Why use a penlight?

Medical Practitioner– If you’re a doctor or a nurse, then you come across numerous situations when you want to examine your patient under a bright light. Mainly, penlight is most used for ‘pupil test’ which is a technique of determining the response of a patient’s pupil to light. Moreover, penlight is used also for checking the mouth and throat for infections and sores.

Mechanics and Electricians– If your job involves checking engines and wires, then pen light is one of the most useful devices you can possess. When you need to check the parts on the interior of engines and devices, a penlight can assist you in a brilliant way by allowing you to illuminate that particular area with a bright light.

Other uses: Apart from specialized lighting needs, penlight can be useful for general purpose uses as well. Penlight can serve as great self-protection bright when walking around in the night. Since most of the penlight manufacturers are also the makers of tactical flashlights, you can even find penlights that can be used as defense equipment.


Things to consider before buying a pen light

Penlight flashlights are indeed versatile and sleek devices. With a wide range of functionality and ease of use, they can lighten one’s life if used wisely. As there are extensive selections of manufacturers and brands in the market for pen lights, it is always necessary to do some research and learn about what to look for when purchasing one that best meets your needs.

Here, we have explored some features that you might want to consider before deciding which pen light to buy:

Lumens/ Light Intensity

In lay terms, Lumens is defined as a measure of the total amount of visible light to the human eye illuminated from a lamp/bulb or any other light source. Bright lamps have a higher lumen rating. You should keep in mind the purpose of your pen light use. If you want to use it for checking the eyes of your patients, you need to consider the lumen range that might not hurt patients with unnecessary intensity. For ease of selection, you may use penlights in the range starting from 80 all the way up to 160 lumens.

Batteries/ Run Time

One of the most crucial parts about choosing a pen light is dependent on the battery it uses. Mostly, pen lights use AA or AAA type batteries as these batteries are slim and don’t add too much weight. Depending on your budget and need, you can choose between either the traditional batteries or high performing Lithium cells. Though Lithium cells are a bit costly, they have enhanced performance with longer run time and brighter light outputs.

Size and Shape

Penlights are designed to fit easily in your breast pocket or external pen pocket bag so that you can carry it around. Usually, the perfect size for a pen light is the one that fits right in your hand while using and has built tough enough to match the lighting necessities. Longer pen lights can have space for additional batteries and hence more power and runtime.

Switch Types

Penlights are devices made for the convenience of users. Needless to say, the ease of operation is something dependent on the type of on/off switch it uses. Generally, there are following different types of switches:

  • Tail Click: It is convenient for one-handed operation. Since the switch is positioned at the tail, it may sometimes cause accidental activation. It is an option for those who need quick on/off.
  • Twist Top: This type of switch is the most common on keychain lights. This is a two-handed operation where you twist the head of the light in clockwise/counterclockwise fashion to turn it on/off. Twist Top type pen lights are best for those who need stable lighting and don’t want to bother about accidental switching.
  • Side Click: This system involves a thumb-forward grip. The switch is on the side of the body, and it best fits for outdoor use.


Indeed, choosing the best penlight is always a bit of a dilemma as there are varieties of options. Depending on whether you are a professional or just want it for personal use, you should choose your penlight accordingly. After all, the one that best suits your needs and budget is the one that you should buy.
