    I rarely give 5 star reviews to anything but, as a general, everyday light, this unit deserves it. I’ve had this light for only about 8 months and I reserve the right to change my mind. A number of manufacturers have tried the beam focusing concept with fair to dismal results. With consideration to the focusing aspect, I would give this unit 4 of 5 stars; it’s probably the best you can achieve in this impossible compromise. At the narrow angle end, the beam could be tighter and “reach” further with its 350 lumens but there is a fair amount of loss to peripheral wash. As a general purpose light, this peripheral illumination may actually be a plus. At the wide angle end, the beam is quite wide and wonderfully even and without artifacts. Construction is typical Fenix: Waterproof, durable, fair to good wrist lanyard and belt case, etc and worth 4 stars. Considering the whole package, this is a 5 star light and, at half the size and weight, may replace my Surefire Ultra as my everyday light.

    I bought this flashlight because I had a friend who was going to a third world country to build schools for poor families. I was going to lend him one of my super powered flashlights that used 18650 or CR123 but then I would have to let him borrow my battery charger. He didn’t have extra space in his luggage and didn’t know if he would have electricity where he was housed.

    That’s when I did research and found this light. It uses two AA batteries, you can find these anywhere in the world. They’re cheap and readily available. This light is perfect for someone like my friend, who wants a versatile light: focus-able beam from spotlight to floodlight, 4 lumen modes, and batteries you can buy cheaply anywhere. Some zoom flashlights are horrible, the light isn’t spread nicely and doesn’t give you even usable light when you need to work in the dark. This bulb and reflector gives you a nice even spread and gives you beautiful usable light for any situation.

    Fenix is top quality, so it’s perfect for expeditions. Fenix also has a great warranty too.

    I was excited to try the FD20 for the focusing feature. My other three Fenix lights have a fixed beam.

    My only concern was that this light uses two AA batteries and is not rechargeable. My other lights charge via USB or rechargeable batteries.

    As a Home Inspector, I used the light for short periods of time to inspect areas of the home such as attics, crawl spaces, and other poorly lit areas. I use it to assist in taking pictures and identifying problems in the home I am inspecting. I also use the light outside of work when walking the dog at night. I live in Florida adjacent to a County Park and many times encounter several types of wildlife when walking the dog including coyotes, armadillos, racoons, possums, and even the occasional alligator. The dog will alert to these animals in the dark well before I can see them. I can use the light to light up the street and then focus in to see what the dog has alerted to.

    As for my concern about the light night not being rechargeable, it’s been over three weeks and it is still going strong.

    What I love about the light:

    Focused Beam: The ability to focus the light beam has been a great feature. When doing home inspections, I can focus in on parts of the attic or areas of concern, take a picture and have it highlighted with no extra work needed when adding the pictures to my reports.

    Adjustable beam strength: The adjustable beam strength allows me to take pictures with the right amount of light to add great pictures in my inspection reports
    Single button control: The most impressive feature for me. The FD20 has a single button for on/off and for adjusting the strength of the beam located at the rear of the light. One click turns the light on or off. To change the strength of the beam, a gentle tap will do. Love this feature.

    Compact Size: The compact size works great for me. While inspecting homes, I carry several types of testing equipment, the slim design does not take up much space in my pockets.

    Durability: So far after several drops on all types of material the light is holding up like a champ. Just like my other three Fenix lights.
