The Ledlenser P18R Signature is a large, high-output rechargeable torch, and it is no longer in production. Ledlenser's own product page says so plainly: "THIS ITEM IS NO LONGER IN PRODUCTION. This page is for information only."1 That matters before anything else. You cannot buy one new from the maker, so this page is for people who already own one, were given one, or are considering a secondhand example and want to know what it can do and how to look after it.
What it is, in practical terms, is a searchlight-sized handheld torch with a focusable beam, a rechargeable battery pack and a set of modes built for signalling as well as lighting. Ledlenser calls it a "premium, high-performance flashlight"2 and describes the P18R family as a "high-performance searchlight" that "delivers a bright, wide-reaching beam"3. For a household, that means it is not the torch you keep by the bed for a power cut. It is the one you take outside to check a fence in a storm, light a driveway, or signal for help from a distance.
The headline figures are large and the maker's pages do not all agree on them. One page gives 4500 lumens1; another gives a 7000 lumen Boost Mode2. Run time on the lowest setting is quoted as up to 45 hours2. A full charge from flat is given as 3.5 hours on one page2 and 330 minutes on another1. Where the maker's own pages conflict, this page gives both figures and says so, rather than picking one.
A discontinued model: what that means if you are buying
Because the P18R Signature is out of production, every example now in circulation is either already owned or secondhand. Ledlenser's page exists to give information on a product it no longer sells1. That changes what you should check before parting with money for one.
The parts that wear or go missing are the ones to confirm are present. Ledlenser lists the box contents as the torch, three 18650 rechargeable lithium-ion battery packs, an adjustable wrist strap, a Wall Mount Charging Station Type E, a USB-C to USB-C charging cable and a hard storage case2. A secondhand torch sold without its battery pack or charging station is harder to use, because the pack is a specific 18650 lithium-ion unit at 11.1V2, not a standard household battery.
Ask the seller for the original receipt and any registration details. The warranty is a standard two years, extendable by a further five with online registration, up to seven years, covering manufacturing defects1. Whether that transfers to a second owner is not something the maker's pages state, so treat a secondhand warranty as uncertain until the seller can show the paperwork.
If you want a torch you can buy new today, the wider guide to torches for the home sets out the types and what each suits. If you specifically want another Ledlenser, the Ledlenser brand page lists the models currently offered.
What the P18R Signature is and what it suits
This is a torch built around reach rather than room-filling light. Ledlenser describes it as a rechargeable torch and a premium, high-performance flashlight2, and the P18R family as a high-performance searchlight3. The beam distances back that up: 440 metres on Standard Power and 240 metres on Mid Power on one maker page2, and 630 metres in Boost Mode on another2.
For an ordinary household, that reach is useful in specific situations rather than everyday ones. Checking the far end of a garden, a driveway, an allotment or a field after dark; finding a stopcock or a boundary fence in bad weather; signalling across distance. It is heavy for its size at 651g2, which is fine held in two hands or rested on a wall, less comfortable for a long walk or for a child to carry.
The light itself is cool white2 with a colour rendering index of 702, and the maker quotes a colour temperature of 6000k to 7500k on one page2 and 6000k to 7200k on another1. Cool white light shows detail and distance well; it is less restful than a warm white lamp for lighting a room for hours.
The torch uses three LEDs2 and Ledlenser's X-Lens Technology, which the maker says "merges multiple reflector lenses and synchronises their individual light beams into a single perfect beam"1. In use, that is what gives it both the reach and a usable spread when you focus out to flood.
Specifications: size, weight, battery and build
The torch is substantial. Ledlenser gives a length of 196mm2, a head diameter of 86mm2 and a tube diameter of 47mm2. The maker's other page gives a focused length of 178mm and a defocused length of 171mm1, which does not match the 196mm figure; the pages disagree, so treat the length as roughly 170 to 200mm depending on focus. Weight is given as 651g2.
| Specification | Figure | Source |
|---|---|---|
| Type | Rechargeable torch, high-performance searchlight | 2 |
| LEDs | 3, cool white | 2 |
| Length | 196mm (maker's other page gives 178mm focused, 171mm defocused) | 2 |
| Head diameter | 86mm | 2 |
| Tube diameter | 47mm | 2 |
| Weight | 651g | 2 |
| Battery | 18650 lithium-ion pack, 3200 mAh, 11.1V | 2 |
| Housing | 75% recycled aluminium, hard anodised finish | 2 |
| Drop test | 1 metre | 2 |
| Working temperature | -20C to +40C | 2 |

The battery figures also conflict between the maker's pages. One gives 3200 mAh2; the P18R (a related but different model) is listed at 2100 mAh with a three-cell 18650 pack3. The Signature page's 3200 mAh is the figure to use for the Signature, but note that the maker's material is not consistent across the range.
The build is aimed at outdoor use. The housing is 75% recycled aluminium2 with a hard anodised finish that Ledlenser says "protects against wear and corrosion"1, and the torch is drop tested to 1 metre2. That is a sensible standard for a torch carried outdoors, not a claim that it survives being driven over.
Run time: up to 45 hours on low power
The run time depends entirely on which mode you use, and the difference is enormous. On Low Power the maker quotes 100 lumens, 45 metres and 45 hours2, and describes it as "up to 45 hours of runtime"2. At the other end, Standard Power is quoted at 3500 lumens, 440 metres and 2 hours2, and Boost Mode at 7000 lumens for 630 metres2.
| Mode | Brightness | Beam distance | Run time |
|---|---|---|---|
| Low Power | 100 lumens | 45 metres | 45 hours2 |
| Mid Power | 1000 lumens | 240 metres | 5.5 hours2 |
| Standard Power | 3500 lumens | 440 metres | 2 hours2 |
| Boost Mode | 7000 lumens | 630 metres | short burst2 |
The maker's pages disagree on some of these. One page gives Low Power as 30 lumens, 50 metres for 70 hours1, and Standard Power as 2600 lumens, 420 metres for 2.5 hours1, and Mid Power as 1000 lumens, 260 metres for 4.5 hours1. The other gives the figures in the table above2. Both are the maker's own pages, and neither has been ruled correct, so treat the run times as approximate and expect the lower-brightness settings to last longest.
The practical lesson for a household is the same either way: the torch will run for a very long time if you keep it on its lowest setting, and for a couple of hours at most if you use it at full power. For a power cut, that means using it as a searchlight only when you need to see something far away, and dropping to Low Power for anything close. The guide to lumens, beam distance and run time explains why the two trade off against each other.
Light modes for an emergency: SOS, position and blink

The P18R Signature carries a full set of modes: Low Power, Mid Power, Standard Power, Boost Mode, Blink, Position, S.O.S and Strobe2. For an emergency, three of these matter.
S.O.S emits the Morse code distress signal: three short, three long, three short2. Position gives two short pulses of light, repeated three times, "to alert others of your location"2. Blink is the "automatic emission of light impulses at regular intervals"1. These are the modes to reach for if you need to be found, and they are designed to be recognisable to someone looking for you.
Strobe is different. Ledlenser describes it as "flashes of light with a confusing blinding effect"1. It is not a distress signal and it is not a substitute for SOS. It is also bright enough to be disorienting, so keep it away from people's eyes, including your own, and do not use it as a toy.
The torch also has a Memory Function, which "sets the light so that it starts in the last light mode or brightness level used when it is switched on"1. That is convenient day to day, but it means a torch left in Boost Mode will come back on in Boost Mode. Before a storm or a forecast power cut, set it to Low Power so that the first press gives you long run time rather than a two-hour burst.
The guide to SOS and strobe modes on a torch covers when each is appropriate and how to use them without wasting battery.
Charging: 3.5 hours from flat by USB-C or wall station
The torch charges two ways: through a USB-C charging port, which Ledlenser says "offers fast, efficient, and universally compatible charging"2, or through the Wall Mount Charging Station Type E supplied in the box2. A full recharge from flat is given as 3.5 hours on one maker page2 and 330 minutes on another1. The two figures disagree; 3.5 hours is 210 minutes, so the maker's own pages are not consistent. Plan for somewhere between three and a half and five and a half hours.
The battery is a specific 18650 lithium-ion pack at 11.1V2, not a set of household cells. Charge it with the supplied cable and station where possible, and follow the maker's instructions for the pack rather than substituting a charger. The guide to charging and storing rechargeable torches safely sets out the general precautions for lithium-ion packs at home.
The torch has a battery status and charge indicator and a low battery warning, which Ledlenser says means "you always know where you stand on power"1. It also has a Temperature Control System that "keeps light from overheating so it can run brighter and longer"1. Both are useful in a long outage: you can see how much charge is left before you commit to a bright mode.
Use and storage in a power cut: transport lock, backup mode and emergency light
Three features make this torch more useful in an outage than its size suggests.

The Transport Lock means it "will not turn on accidentally and use up battery"1. Store it locked, and it will still have charge when you need it. The Backup Mode monitors the charge level and, when it runs low, "drops to the low-power mode, giving you about 1 hour of remaining light"1. That is a warning as much as a feature: when the torch dims itself, you have roughly an hour of light left and should charge it or switch to a spare.
The Emergency Light feature is the one to know about. Ledlenser says that "if the power goes out while your Ledlenser is charging, it will automatically turn on to give you light"1. Left in its charging station, the torch becomes a power failure light. That is a genuinely useful behaviour in a cut, but it also means the torch will be on when the power fails, so check it is somewhere sensible rather than buried under coats.
For storage, keep the torch and its spare packs indoors at room temperature. The working range is -20C to +40C2, so a cold shed is within the maker's range, but a lithium-ion pack holds charge better and charges more safely at normal indoor temperatures. Store it locked, partly charged rather than flat, and check it before winter. The power cut checklist and the guide to lighting your home safely when the power goes off set out where a torch like this fits alongside lanterns and smaller lights.
Waterproofing, dust and cold weather

Ledlenser's pages disagree on the ingress rating. One states an IP68 rating, saying the flashlight "is fully protected against dust and water"2. The material also carries an IP54 figure. IP68 is the stronger claim, but because the maker's own pages conflict, do not treat the torch as dive-rated. It is sensible for rain, splashes and muddy ground; do not submerge it deliberately.
The working temperature range is -20C to +40C2, which covers a British winter comfortably. Cold still affects any lithium-ion pack, so keep the torch and spares indoors rather than in a cold car boot, and let it come back to room temperature before charging if it has been outside in freezing weather. The guide to what IPX ratings mean for torches and lanterns explains the rating system.
Warranty, UK support and returns
Ledlenser offers a standard warranty of two years, extendable by a further five years with online registration, up to seven years, covering manufacturing defects1. The maker's other pages repeat the same terms4, and one page simply lists "7yr Warranty with Registration"3. The two descriptions agree in substance: two years as standard, seven if you register.
Registration is worth doing. Ledlenser says to "Register your light for extended peace of mind and long-term reliability"4. The maker also advertises "Fast Delivery & Free UK Returns"4 and "Friendly, knowledgeable support from our UK team whenever you need assistance"4, and describes its products as "Engineered in Germany"4.
For a discontinued model, the warranty is the main route to support if something fails. Keep the receipt and registration details, and contact the UK team through the maker's site. If you are buying secondhand, ask whether the torch was registered and whether the warranty can be transferred; the maker's pages do not say, so do not assume it can.
