Best Penlights in 2021: Professional Precision
A penlight is a very versatile, small flashlight. As its name suggests, penlights are shaped like pens. While there are other small flashlight types for everyday carry, penlights are unique in that they easily fit into a shirt pocket or clip onto a cap. Thus, they are a go-to lighting implement for a few professions, particularly doctors, nurses, first responders, and tradespeople.
If you’ve come here looking for a penlight for your job, let me quickly note that you’ll find two categories of penlights, and that should quickly guide your purchase decision.
Medical professionals tend to use penlights to check for pupil dilation or during exams. As such, penlights for nurses, doctors, or medical students don’t need the beam to project nearly as far from the light as users such as police, EMTs, mechanics, or people recreating outdoors. For medical professionals, weight, simplicity of use, and appropriate brightness are important factors to consider.
For outdoors or trades use, durability, waterproofness, and higher lumen output set good penlight choices apart from others. And let’s not forget, one of the coolest features of some penlights for trade and outdoors use is a reversible clip that allows you to attach it to a baseball cap and wear it like a headlamp.
Because these two different use cases require different lights, I note below the primary uses of the listed lights.
We’ve compiled this list of the most adept, versatile, best penlights to get you out of the proverbial dark.
The Best Penlight
The Streamlight 88033 is a tactical flashlight/penlight combination that is built to last. It is perfect for military and law enforcement officials and has a push-button tail switch to easily alter between programmable modes whenever you need it.

It has a variable light output and a strobing function, both of which are useful for law enforcement or military applications. Its casing is robust and durable and can survive being dropped and submerged in water, even for days at a time.

It’s great for inspecting sensitive electronics, working on mechanical projects in dimly-lit spaces, to for outdoor use. Having used this one a lot, I love that it’s easy to recharge with any micro-USB cable. It also has a reversible clip to attach it to any baseball hat, a great and useful feature.
The charge port is hidden to protect it from the elements, and the outer casing is easy to grip and hugely robust to withstand damage such as drops or being driven over.

Penlight Buying Guide
Features To Look For In A Penlight
If you are planning on investing in a new penlight, we recommend you quickly review our priority list below for the key features worth considering.
How Will You Use It? This is the first factor to consider when buying a penlight. The needs of an electrician are very different from the needs of a nurse, so considering how you'll use the light most of the time is critical.
Convenience - The whole purpose of having a penlight as opposed to a traditional and bulkier flashlight is ease to use and portability. Your penlight should be sized so that it can easily fit into a backpack, a trouser pocket, or even a front shirt pocket. Check out the weight of each light, and consider how it'll factor into your use. Keep in mind that a pocket clip is very helpful, and in some cases you can spin it to clip backward onto a hat brim.
Construction - Consider the build of the product, and if it fits your needs. If you are using a penlight either because you're an outdoor enthusiast or you require one in the line of duty, then clearly it needs to be reliable and robust. In those cases, look for water-resistant, metal construction. Likewise, if you intend to use it outdoors, it pays to ensure that your penlight is also waterproof and shockproof. Check the waterproof and shock ratings on each light, as they vary from fully submersible to splash-resistant.
Ease Of Use - This again returns to the intended purpose. For those in law enforcement, a strobe feature can be very useful. But a strobe is detrimental to medical professionals and could cause problems for patients. So consider the features of each light and make sure they fit your needs.
Runtime - Runtime varies a lot from light to light, but tends to rely on the type of battery, light output, and type of LED. For those who will use low-power outputs primarily (think medical professionals), runtimes should be many hours. On the other side of the coin, powerful penlights will usually only run at high for an hour or less before requiring battery changes. For those who need a lot of power for longer runtimes, a penlight is probably not the best choice, so check out these more powerful flashlights here.
Battery - Some batteries are harder to locate than others but for the most part, the range of penlights we've recommended run on readily sourced batteries, primarily AA and AAA. The runtime, brightness and also reliability will affect the battery life and source and if this is the only means of powering your particular penlight, then make sure that you have backup supply close by.
Q: What's the difference between a penlight and a tactical flashlight?
A: When you were doing your research, you probably came across both penlights and tactical lights. The term "penlight" refers to the shape of the torch. And there are plenty of tactical penlights. Most tactical lights have a lot of power output, as well as a strobing feature to disorient subjects in the field. There are also many non-tactical penlights that do not have strobing features and have less power. These are more suitable to use by mechanics, carpenters, electricians, and medical professionals. There is a bit of an overlap and both make exceptionally reliable light sources.
