LED Pen Flashlights - Features and Specifications

In order to be durable, LED pen flashlights feature a body made of anodized aluminum - some models are made using tough and durable plastic, decreasing the price, but also the flashlights' toughness.

As a light source, LED pen flashlights mostly use a single white LED, although there are models featuring red or green (or some other color) additional LED.

As a power source, AAA batteries are commonly used, although there are very compact models using AAAA batteries, which are sometimes harder to find at local hardware and other stores.

Note: non-rechargeable 1.5V alkaline (shelf life up to 5-7 years) and 1.5V lithium (shelf life up to 20(!) years) batteries may be used interchangeably. Some models operate well when being powered by rechargeable 1.2 NiMH batteries. However, the use of 3.2-3.7 volts rechargeable lithium-ion batteries should be avoided unless explicitly permitted by the flashlight manufacturer.

Some 'thicker' models even use very popular AA batteries.

Light modes usually range from single light mode (On/Off) to more common High and Low, but with some models also featuring SOS, Strobe, Low/Medium/High modes, etc.

Maximum operating time depends on the light mode, but ranges from few hours using the High mode to 10+ hours using Low mode.

Light strength/intensity also depends on the chosen light mode, but pen flashlights easily reach 100 lumens/900 candela, with some models being even much stronger.

Maximum reach depends on the strength/intensity of the light, but also on the presence of adjustable zoom and it varies from 50 to 100m, with some models with adjustable zoom having much longer reach.

Pocket clip helps the user keep the pen flashlight securely in the pocket. Thanks to their dimensions, pen flashlights can be carried in the pockets, backpacks, and everywhere where there is some free space available, making these flashlights an excellent choice as Every Day Carry (EDC) flashlights, but also as a second or even third flashlight for fishermen, hunters, military personnel, for campers, hikers, etc.
