A medical penlight is a portable handheld lighting device used in the medical field by doctors, nurses and paramedics.

It is aimed at facilitating the performance of routine examination of certain areas of the human body that require extra illumination – the eyes, the throat, the nose, and the ears (Source).

All medical professionals need reliable penlight. Hence, it should be bright enough to give the medic a clear insight into the examined area, but not so bright that it blinds the patient.

It should also be durable, yet portable, and affordable. If you are looking for a new medical penlight, start your search with our list of the top five medical penlights.

Best Medical Penlight For Nursing Students

1. Welch Allyn 76600 Halogen Professional Pen Lite

This medical penlight by Welch Allyn is one of the best on the market. With its bright, white halogen light and solid brass body, it is sure to not only be effective but also to last for years.

However, some users may find it a bit too heavy because of its durable and solid brass construction. On the other hand, that just means this model is designed to survive the occasional drops and bumps it could experience and keep working as if nothing has happened.

Warranty Protected

Additionally, with the exception of lamps and batteries, the company will repair or replace any defectively manufactured parts for free, as long as you can prove it wasn’t due to misuse, neglect, damage in shipment or normal wear.


This penlight is not to be used for transillumination as burns could result. The use of this instrument in the presence of flammable anesthetics is strictly forbidden, too. Moreover, note that penlights are not toys and should be kept out of the reach of children.

Reliable On-Off Switch

Notably, its on-off switch is fantastic. You can be sure that this penlight will never turn on accidentally because you need to pull the switch to turn the penlight on. Anyone that borrows it will probably be confused and not ask to borrow it again.

Easy To Use

Likewise, you can activate it one-handedly, which is critical when your other hand is managing the patient’s eyelids.

Reliable Light

Lastly, although the light is slightly uneven, a product of the antique halogen bulb (you can see the reflection of the filament coils), the color is good and true. It is bright enough to elicit a pupil response in most patients. Moreover, it is powered by a pair of AAA batteries that are readily available.


  • Durable metal body
  • Reliable illumination
  • Easy to use


  • Relatively high retail price

However, despite being disposable, this set has an impressive battery life. This is partially due to the difficulty of turning it on by accident, which saves a lot of energy. Although these disposable penlights are not as bright as most other models, they are still bright enough for simple eye checkups and use incandescent light for excellent tissue color rendition.

This is a penlight solution that most nurses will find helpful, though medical doctors may find it a bit dim for their specific needs.

Factors To Consider When Buying A Medical Penlight

If you are in need of the best penlight for doctors, nurses, or any other medical professional, here is what you should bear in mind when shopping around for one of these:


It should preferably be small in size, so that it easily fits in the medical professional’s pocket. Additionally, it should be portable and comfortable to hold.

Different Light Modes

We strongly recommend that you pick up a penlight with an adjustable power option. Usually, these models have three modes of operation: bright, medium, and low.

These devices work like this: a full click turns the device on and off while a half-depth click cycles between high, medium, and low output. Then, a full click returns to light intensity level last used.


If your job demands that you examine dozens, even hundreds of patients a day, then it is advisable that you buy one of the six-pack solutions discussed above. The penlights in the pack are made of durable plastic and, although their performance is slightly below that of their more expensive rivals, they offer excellent value for your money.

On the other hand, if you have a private practice and examine only a few patients a day, then maybe you should pick up a stylish and more presentable model. These models are generally a bit heavier and more expensive, but the quality they offer is second to none. Most of them are made of solid aviation-grade aluminum alloy.


Medics can often find themselves in very harsh and even life-threating circumstances. In many cases, the primary tool that gives them a quick grasp of the patient’s current status is their medical penlight. So, you need to choose your penlight wisely. Pick up one that you can trust no matter when and where you need to use it.

As Doctors and nurses often need to respond to emergency calls and rush to examine patients on site, their medical penlight should be able to resist rain, dust, cold, or hot weather. We encourage you to check if the model you have picked up has some weather resistance before proceeding with the purchase.


The lenses of the medical penlights are made of high-quality optical glass and most of them are pre-focused, which greatly facilitates the process of examination. The frequency of the light emitted by your medical pen depends on the design of its lens. All of the products on our list have well-designed lenses and deliver excellent illumination of the examined area.

The Pupil Gauge

Although many doctors, nurses, or EMTs say they seldom, if ever, need a pupil gauge, we strongly recommend choosing a medical penlight model that has one. Some of the medical penlight models reviewed above have a pupil gauge printed on their side.

Power Efficiency

Most medical penlights are powered by batteries, but some models aren’t very power-efficient despite looking stylish. We recommend that you go for a model that has a great light output and at the same time does not consume too much power.

Manufacturers of some disposable penlights brag that the inbuilt batteries of their devices last so long that you will actually forget that you are using a disposable device.
