member Tested and Recommended certification.

Moreover, the ProTac 1AAA Penlight can run on a single Alkaline or a single Lithium battery. When using the Lithium battery, your run times are almost doubled and you can use the ProTac 1AAA up to 23 hours! However, if you decide to use an everyday Alkaline battery, that is included with the flashlight, you can still use your flashlight up to 17 hours before needing a replacement! These exceptional run times and the capability of using two types of batteries make the ProTac 1AAA Penlight the perfect addition for your EDC collection.

Very professional and answered all my questions...

I find this product very helpful and cost effective.

Excellent "penlight" - improved over MicroStream.
September 7, 2019
Purchased this light (x3) as a component of our family's emergency packs.

The light is very lightweight when equipped with a 1.5V lithium primary, and its included accessories of a pocket clip (reversible) and lanyard gives plenty of possibilities for carry that may be necessary/convenient during an emergency.

The increase in output - as well as selectable output - versus the MicroStream (which I also have) not only makes for excellent utility, but in my view justifies the jump in cost.

As another reviewer noted, the reversible clip is a bit tight on typical baseball cap bills. The included holster is also of limited value both in that it only allows for one mounting method/orientation as well as is very tight.
So. Cal.
Better than I expected but could be even better

I like the fact that this light is a clickie as opposed to a twist-on. Battery life is as advertised. The center beam gradually blends into the spill light, so you won't have a very bright area in the center and then an overly noticeable drop-off into the spill light area. This makes the beam very practical for most tasks where a 1AAA torch may be used. Much more of a floody than it is a thrower. The 2-way clip is nice but the end that opens to attach to the bill of a BB cap is very narrow and you will have to use two hands to pry that end of the clip open wide enough to slide the bill of the cap into. The clip on the 1L-1AA has a better/larger opening for this purpose. The clip is very tight. I tried to spin it and it scratched the body, so beware. I'm sure removing it and putting it back on would be even tougher. Lastly, the clickie is on the firmer side and the torch being a bit slippery and so small to begin with, it makes it a little difficult to get a good grip to turn it on with one hand. I wrapped a piece of grippy tape around the body of the torch where it is smooth between the cooling fins and the clip. That helped a lot.

great light

Carry this light in my pocket every day. I have both the ProTac and the microstream and the difference in the brightness is well worth the difference in the price of the two lights.

Have several of these ProTac 1AAA flashlights and this upgraded model has more lumens. I'm sure it will perform well.
