Imalent DT70 Review

The Imalent DT70 or “Flood King” is a compact, handheld flashlight that hold 4 dedomed XHP70 emitters in 4 partially fused reflectors with a claimed output of 16000 lumens. It’s powered by 4 – 18650 batteries that are provided and is recharged via a micro USB port. The DT70 has a digital display for battery level as well as lumen setting.

The DT70 comes in this nice box.

When you insert the battery and twist the head on the body, the display briefly turns on with the IMALENT word, before shutting down. When you change levels, the output will appear briefly on the display.

Press the Right switch to turn the light on at the last used mode between: Low (80 lumens), medium (1000 lumens), High (8000 lumens). To cycle between these 4 modes, press once the right switch.

The turbo (16000 lumens) mode can be activated either with a momentary on (keeping pressed the left switch), or constant on (keep pressed the left switch for 2 seconds). If you release the left switch within 2 seconds, the light will return to the previous mode. In turbo mode, once the internal temperature reaches 50°, the OVERHEAT word will appear on the display, blinking, and shortly after, the output will be automatically lowered. When the constant on turbo is activated, click once the right switch to return to the previous mode.

A double click of the left switch activates strobe, another double click a SOS, another one for the Beacon. If you press once the left switch, the display will tell you the voltage of the cells (works when the light is either on or off)

When charging the light, the display will remain on and show the level of the charge and you can always press the left switch to get a read of the voltage.

The DT70 is well built and finished. It’s the brightest flashlight I’ve ever used and did a great job lighting up cave environments where there are zero additional light sources, filling the space with consistent smooth lighting with great throw.

When using the DT70 on the 8,000 or 16,000 lumen setting, the light becomes hot in short order though completely usable via its handle which stays cool. The readout screen is fantastic in helping to know your LED setting and voltage.

The lighting levels are well spaced at 80, 1000, 8000, and finally 16000 lumens (13,000+).

I love the integrated charge via USB cable so I don’t have to remove the batteries after every trip and can simply use a standard USB cable to recharge.

The light would benefit from having a lanyard hole… considering the lights cost, it would be great in preventing drops in outdoor underground environments.

16,000 Lumen Setting

Where the light really “shined”, was in long dark passages. I was able to effectively light passages and take photos via smartphone camera that would usually require a DSLR w/ flash and remote flashes.

I highly recommend this light to anyway who enjoys cave photography and prefers the use of point and shoot or smartphone camera’s.
