An important tool in the medical field, the penlight should be versatile and reliable. Although penlights are often taken for granted as a pretty basic tool, you should consider several factors when choosing a new light. In this guide, I will discuss several of these factors and present a roundup of the best medical penlights. Check out my recommendation for the best penlight for nurses at the end of this article.

Here’s a quick list of the Best Penlights for Nurses:

Important Features of a Good Penlight

Medical professionals reach for their trusty penlight frequently. These lightweight tools are used for a variety of everyday applications, from testing pupil dilation to examining ears and mouths to checking out deep wounds. A variety of other uses come up on a daily bases, be it needing a light to check on patients at night or searching the deepest, darkest corner of a desk for a lost item.

Most penlights are very affordable in price, but be wary of prices that are too low to be true – it is important that a penlight is durable enough to stand up to frequent use. Buying one good quality penlight is much more efficient than buying multiple low quality, cheap lights. As a medical professional, consider these factors when searching for the best pen flashlight for your job.

Color Temperature

The light in a penlight is provided by an LED, or light-emitting diode. LED bulbs come in a variety of colors, which can make a difference in the visibility and clarity of the penlight. The color of the light is decided by the energy of the photons that are created by the diode. Color temperature is how the characteristics of the light are described, both in color and on a temperature scale from 1,000 to 10,000 degrees Kelvin (K). The light produced by the LED in a penlight could range from cool or bluish in color (over 4,500 K) to warm or yellowish in color (under 3,000 K).

The color temperature preferred by a medical professional or by a patient may vary. For instance, cool, blue-toned light often appears more crisp and bright to the human eye, while yellow, warm-toned light is less harsh. For the purposes of examination – for instance, illuminating the interior of the mouth – cool-toned, bright light (on the higher end of the Kelvin scale) will illuminate detail well. When examining an eye, a warmer color of light will be less harsh on the eye, increasing patient comfort. Finally, be sure to look for the penlight’s color rendition index (CRI). Lights with higher CRI values show colors more clearly and accurately, while low CRI values indicate that the object will look washed out.

One of the major uses of a penlight in the medical field is for testing the pupils of the eyes for dilation. When choosing a penlight for this purpose, the brightness of the light is incredibly important. If the light is too bright, patients will be blinded; if the light is too dim, it will not be effective in gauging pupil size and eye response. For this reason, many of the best penlights will have multiple brightness settings – another great feature is that the first setting when the light is flipped on is low, reducing likelihood of blinding unsuspecting patients. Brightness will be given in lumens, a unit that in penlights may range from 5 to nearly 200 lumens.

Ease of use

A penlight should be simple and easy to use – this is a tool that is meant to be uncomplicated. While some medical professionals may prefer multiple brightness modes, perhaps only one is necessary in your daily role. In any case, a simple push-button is a good feature to look for in a penlight. While it may be fun to have a penlight that can beam multiple beams of rainbow-colored light, consider ease of use on a daily basis – keep it simple!


It’s a good idea to check out the clip on the penlight to make sure it is good quality. A well-attached metal clip will ensure that your penlight remains conveniently at hand. Plastic clips are more likely to break, causing you to lose your favorite tool in a moment when you may be in need of a light.


Reading reviews can help gauge whether your penlight will be a long-term companion. A long battery life is ideal in a penlight – who wants to have to buy a new light every few months. You may also be interested in finding a penlight with replaceable cells or batteries. These can prove very cost-effective over time and you’ll never have to spend time researching penlight brands again!
