Without wasting any time, let’s look at the Surefire UDR Dominator features, pros, and cons so that you can make an informed choice in the end.

Robust construction

The Surefire UDR Dominator flashlight is Surefire’s most potent searchlight/spotlight. It is built for advanced outdoor use; thus, it features the best materials. The body of the flashlight is made of high-strength aerospace aluminum alloy with Mil-Spec hard-anodized finish for durability. This means it will work in all the harsh conditions that you operate without any issue.

State of the art LED

For such a powerful flashlight, it is only okay if it has one of the best-LED technologies on the market. That’s the case with the Surefire UDR Dominator. It is equipped with a virtually indestructible LED emitter, a microprocessor that is regulated to maximize output and runtime.

Precision reflector and coated tempered window

Additionally, it also comes with a precision reflector that creates an extended-range beam. Aside from that, it has a glazed, tempered window that resists impact and thermal shock. All of these work together with the LED to produce a strong and smooth white light beam that reaches far and wide.

Variable output

The Surefire UDR Dominator 2400 lumen flashlight comes with a variable output. You can choose from the lowest 14 lumens to the highest 2400 lumens. Depending on the type of battery that you’re using, you will get the same number of lumens but different runtimes. The lowest lumen has an extended runtime of 54 hours, while the highest lumen has a runtime of 2.5 hours.

Extremely bright light

At a maximum of 2400 Lumens, this is an extremely bright light that is enough to blind you for several minutes if shone in your eyes. That’s why this spotlight is also great as a defensive weapon as it also has a strike bezel for hitting an attacker. The brightest light beam reaches up to 931 meters, which is fantastic.

Fuel gauge (3-color LED indicator)

The battery level indicator will notify you if your battery is full or not during charging. It also shows you the battery status. Green means it is filled up, amber means it is low, and red means it needs charging. The best part about this battery is that it doesn’t heat up even when used on a higher output level for long. This is because it has thermal regulation.

Powered by one Li-ion battery or twelve 123A disposable batteries

Different cells determine different runtimes. If you want the most extended runtime, then you will turn to 123A batteries as they will last for at least 54 hours on 14 low lumens while 30 hours on the same 14 low lumens when powered by Li-ion rechargeable batteries. And for the best runtime on the highest mode, you will still have to use the 123A batteries to give you at least 2.5 hours of use. However, for convenience, you will have to use the Li-ion rechargeable batteries.

Extra-long lanyard

When you’re not using the flashlight, you can securely wrap it around your neck or shoulder using the extra-long strap. Additionally, it has a removable lanyard ring that is held in place by the tail cap and offers the rear sling attachment point. So, you can also attach a sling if you want to.
