Why A Penlight?
The best penlight in 2021 could come in handy for many reasons. The people that need a penlight the most are probably doctors and nurses because they use them to check people’s pupils during physicals. Some of the brightest penlights have very high lumens, so doctors and nurses will need to use low brightness to avoid blinding the patients.
Another reason to have a pen flashlight is that it can be great for self-defense and having a flashlight is always a good idea if you are walking around a night. Most of the manufacturers of quality penlights also manufacture tactical flashlights.

A tactical flashlight pen will not be as bright as many of the other flashlights on this site, but they have the added benefit of being easy to conceal since they are as small and look like pens or pencils.
Penlights are great options as EDC flashlights (everyday carry) since they will easily fit in shirt, pants, or even suit pockets. Most LED penlights use AAA batteries because of the thickness and they will not be able to have the same lumens or battery life (run time) as larger, more specialized batteries or even AA battery flashlights.
For non-rechargeable batteries, the Energizer L92 Lithium batteries are the best. If you do not want to deal with rechargeable batteries we recommend seeking out an internally rechargeable penlight, but there are not many.
Many pen sized flashlights are really durable and tough with an aircraft aluminum body, so they can be used as a weapon (kobutan) similar to a tactical pen – but with the added benefit of a blinding light.
What Do Nurses Use A Penlight For?
There are a few things that doctors and nurses check for when they shine a pen sized flashlight in your eye. The first thing that they check for is if the pupils react to the light. If they do not react to the light, it could mean that there has been some sort of brain injury.
The second thing they check for is to see if the pupils act as one, that is if both eyes react the same way even if the light is in only one eye. Your eyes should act as one, if not then the nurse needs to do more tests.
Lastly, nurses look at the color of the whites of the eye and the condition of the blood vessels. There are penlights here that can be used in the medical profession, but we have another article on the best medical penlight if you specifically want a light for the medical field.
The Best Penlight in 2021
Best Penlight with Pen
The Olight O’Pen was probably our favorite penlight of all time and we were really sad when they discontinued it.
What was so great about the O’Pen was that it was designed to look like a real pen. It did not have a real writing pen inside of it but it look really classy and still had a nice flashlight inside of it.
Recently Olight has come out with the O’Pen 2. The O’Pen 2 is a complete redesign and they decided to make it so it actually has a pen inside of it. It is designed to still look like a high quality pen with a slick L-type bolt action to push the pen out. For the light they decided to go with a small 120 max lumen light that runs off of a 3.7 Volt Lithium Polymer Battery that is built into the upper half of the pen.
Since the flashlight and the pen are essentially two separate pieces it allows you to unscrew the two and use the pen and the light separately. Matched with the fact that the O’Pen has 4 brightness modes you will be able to get 10 hours at 5 lumens which would be enough to read with and write with the pen.
