The DN70 were provided for testing by Fasttech shop free of charge.
I chose the model for the review, because I’m interested in the format 26650+XHP70. It’s an old but updated 2018 model - now with a black back cover.
Here only photo and short description. Full review with non-English text in my blog
Short resume: very good flashlight with bright and smooth flood light, but with several nuances.
Specifications:
Modes:
Turbo, 3800 lm, 1 h 30 m
Maximum, 2500 lm, 2 h 30 m
Middle, 300 lm, 6 h
Minimum, 20 lm, 50 h
Beam distance: 325 m
Intensity: 26 300 cd
Impact resistant: 1,5 m
Waterproof: IPX8 (2 m)
Packaging
The package was a little dented, but the lamp is completely intact. My post service is a fan of Footbal World Cup and have a little played with a packages. That’s the impression.
Included in the packaging: flashlight, battery (not in photo), soft case, Lanyard, 2 O-rings, micro-USB patchcord, instruction.
Exterior look
Since this year, the lamp comes with a black cover. Looks good, nothing unwanted no attacking edges on the bezel.
Primary feature - OLED display with full information of all modes and restrictions (thermal control and low battery level).
Large square knurling c small notch – very grippy surface.
The flashlight is very compact.
Nitecore EC4SW (MT-G2, 2x18650), Acebeam EC50-III (XHP70.2), Klarus G20 (XHP70), Imalent DN70 (XHP70)
The case is also very compact

Measured dimensions and weight
Length 114,5 mm, Width 32 mm, Max head width 41,5 mm.
Acebeam EC50-III: 123 g
Klarus G20: 132 g
Nitecore EC4SW: 172 g
Ergonomics
Despite the small size is very good in the palm of your hand
The buttons are tight, do not rattle, pressed clearly, but the course is very small and very difficult to find to the touch.
Quite a serious lack of ergonomics - too hard to quickly find buttons.
Controls
Control of 2 buttons is simple, but it could be made even better and easier.
2 buttons
Right: on/off and mode select
Left: turbo mode, strobe modes and show battery voltage
logic is close to Klarus, Manker, Nitecore, Skilhunt, but with differences
Right button:
- from Off by 1 short click run light to last used mode (memory mode),
- from On by 1 short click change mode from Minimum to Maximum,
- from On by 1 long click ( > 0.3 sec) switch off the flashlight
Left button:
- from any mode by 1 short click show on OLED display current battery voltage
- from any mode by 1 long click enable turbo mode 3800 lm, If click < 2 sec, then mode switch back to previous after button released. If click > 2 sec. then mode switched to turbo with no back to previous if button released.
- double click enable strobe, sos and beacon mode. Switch with double click.
No fast access to minimum mode. But after changing battery always start from minimum.
OLED display
All modes show in text or symbols:
modes
turbo
strobe, sos, beacon
In any time can see battery voltage (1 click left button)

Battery
By agreement with the store i recieved flashlight without batteries.
I tested with several difference: long protected batteries not allowed with DN70. Only high drain with flat top and without protection circuit board.
Short length - only one short wide spring in bottom.

Currents by modes
Very short life to Panasonic 26650A if it used in this flashlight
Light: lux
Lux from 1 meter in one point (max)
Not usable as compact search light, because have modes: very low, low and maximum very close to turbo. But good as EDC or city flashlight where primary mode 300 lm and periodically have 3800/2500 lm.
всего.
Runtime
3800 and 2500 only on start have difference. Thermal control makes them the same.
In short distance DN70 output same light as Klarus G20 in mode 3 of 4, but longer.

Non stable level in turbo mode.
On the last chart is not fully calibrated, as well as the lamp is not cooled completely. Brightness fluctuations on all types of batteries, including high drain.
Voltage on battery after low level cut off: 2,86V
Thermal control
One way thermal control change level down from 2500 and 3800 lumens mode to level 900 lm (show in display).
PWM and flicker
PWM - 20 kHz
20 lm
300 lm: 20 kHz with deep of modulation 100%
2500 lm: 20 kHz with deep of modulation ~30%

After thermal control work
Light by stand
White balance = 5000K, tint = 0

Other:
Color temperature deviation.
The average color temperature was approximately 5110К, with with a homogeneous dam in a green shade.
White balance = 5110K, tint = 11R (+11% to red side).
I expected to see a very cold light with 6700К, however, it is only slightly greenish.
Real beams shoot
Scene:
Imalent DN70 2018 in modes. White balance = 5637K, tint = 11R - to compare with more warm lights on only beam distribution.
Beam distribution very good to universal flood light.
Compared to others. WB = 5000K, tint = 0.

Very good smooth and bright light with good quality of light for middle-short distances.
Integrated USB recharge port
Micro USB patch cord from box very short. I detect 1.25A maximum from USB port. Not bad.
End of charge: 4,186 V by external voltmeter.
Ingress protection rating - waterproof
Cover of USB port not have rim on all perimeter!
In Specifications descibed raiting: IPX8 (2 m).
10 minuts in stream
Immediately after end DN70 manually switched to turbo mode. Immediately fogged up the glass from the inside.
IPX8 not confirmed!
Overall
Negative:
- Not a IPX8, maximum IPX4 (rain), or IPX5.
- Not all batteries allowed. Not very negative but not good.
- Not mode with ~900-1000 lm
- Not very low level ~0.5-1 lm
- Light green tint of light
- Not fast access to minimal mode
- Very problem to find byttons without to see on it
Positive:
+ Very good light distribution
- Very compact
- Very good ergonomics by hand and size (not for buttons)
- fast charge (> 1A)
- Good mechanical finishing
- Very interesting display
