Introduction#
The IMALENT LD35 Premium Edition is an 18350-sized EDC torch with a micro-arc oxidation finish, a Luminus SFT25R emitter and an OLED display. It comes with a LD00 Charging Case that can charge the LD35 or be used as a USB-C powerbank.
IMALENT are known for their powerful flashlights.
I previously reviewed the IMALENT MS12 Mini (it is extremely powerful a massive compared to the LD35).
Neal kindly provided this torch for review. I have not been paid for this review nor have I held back my opinions of this torch.
Packaging#
The IMALENT LD35 comes in a small black box with shiny blue metalic lettering.
The following was included in the box:
- IMALENT LD35.
- LD00 Charging Case.
- USB-C PD Charging Cable.
- Lanyard.
- User manual.
Torch in use#
The IMALENT LD35 comes in a LD00 Charging Case.
The case has a removable magnetic fabric top.
It reminds me of an Amazon Kindle fabric cover.
Do you know what the pattern on the side of the LD00 Charging Case means?
The IMALENT LD35 feels slightly short in my hand.
The metal tail switch feels good!
There is an OLED display to show the mode and the battery status.
The torch can tail stand and there are two holes in the tail if you want to attach a lanyard.
Build quality#
The IMALENT LD35 is made of aluminium and it has a micro-arc oxidation finish.
There is plenty of grip on the side of the torch.
The torch came with protective film on the lens that must be removed before using it.
I like how IMALENT have dimmed the OLED display so that it isn’t too bright.
The case has a premium feel.
Overall, the build quality is excellent.
LED, bezel, lens, reflector and beam#
The IMALENT LD35 has a Luminus SFT25R emitter.
There is a glass lens with an anti-reflective coating sitting behind two press-fit bezels.
Behind the glass lens is a 5 degree TIR optic. And behind that is a smooth aluminium reflector.
CCT, CRI, and duv#
I have taken Correlated Colour Temperature (CCT) and Colour Rendering Index (CRI, RA of R1-R8) measurements with the torch positioned one metre away from an Opple Light Master Pro III (G3).
The CCT is around 5700K, the CRI is around 63 and the Delta u, v is positive (green) on lower modes and less green on high modes.
The beam produced has an intense white hot spot surrounded by a narrow green corona. There is a narrow and smooth spill with an outer ring produced by the TIR optic and bezel.
| Mode | CCT (K) | CRI (Ra) | x | y | Duv |
|---|---|---|---|---|---|
| Low | 5601 | 61.9 | 0.3299 | 0.3643 | 0.0125 |
| Middle Low | 5663 | 62.7 | 0.3284 | 0.3609 | 0.0116 |
| Middle | 5758 | 63.5 | 0.3262 | 0.3563 | 0.0104 |
| High | 5897 | 64.6 | 0.3231 | 0.3502 | 0.0088 |
| Turbo | 6028 | 65.7 | 0.3206 | 0.3445 | 0.0072 |

| Off | Click | On (mode memory) |
| Off | Hold | Nothing |
| Off | Two clicks | Turbo |
| Off | Three clicks | Battery status |
| Off | Four clicks | Lock |
| On | Click | Off |
| On | Hold | Cycle (Low, Middle Low, Middle, High) |
| On | Two clicks | Turbo |
| On | Three clicks | Battery status |
| Turbo | Two clicks | Strobe |
| Strobe | Two clicks | Turbo |
| Locked | Four clicks | Unlock |
Mode Memory#
Turbo and Strobe are not memorised.
Strobe#
Strobe has a constant frequency.
I measured Strobe with a Zoyi ZT-703S oscilloscope using High Speed mode.
Battery status indicator#
The battery voltage will be displayed for 5 seconds after pressing the button 3 times from off.
The OLED display will switch between displaying the mode and then the voltage every second when the torch is on.
Pulse Width Modulation#
I did not notice any visible PWM (flickering).
I measured the PWM of the light with a Zoyi ZT-703S oscilloscope.
Low, Middle Low, Middle, High, Turbo
What I like about the UI#
- I like how the OLED display is slightly dim.
- There is a shortcut to Turbo from off and on.
- There is a lockout mode.
What could be improved#
- A sub-lumen Moonlight mode would be nice for this EDC torch.
- A shortcut to Moonlight from off would be nice.
- A shortcut to Strobe from off would be nice.
- The OLED display will switch between displaying the mode and then the voltage every second when the torch is on. This seems unnecessary and it can be a bit distracting.
Batteries and charging#
Battery#
The IMALMENT LD35 has a built-in 18350 Li-ion 1100mAh cell.
THe LD00 Charging Case came with an insulating strip that must be removed first so that the LD35 may charge inside the case.
Charging#
The LD00 Charging Case can charge the LD35 at a rate of 4.2V/1A.
The case can charge the LD35 about two times before it needs to be charged.
It takes about 1 hour to charge the case and 55 minutes to charge the LD35.
LD00 Charging Case Specifications:
USB-C Input: 5V/4.8A to 12V/2A.
USB-C Output: 5V/3A, 9V/2A, 12V/1.5A.
There is a green indicator near the USB-C port that flashes while the LD00 is charging. It becomes a solid green when the case is full.
I charged the LD35 from 3.12V to 4.12V inside the LD00 Charging Case.
Powerbank#
The LD00 Charging Case has a built-in 3800mAh battery and USB-C fast charging.
The USB-C port can be used to charge a device such as a phone.
These are the protocols that were detected by various USB Meters:
QC3+ 5V, 9V, 12V, 3.6-12V
FCP 5V/2A, 9V/2A, 12V/1.5A

| PinePower Desktop | USB-A | Yes |
USB-C to USB-C charging works.
Performance#
Specifications from the user manual:
| ANSI/NEMA FL1 | Turbo | High | Middle | Middle Low | Low |
|---|---|---|---|---|---|
| Output (lumens) | 1,200 + 600 | 600 | 300 | 100 | 5 |
| Runtime | 80s + 44min | 50min | 2h 30min | 8h 30min | 42h |
| Beam Distance (metres) | 328 | ||||
| Beam Intensity (cd) | 26,910 |
Lumen measurements#
| Mode | Specs | Lumens @turn on | Lumens @30 sec | Lumens @10 min |
|---|---|---|---|---|
| Low | 5 | 14 | 12 | 12 |
| Middle Low | 100 | 75 | 75 | 75 |
| Middle | 300 | 230 | 230 | 228 |
| High | 600 | 563 | 556 | 534 |
| Turbo | 1,200 + 600 | 1,242 | 1,088 | 527 |
The lumen output that I measured was slightly lower compared to what IMALENT claim. My DIY lumen tube tends to read slightly lower when there is a TIR optic.
Runtime graphs#
I used my own DIY lumen tube with a TSL2591 sensor and forked bmengineer’s project RuTiTe to record runtimes.
Note: Lumen measurements may be off by 10% with my DIY lumen tube.
The room temperature was approximately 21 C.
Runtime#
Here is a summary of the runtime results:
| Mode | User manual | Runtime | Turn off | Final Voltage |
|---|---|---|---|---|
| Turbo | 80s + 44min | 46min 38s | 46min 38s | 3.12 |
| High | 50min | 51min 28s | 51min 28s | 3.07 |
| Middle | 2h 30min | 2h 34min 54s | 2h 34min 54s | 3.06 |
| Middle Low | 8h 30min | 8h 33min 17s | 8h 33min 17s | 3.02 |
| Low | 42h | 42h+ | 42h+ |
“Runtime” is the time until the output reduces to 10% of the output at 30 seconds (as per the ANSI/PLATO FL1 2019 Standard).
“Turn off” is the time until my DIY lumen tube no longer detects more than one lumen.
“+” indicates that the light remained on after recording had stopped.
The runtime results were slighly better than expected.
The output is well regulated.
Throw#
I took lux measurements with a UNI-T UT383BT at 30 seconds. Low was measured at one metre. Middle Low to Turbo were measured at five metres.
| Mode | Specs (cd) | Specs (m) | Candela measured (cd) | Distance (m) |
|---|---|---|---|---|
| Low | 427 | 41 | ||
| Middle Low | 2,575 | 101 | ||
| Middle | 8,350 | 182 | ||
| High | 21,575 | 293 | ||
| Turbo | 26,910 | 328 | 40,400 | 401 |
Beamshots#
I went to a local park and aimed the torch at a tree 70 metres away while using Turbo.
Beamshots were taken using a Sony RX100M2 using 3.2", f3.2, ISO 100, 5000K WB.

Conclusion#
The IMALENT LD35 may be a great addition to your EDC bag if you want a compact torch and powerbank to match your Kindle and Airpods.
The torch and case have a premium look and feel.
The OLED display makes it easy to see what mode the torch is currently in.
The fabric cover of the charging case matches the case for my Kindle perfectly.
This torch and powerbank combo has two built-in batteries. A 1100mAh battery in the torch and a 3800mAh battery in the charging case. It is something to consider for the long run. Then again, if you have a Kindle and Airpods then you’re probably used to sacrificing the ability to easily replace batteries in exchange for the compact features that they offer.
The build quality is excellent and the torch performed well in most areas.
The lumen output could be better but the beam distance was better than expected.
I would say that the CRI is a bit low for an EDC flashlight but I would imagine that you would buy this torch for the style and performance.
The amount of fast charging protocols that the charging case supports is impressive!
Do I recommend it? It is a very niche torch. If it looks like the perfect addition to your EDC bag, then I would highly recommend it!
