Fenix is a company that exemplifies everything that is good about the flashlight industry. Their innovative, performance driven products use advanced technology to produce some of the most efficient, practical, and highly reliable flashlights on the market. I consider the Fenix PD31 to be one of their best flashlights yet.

Fenix Flashlights: Efficient, Practical, and Reliable

The Fenix PD31 is efficient. One of the most important aspects of flashlights is the output. The PD31 has regulated circuitry that keeps the output of the light constant. “Normal” everyday flashlights get dimmer as the flashlight batteries discharge.

The  PD31 is a practical, versatile flashlight that can be used for almost any use. It has several different brightness settings that give it a lot of versatility. The flashlight also makes use of a good compromise between throw and flood. You will find the light is just as useful when hiking or mountain biking as it is as an EDC flashlight.

The flashlight is also very durable and reliable. The eletrical circuit (known as the driver) uses high quality components that are incorporated in a design that ensures toughness. The CREE XP-G R5 LED lamp that is used is is also tough. Fenix estimates 50,000 hours of life from the bulb. These qualities coupled with the shock and water resistant hard-anodized aircraft aluminum body ensure reliability. You can expect years of faithful and reliable service from your PD31.

The Pros:

  • Cost: This little flashlight has the features and is brighter than flashlights that cost much more. A comparable Surefire with only 200 lumen output can easily cost twice as much.
  • Durability: Shock and water resistant.
  • Intelligent circuitry: The driver has reverse polarity protection coupled with a digitally regulated output.
  • Choice of batteries: The ability to use rechargeable Li-ion 18650 batteries is a nice touch. Those CR123A batteries can get a little costly if you use the flashlight a lot.
  • Size: The size of the Fenix PD31 is almost perfect. It fits in the hand nicely but can still go into your pants pocket without being too bulky or causing discomfort.
  • Ease of use: Easy to use UI (user interface). I think the UI is very intuitive and easy to use.
  • Flexibility: Several different modes of operation.

The Cons:

  • It is a little pricey for some people. On the other hand the Fenix PD31 should offer many years of service negating the need for a replacement flashlight. It is also much cheaper than similar high end flashlights.
  • Some reviewers don’t like the UI. It is a little more tricky than a simple flashlight with just an on – off button switch but I find it easy to use and very intuitive.

What Customers are Saying:

The Fenix PD31 has an overall rating of 4.5 stars out of a possible 5 at the Amazon.com site. Here are excerpts of some of the reviews:
