With the development over the past few years of high output LEDs, there has been a race among flashlight makers to produce units with greater lumen output. While that is all well and good, manufacturers have often overlooked that there was still a need for a penlight suitable for pocket or purse.

In order to meet the demand for a reliable penlight and eliminate the need for replacement batteries, Coast introduced the A8R. This light is rechargeable via AC, DC or USB ports. In other words, whether you are at home or in the field, you can probably find a charging source for this penlight.

The A8R has an output of 12 lumens and a run time of 1.25 hours, which is more than adequate for penlight applications. In fact, we have this one in the console tray of our truck, ready for use or recharging, as required. Simply slip the charging cap over the head of the penlight and the light glows red while charging and turns green when charging is complete. No guesswork is required.

The A8R is not a toy or a big box store special. It is the smallest and lightest rechargeable penlight on the market. It is fair to say that, ounce-for-ounce, the A8R is the best on the market. We are keeping this one and plan on ordering another for the house.
