Descrizione
A flashlight is trusted for exactly one property, and it is not the lumen count printed on the box. Emitters are cheap and every specification sheet can quote a large number for half a second. What matters is whether the light still delivers its rated output after ten minutes of continuous use, when a driver without thermal control has already throttled itself down to something closer to a phone screen.
This unit pairs a single XHP50B emitter at 6000 to 6500K with a regulated driver and active temperature regulation, drawing on one 21700 lithium cell. The 21700 is the part that changes the character of the light: it is a substantially larger cell than the 18650 most torches this size use, which is where the sustained runtime comes from rather than the peak number. Output is selected across five to eight brightness levels with High, Middle and Low modes available from a dual switch, and a power indicator means you know the state of the cell before you leave the house rather than after the light dims.
Output is a claim. Sustained output is a specification.
The Specification That Actually Matters
- ✦ Single XHP50B emitter at 6000 to 6500K, driving up to 3800 lumens
- ✦ Active temperature regulation to hold output rather than spike and collapse
- ✦ 21700 lithium-ion cell included, with 3.0V to 4.2V operating voltage
- ✦ USB Type-C rechargeable, so the torch charges from the same cable as your phone
- ✦ Five to eight brightness levels with High, Middle and Low modes on a dual switch
- ✦ Reach of 200 to 500 metres from a compact 139.5 mm by 28 mm body
- ✦ Aerospace-grade 6061 aluminium, CNC machined and hard-anodised to military type III specification
- ✦ Shock-resistant, anti-crash geometry, 87 grams without the cell, waterproof body

Where A Light Like This Earns Its Keep
The first place is the car. A torch that lives in a glovebox is only useful if it is charged when you need it, and USB Type-C charging plus a power indicator is what makes that realistic. Changing a wheel on a dark shoulder, finding a dropped key under a seat, walking to a gate that has no light: the 21700 cell means the light is still at usable output after a long spell of continuous use rather than fading in the first ten minutes.
The second is the building trade and site work. High, Middle and Low gives you a wide beam for walking a site and a tight, bright setting for inspecting a duct or a void. The 6061 aluminium body with a type III hard-anodised finish is the part that survives being dropped on concrete and thrown in a tool bag, and the temperature regulation is what stops a cheap light from becoming uncomfortable to hold on a long inspection.
The third is outdoor use where weight and reach both matter. At 87 grams without the cell and 139.5 mm long, it disappears into a jacket pocket, but the beam reach of up to 500 metres is more than most camping and trail torches manage. That combination is why a single-cell tactical light ends up being the one people actually carry rather than the one they leave at home.
Questions We Get Asked
Q: Does the battery come included?
Yes. A single 21700 lithium-ion cell is supplied with the torch, and the battery is rechargeable in the light over USB Type-C.
Q: Why does it use a 21700 rather than an 18650?
A 21700 is a physically larger cell with more capacity in the same class of light. That extra capacity is what allows the torch to hold a genuinely useful output over a long period instead of relying on a brief peak.
Q: Will it get too hot to hold?
Active temperature regulation manages the output as the body warms, which is why the sustained output is lower than the first-second peak. The driver is doing its job when the brightness steps down rather than letting the body become unpleasant.
Q: Is the beam adjustable?
No. The reflector is fixed, which is deliberate for a light used for both walking and inspection. There is no sliding focus mechanism to drift or leak.
Q: Which modes are available?
High, Middle and Low across five to eight brightness levels, selected with the dual switch. The power indicator shows the state of the cell so you can check before you go out.
Q: Is it waterproof?
Yes, the body is sealed for use in rain and wet conditions. Do not use it as a diving light, and check that the tail cap is fully seated before submerging it in anything.
Q: Can I use it for self defence?
It is specified for hard light and self-defence use, and the bezel geometry is built for that role. It is a light, not a weapon, so treat it as a way to disorient and create space rather than as a substitute for awareness.
Q: How heavy is it to carry daily?
87 grams without the battery, and 139.5 mm long, which puts it in the category of a light you can carry in a jacket pocket or on a belt without noticing it. With the 21700 cell fitted it still sits under most compact torches of comparable output.
