NWH20 Dual-Beam Rechargeable Headlamp (600 Lumens)

Spotlight to floodlight at the push of a button Most work headlamps lock you into one beam. The NWH20 moves electronically between a focused spotlight and a wide floodlight while it stays on your head, so one lamp covers the panel in front of you and the yard beyond it. 600 lumens on tap, throwing 89 metres at 1,982 candela Electronic stepless spot-to-flood control, adjusted with the buttons and saved Four quad-core UHE LEDs at 4,500K neutral white, plus an auxiliary red light Removable WLB40 4,000mAh battery, recharged over USB-C in about four hours Tilts up to 160 degrees and clips onto a hard hat with the four clips in the box Built to a 2 metre drop rating and sealed to IP66 against dust and water 149 grams on your head with the battery fitted One light does the close work and the long look A patented electronic focus shifts the beam from a tight spot to a broad flood without swapping lamps or fitting a diffuser. Drop to a wide floodlight to fill a server room, a switch cabinet or the engine bay you are leaning over, then tighten to a spotlight to read a gauge across the yard or check a line at range. Because the change happens at the button, both hands stay on the job and you keep the workflow moving. Dial in the exact beam, and keep it Hold the ZOOM button and the spotlight and floodlight blend steplessly, so you set the precise spread a task needs. Release to confirm, and the lamp remembers that ratio. It applies to the other brightness levels and returns to it the next time you switch on, so you set your beam once rather than re-adjusting all shift. A short press of the same button jumps straight between Mixed, Floodlight and Spotlight when you want a quick change. 600 lumens, 89 metres of reach Full output puts 600 lumens and 1,982 candela down the site, reaching 89 metres. That covers a line inspection, a dark stairwell or the far side of a compound. Below it sit HIGH at 450 lumens for 7 hours, MID at 300 lumens for 12 hours and LOW at 150 lumens for 17 hours, which is where most of a shift is actually spent. TURBO steps down after a sustained run to keep heat in check and protect the battery. Runtime that clears a full shift At the 300 lumen MID setting the NWH20 runs for 12 hours, enough to cover a working day on a single charge. Ease back to the 40 lumen ULTRALOW and it holds for 51 hours for close work in a cabinet or a crawl space. A built-in temperature sensor watches the battery and adjusts output to keep things stable when a job runs long. Swap the battery or charge over USB-C The WLB40 4,000mAh pack lifts out, so a charged spare gets you straight back to work with no downtime waiting on a cable. When you do charge, the USB-C port sits on the battery itself and refills in about four hours from a standard 5V/1A adapter. Three blue indicators on the pack show the level at a glance, and step from flashing to steady as it fills. Want one always charged and ready? Add a spare WLB40 battery and keep the light running through the longest shifts. Neutral white for true colour, red when you need it The main light runs at 4,500K neutral white, close to daylight, so wiring colours, labels and finishes read the way they should and your eyes tire less over a long job. An auxiliary red light comes on separately at 20 or 5 lumens and holds night vision when you step out of a lit space, with a slow flash for marking your position. Long press the ZOOM button from off to reach it without cycling through the white. A clean, even beam from the UHE matrix Four quad-core UHE LEDs, sixteen cores in total, sit behind a multi-faceted TrueVision+ lens rather than a plain reflector. The lens passes 94% of the light the LEDs produce, so very little is lost on the way out and the beam lands as a smooth, usable field rather than a harsh hotspot ringed by dark. For work up close that means you see the whole task evenly, with no tunnel of bright in the middle and shadow at the edges. 160 degrees of tilt The head pivots through 160 degrees, so the beam points at your hands on a bench, straight ahead down a corridor or up at an overhead fitting. The detent holds the angle you set and stays put through a shift rather than creeping down as you move. Fits your hard hat, comfortable bare-headed The four hard hat clips in the box lock the lamp onto a helmet, and the wide 32mm anti-slip headband holds it steady when you would rather wear it on its own. Reflective marking on the band adds visibility on site at night. At 149 grams with the battery in, there is little weight to notice over a full day, whether it is on a helmet or on your head. Built for the site, not the shelf IP66 DUST AND WATER RESISTANCE - Sealed against dust ingress and heavy jets of water, so rain, spray and a dusty worksite are all well inside what it handles. 2 METRE DROP RATING - The reinforced composite body and bracket take a fall from working height and keep running, with an all-weather elastic layer over the housing. ATR THERMAL REGULATION - The Advanced Temperature Regulation module trims output to hold safe temperatures on long high-power runs, so performance stays stable rather than cutting out. TWO WIDE BUTTONS, USED IN GLOVES Turn it on and set brightness Short or long press the Power button to switch on, then short press to step LOW, MID, HIGH. Long press to switch off. Change the beam Hold ZOOM to blend spot and flood steplessly, or short press it to jump between Mixed, Floodlight and Spotlight. Reach TURBO or ULTRALOW Double press Power while on for the 600 lumen TURBO. Double press Power from off to start at the 40 lumen ULTRALOW. Switch to red From off, long press ZOOM for the red light, then short press Power to move between red LOW and red HIGH. Signal for help Double press ZOOM at any time for SOS, then Power moves to Beacon and Slow Flashing. Lock it for the toolbag Hold both buttons together to lock the lamp so it cannot switch on in transit and drain the battery. Hold both again to unlock. The two buttons are different in shape and feel, so you can tell them apart by touch in the dark or through work gloves. HOW THE NWH20 COMPARES Electronic focus, not a fixed beam Most work headlamps ship one beam and a clip-on diffuser you lose. The NWH20 changes spot to flood at the button and remembers your setting. Swappable battery, not a sealed cell The WLB40 lifts out for a fresh pack in seconds, where a sealed lamp leaves you tethered to a charger. Rated for the conditions IP66 sealing and a 2 metre drop rating are built for dust, rain and a fall from height, not fair-weather use. Made to mount Four hard hat clips and a wide anti-slip band come in the box, so it goes on a helmet or your head from day one. WHO IT IS FOR Electricians & utility Flood a switch cabinet, then spot a line at range. Neutral 4,500K white reads wiring colours true, and both hands stay free. Construction & hard-hat trades Four helmet clips, 160 degrees of tilt, IP66 sealing and a 2 metre drop rating for daily site use. Maintenance & servicing 12 hours at 300 lumens covers a shift, and a spare WLB40 gets you straight back to work when it runs low. Emergency & night response SOS, Beacon and a red slow flash for signalling, red light to hold night vision, and wide buttons that work in gloves.

Yes. The WLB40 4,000mAh pack unscrews and lifts out, so a charged spare gets you back to work with no wait. The battery charges over USB-C on the pack itself, so you can top up one while a second is in the lamp. Does the brightness drop on the highest setting? TURBO steps down after a sustained run. The ATR thermal module trims output to hold a safe temperature and protect the battery on long high-power runs, then lets it climb again as things cool. HIGH at 450 lumens holds steady for 7 hours if you want constant output. It will not switch on after I changed the battery. What now? Check whether it is locked, since the lockout stays set through a battery change. Hold both buttons together until the light comes on and it is unlocked. Locking it before the lamp goes in a toolbag is what stops it turning on in transit and draining.
