Imalent LD70 EDC flashlight review: 4000 LUMENS
Imalent is a well-known brand for its innovative products which are always pushing the boundaries
One of their latest products is the LD70. It is a keychain-sized flashlight with an XHP70.2 emitter!
This one, however, is quite unique because most keychain-sized flashlights use standard 3V LED Emitters like the Cree XPL-HI or equivalent. Imalent pushed the boundaries again, something Imalent is well known for, because this one has a 6V emitter with a very high output of 4000 Lm. It also includes a built-in OLED display to indicate the battery voltage and the selected Lumen output, magnetic USB charging, and an E-switch!
Now, that's what I call unique and pushing the boundaries. No one did all that in a small light, like this, before!
It is powered by one built-in (high drain) 1100mAh 18350 Li-ion battery and is small enough to fit comfortably in your pocket.
With its big metal tail switch, the LD70 allows users to quickly switch between 5 brightness levels and direct access to Turbo.
All these features plus the magnetic USB charging makes the LD70 an unmatched choice!
What you'll get:
Ýou can really see the attention to detail Imalent has spent on the packaging. It uses firm cardboard and beautiful, fully printed packaging. There is a thinner outer cardboard packing, which you have to slide off to reveal the package that holds the light.
To open that, you have to unfold the box, it is no traditional box, very neatly designed.
Inside you will find an Imalent card, below that the user manual and underneath the LD70 firmly held by sturdy black foam.
There are more accessories packed underneath the black foam. Once you have taken it out, you will find a sealed plastic bag with a lanyard and the magnetic USB (Type A) charging cable.

Handling of the light
The light itself feels very unusual, very techy as if you are holding an item or relic of star wars. Imalent claims it to be a keychain-sized flashlight but is slightly too large for that. However, handling of the light is very good due to the big metal button which operates the E-switch that gives very positive feedback, clicking it.
It is very comfortable to hold due to its size and it fits my palms perfectly. Due to its somewhat square-ish design it will not roll and tail standing is possible.
Build Quality, knurling, threads, and anodization
As earlier mentioned, it does not have a traditional knurling, the aluminium light is square shaped with rounded corners. There is a smooth outer tube wrapped around the inner tube/light with cutouts and the Imalent engraving. It is not a traditional shaped light, Imalent has really put some effort in this lights design to make it very unique.
More traditional people might want to avoid this one, but more progressive people might enjoy this unique light with a renewed design. Personally i had to get used to it, but after a week or 2 i can really see the effort which has been put in this light so am more forgiving and i started to like it
Anodisation seems to be very good, it does not show flaws or marks after a little abuse. Usually i discuss the threads as well, but since this light does not come with a removable cell there is no need to discuss that because it just simply doesnt have any!
Last but not least, the lanyard ring, well what to say about it? it’s good!
LEDs, Lens, Bezel, and Reflector
The Imalent LD70 is equipped with a single XPH70.2 LED. Imalent does not state the color tint but it is on the neutral to cool side, and I would guess around 5500K.
The light uses a reflector that has a very light Orange Peel finish, which results in a very nice uniform floody beam. Due to its design, it is not possible to disassemble the light easily, something I often like to do when reviewing a flashlight. So, unfortunately, I can only talk about the outside. The bezel has a blue PVD coated color and the head is completely smooth without any crenelations.
The most important thing about the flashlight is the beam. And if I have to describe this in one word? Flood!
It has a tremendous output for such a small light, literally, everything will be lit. However, it is not a thrower, the light won’t reach as far a distance as the Noctigon KR4. Please take a look at the comparison images below.
One thing I noticed when whitewall hunting, it produces the typical Cree XHP70.2 rainbow corona.
Driver & User Interface:
- Press and hold: Cycle the ‘Normal” modes. When the flashlight is on, press and hold the power switch button, it will cycle from 20lm- 200lm-900lm-2000lm, release the power switch button will save the needed output level
- Single-click: to last used mode (mode memory)
- Double click: Turbo
- Triple-click: back to mode before activating Turbo
- 4 clicks: Lockout mode
- Half-press: Cycle through the different modes
- Single-click: Turns the light off
- Double click: Turbo
- Triple-click: (OLED display will switch to battery voltage indication or Lm output indication (depending on actual displayed status)
- 4 clicks: N/A
- The flashlight will remember the brightness that was previously used. When you turn the flashlight on, it will go back to the last used mode. (Turbo and strobe without memory)
Blinky modes menu:
- Strobe mode can only be reached from the Turbo mode. When in Turbo mode, double click the switch to activate Strobe. Slightly press the power switch button to exit Strobe mode.
Low battery warning:
- With the flashlight on; When the voltage is lower than 3.1V, the battery symbol on the OLED display will flash 8 times per 30 seconds.
- With the flashlight turned off, quickly press the power switch button four times to activate the lockout mode. Repeat to deactivate.
- One funny thing is that the OLED display, when the lockout mode is activated, will show a locked padlock icon when unlocking it will show an unlocked padlock icon! This is especially useful when you question yourself why the light doesn't turn on.
- High efficiency constant current circuit will maintain constant brightness
- Press the power switch button three times to check battery voltage.
- When using the highest output modes, the flashlight will generate a lot of heat. When the flashlight body internal temperature reaches 50 degrees Celsius, the brightness will decrease to 900lumens. This is to ensure safe, comfortable use and prevent discomfort from overheating. When the temperature is higher than 65 degrees Celsius, the turbo mode cannot be activated.
Firmware / UI Conclusion:
As mentioned in other reviews, cycling through modes from Low to High is nice, but you can't go backward. It would be far more efficient to have the option to cycle backward as well. For instance by using a single click to increase brightness and a press-and-hold to decrease brightness!
Batteries and charging:
Charging the Imalent LD70 is very easy because you don't have to take out the battery. Just connect the included magnetic USB charging cable to an external USB power source (the USB power source is not included).
The light can be charged through any USB power supply, including powerbanks or USB ports on desktops and laptops. Simply connect the magnetic cable to the magnetic interface of the flashlight.
You cannot go wrong with this connection since it will only fit one way and is very clear how to use it.
The OLED display will give an indication of the charging status by means of a blinking battery symbol. The battery symbol consists of 5 bars when the battery has reached 4.2 V. It then stops automatically after 5 seconds.
Charging the internal 18350, 1100 mAh battery, will take about 1 hour and 30 minutes.
Lux readings are done with a UNI-T UT 383 S lux meter, temperature readings are recorded with an infrared Non contact thermometer, type Benetech GM-320. Current readings are done with a UNI-T 210E Digital Clamp Meter
Unfortunately enough, the design of the Imalent LD70 does not allow any current measurements because it uses a built-in, nonreplaceable battery. Also, the light cannot be opened without using force and breaking it.
The charts show 2 different tests, both done after a full charge cycle. One test is done on Turbo and the other on Medium.
According to the manual, Turbo mode emits 4000Lm and should last for 1 minute, before it steps down to 900Lm that will last for another 38 minutes.
Well, Turbo output is measured at 3626 Lm, so it does not reach the claimed output of 4000Lm. Also, it doesn't last 1 minute, but it steps down at 30 seconds to ~2250 Lm. After 2.5 minutes, it steps down to ~700 Lm. And after 8 minutes it produces 500 Lm for another 30 minutes.
Medium mode is supposed to be 900 Lm for 45 minutes. That is not correct either, while it starts at 900Lm, it steps down to approx 630Lm after four minutes. After 13 minutes it steps down again to 500 Lm until the battery is almost empty within 42 minutes.
So the runtimes are quite accurate, but the numbers have to be taken with a grain of salt.
The results should be taken with a grain of salt since I am using an integrating Lumen tube which is not officially calibrated, so take into account a deviation of +- 10%
- Low: 53 Lm
- Medium: 173 Lm
- Medium 888 Lm
- High: 2044 Lm
- Turbo: 3626 Lm
- 1. 4 Lux @ m5 (approx 100 Cd)
- 2. 13 Lux @ 5m (approx 325 Cd)
- 3. 68 Lux @ 5m (approx 1700 Cd)
- 4. 161 Lux @ 5m (approx 4025 Cd)
- 5. 291 Lux @ 5m (approx 7275 Cd)
