P27iX - 5000 lumens

5,000 lumens, 430m throw, and a duty light you actually configure yourself. Twenty M515S LED cores in a 4×5 array. Switchable beam patterns. Two grip modes. Three programmable buttons. 5,000-lumen LUMIN SHIELD® broad-beam burst 2,500-lumen SEARCH mode reaching 430 meters Three beam patterns: long-throw, floodlight (~115°), mixed Two grip modes: Tactical and Duty Three customisable buttons with dual-stage configurations 5,500mAh NL2155HPi 21700 battery, 18W USB-C fast charging IP68 rated, 2m submersible, 2m impact resistant 7075-T6 aluminium alloy, HA III hard-anodised finish Silicon nitride ceramic strike bezel Patented Rapid Lock™ slide lockout ANSI/PLATO FL 1-2019 tested 143mm length, 124g (battery and accessory excluded) Built for SPF, SAF, auxiliary police, and licensed security operators. The first duty light in the precision series with a programmable user interface. CONFIGURE IT TO YOUR SOP, NOT THE OTHER WAY ROUND Two dual-stage tail buttons plus a side SET button. Both press stages on each tail button are independently programmable. Set Tactical Grip for response and entry. Set Duty Grip for shift work and admin tasks. Switch between profiles in seconds. The flashlight matches your unit's procedure instead of forcing you to learn around it. POWER YOU CAN COUNT ON THROUGH A FULL SHIFT The included high-discharge NL2155HPi 21700 cell delivers 5.5Ah at 20A continuous. That's what the M515S LED needs to sustain Turbo and full-burst output without sagging. 100 hours of runtime at the 15-lumen Low setting handles overnight posts and extended operations. Battery is user-replaceable. BUILT TO TAKE HITS CNC-machined from 7075-T6 aluminium alloy, the same series used in aerospace structural work. HA III hard-anodised finish stands up to scratching. IP68 dust and water rating, 2-meter submersion handling, 2-meter impact resistance. Six high-wear parts reinforced with stainless steel. The integrated ATR (Advanced Temperature Regulation) module monitors heat during sustained Turbo and full-burst output, easing back power gradually instead of cutting out abruptly. COMPACT WHERE IT MATTERS 143mm long, 32mm head diameter, 124g without battery. Fits a standard duty belt holster and sits comfortably in a uniform pocket. Status indicators on the side can be turned off when light signature matters. WHY THE P27iX EARNS A SPOT IN YOUR DUTY KIT Pure White Light Across Every Level Duv below 0.005 means the beam stays neutral and true at every output, from 15-lumen Low to full burst. No green tint at lower outputs, no yellow shift at peak power. Subject identification stays accurate under any brightness. 2nd Generation STROBE READY!™ Most strobe modes flash at a fixed frequency, which the eye learns to filter within seconds. The P27iX strobe randomly varies between 16Hz and 20Hz, so the disorientation effect stays effective for longer. Tested To International Duty Standards Output, runtime, throw, and intensity all tested per ANSI/PLATO FL 1-2019 — the international flashlight testing standard. Spec sheet numbers are field numbers, tested at 26°C using the included i-series battery. Stealth-Mode Indicators The four-LED output and four-LED battery indicators on the side can both be disabled. When light signature matters, the flashlight goes dark on its own status lights without losing functionality. Three beam patterns. Match the beam to the operation. LONG-THROW LIGHT At 1,500-lumen Turbo, projects to 302 meters. The central high-density LED core does the work, pushing a focused beam for perimeter overwatch, vehicle interception at distance, and target identification beyond standard duty light range. FLOODLIGHT Roughly a 115° illumination angle. The four peripheral flood cores spread light evenly across your immediate surroundings. Indoor sweeps, stairwell clearance, vehicle interior checks. MIXED LIGHT Both core types active at once. 1,500-lumen Turbo reaches 251 meters with a wide ~115° spread. Scan a large area and still pick out detail at range. The default beam for foot patrol and general response work. Switch between patterns through the side SET button. The flashlight remembers your last-used pattern. Anti-grab design. Always in hand, always in control. The angled rear control surface keeps your thumb on both tail buttons at once. Switch between momentary illumination and sustained output without re-gripping or moving your thumb. A conventional flashlight forces you to break grip every time you change function. That leaves the palm exposed and the body vulnerable to being knocked or grabbed during high-intensity contact. The P27iX keeps the flashlight locked in your hand through every press transition. The curved profile and stainless-steel button inserts hold up to gloved use, vehicle door slams, and quick draws from a duty holster. Four customisable settings. Map the controls to your habits. Both press stages on the Tail Button and the Engage Button are independently configurable. That's four distinct presses on the rear of the flashlight, each one assignable to a brightness level or special mode. TAIL BUTTON Half-press: Low or Mid (your choice). Full-press: High or Turbo (your choice). Use it like a two-stage trigger for brightness selection. ENGAGE BUTTON Half-press and full-press each independently configurable for instant access to LUMIN SHIELD®, STROBE, or SEARCH. No menu cycling. Set the configuration once. The flashlight behaves the same way every time you reach for it. M515S LED. Twenty cores in an X-shaped array. Self-developed by NiteLab. Four 5-core groups packed into one diagonally symmetric package. The central core handles long-throw with high luminous density. The four peripheral cores handle flood with high efficiency. Power gets allocated across the cores based on which beam pattern you select. Cores are spaced just 0.6mm apart, compared to 0.9mm in the previous-generation UHi 20 MAX. Tighter spacing means a more uniform hotspot and smoother beam transitions. A micro-textured orange-peel reflector around the LEDs softens the edge between hotspot and spill, so the beam transitions cleanly without harsh rings. Pure white light at every level. Duv below 0.005. Most flashlight LEDs shift colour temperature as output changes. Run them at low brightness and you get a green tint. Run them at full power and they shift yellow. The M515S holds Duv below 0.005 across every brightness level — the standard for "pure white" tint that closely matches natural daylight. For duty use that matters when subject identification, evidence assessment, or vehicle interior checks depend on accurate colour rendering. What you see is what's actually there, regardless of brightness setting. 5,000-lumen LUMIN SHIELD®. Maximum coverage on demand. One press, every LED core fires at full power. The result is a 5,000-lumen wide-spread burst that reaches 300 meters at 22,500 candela. Built for outdoor situations where you need maximum coverage immediately: vehicle stops at distance, large outdoor areas during a foot pursuit, perimeter sweeps after an alarm activation. LUMIN SHIELD® lives on the engage button by default in Tactical Grip mode. Re-map it to whichever press configuration matches your unit's procedure. 2,500-lumen SEARCH mode. 430 meters of focused reach. SEARCH mode dedicates power to the central long-throw core. Tight, concentrated beam that reaches 430 meters at 46,320 candela of peak intensity. That's beyond the effective range of most service-issued duty lights, on a flashlight that fits a standard belt holster. For perimeter overwatch, vehicle interception, treeline scanning during patrol, and target identification at distance. Activates from the engage button in Tactical Grip mode and is fully re-mappable. Random STROBE. One-handed activation. The strobe varies its flash rate randomly between 16Hz and 20Hz. Random timing matters operationally: a fixed-frequency strobe lets the eye adapt within a few seconds, but a varying one keeps the disorientation effect working through the contact window. One-handed activation through the engage button means you can deploy the strobe without breaking your grip or repositioning your thumb. Buys you time and distance before contact. Patented Rapid Lock™ slide lockout. A physical slide switch on the body disables every button. Slide it to the lock position and the flashlight cannot be turned on, even if buttons get pressed inside an assault pack, plate carrier pouch, or duty bag. Slide it back to unlock and you're live in under a second. No multi-click sequences, no accidental activation eating your battery before you need the light. Patented in the US, EU, and China — a Nitecore-exclusive solution rather than a borrowed one. Six high-wear parts in stainless steel. The parts that take the most contact in daily use — Tail Button, Engage Button, SET Button, Strike Bezel, Lockout Switch, and USB-C Port Cover — are reinforced with stainless steel rather than plastic or coated aluminium. These are the components that wear out first on a conventional duty light. Buttons get pushed thousands of times per shift. Strike bezels make contact with hard surfaces. Port covers flex open and shut every charge cycle. Stainless steel handles those load cycles for the life of the flashlight body itself. 5,500mAh of dedicated power. 18W of USB-C charging. The included NL2155HPi 21700 cell delivers 5.5Ah at 3.6V (19.8Wh) with a 20A continuous discharge rating. That's the high-current battery the M515S LED needs for sustained Turbo and full-burst operation. 100 hours at the 15-lumen Low setting handles overnight posts. The battery is user-replaceable for shift handovers and extended operations. FAST CHARGING 18W USB-C input through a PD or QC adapter brings the flashlight from empty to full in around 2 hours. Around 3 hours through a standard 5V/2A source. CR123 BACKUP The included magazine accepts 2× CR123 or RCR123 cells for environments where USB charging isn't reliable. Output is capped at 1,000 lumens to protect non-rechargeable cells from over-discharge. FOR EVERY OPERATIONAL ROLE Tactical Grip Mode For response and entry. Half-press for Low/Mid, full-press for High/Turbo, engage button straight to LUMIN SHIELD®, STROBE, or SEARCH. Duty Grip Mode For shift work and admin tasks. Cycles through four standard brightness levels plus warning flash. Easy on the thumb during long shifts. Field Operations CR123 backup for environments without reliable USB charging. 100 hours at Low for extended deployments. IP68 sealing handles tropical weather. Compact Carry 143mm and 124g without battery. Fits standard duty belt holsters and uniform pockets. Indicators disable for low-visibility posts.

CR123 backup is intended for emergency use when 21700 cells aren't available; maximum output is capped at 1,000 lumens to protect non-rechargeable cells, and the flashlight will not attempt to charge CR123 / RCR123 cells through the USB-C port. FREQUENTLY ASKED QUESTIONS Can I use the flashlight while it's charging? Yes — for standard brightness levels (Low, Mid, High, Turbo) and Warning Flash. LUMIN SHIELD®, SEARCH, and STROBE are disabled during charging because they exceed safe simultaneous-draw thresholds. Useful when you need to top up between shifts but want light available. How will I know when the battery is running low? Below 10% capacity, the battery indicator on the side flashes green and output may dim. The four-LED indicator system shows precise capacity in 25% increments (4 LEDs steady = 75-100%, down to 1 LED flashing = below 10%). At full capacity, all four LEDs stay solid green. Does the flashlight remember my last brightness and beam pattern? Yes, in Professional Mode. The flashlight stores your last-used brightness level and beam pattern, and reactivates with the same settings next time you turn it on. Each brightness level can also memorise its own beam pattern (Turbo with Long-throw, Mid with Floodlight, etc.) so you don't have to switch every time. Why does the flashlight dim during sustained Turbo use? The integrated ATR (Advanced Temperature Regulation) module monitors internal temperature during sustained high-output use and reduces output gradually to prevent overheating. This protects the LED and electronics from damage during extended Turbo or LUMIN SHIELD® bursts. Output recovers automatically once the body cools, and you can re-trigger LUMIN SHIELD®, SEARCH, or STROBE at any time to override.
