Design and Build Quality

This is a military grade torch and its casing is made of aluminum, coated with thick rubber and with high quality plastic switches. Material durability is confirmed by fall resistance of up to 1.5 meters. In addition, the buttons have a rubber cover to prevent water and moisture from getting inside, so the flashlight is IPX-8 certified and waterproof up to 2 meters. Glass protecting LED light is resistant to cracks and scratches and it seems to be made from material similar to one used in smartphones.

A very useful add-on that comes in the box is a holster that can be attached to or backpack or belt with a snap hook. All this makes it an perfect outdoor companion that you can take on a trip out of town, or as the manufacturer suggests – to use as a personal defense tool.

Lighting Performance and Capabilities

Unlike other flashlights in this segment, there is only one very strong LED light emitter. The CREE LED has adjustable illumination of 30 to 1000 lumens and casts a strong, focused light. Thanks to this, the luminous flux can be thrown even up to 268 meters, in a clear air and a moonless night. An additional useful feature is the stroboscope, which is activated by long press on the switch. It emits intermittent light, blinking at a frequency of about several times per second. The strobe can be switched off by pressing and holding the switch again for about 2 seconds. Strobe lights are used as an SOS signal, for example, when you get lost in the wilderness and want to call for help, but your smartphone has no reception. We hope that this is won’t be a frequently used feature, but if you have to use it, it may save your life.

The flashlight feels very comfortable and solid, though it’s quite heavy, mainly due to the high capacity battery. It’s very easy to – turn it on and off with push of a button, and turn the knob to change the intensity of light from 30 to 1000 lumens. To recharge it, plug it into standard USB charger or even laptop, using provided cable.

DM21T is powered by a 2800 mAh Li-ion IMALENT 18650 lithium-ion battery and comes with a USB cable to charge it from the standard smartphone charger. This makes it easy to recharge your flashlight, without replacing the battery. Battery is not built-in, so if necessary, you can replace it in case of damage or loss of performance due with another cell of the same type. The manufacturer has applied reverse polarity protection, so if you insert the battery incorrectly, the flashlight simply won’t turn on.

This powerful battery lasts 1 hour and 45 minutes (for maximum brightness of 1000 lumens) or 80 hours for 30 lumens. With such efficient power supply, you can take your flashlight on a trip outdoors, even if you don’t have access to electricity.
