Nebo Slyde King 4K: seven lighting modes across three separate light sources
The Slyde King 4K uses the same patented slide to reveal design as the smaller model, with considerably more behind it. There are three distinct light sources here, a 4000 lumen flashlight, a 1000 lumen COB work light and a 40 lumen COB red task light, and between them they produce seven modes. Understanding what each is actually for is the difference between owning a capable light and using one.
The Slyde King 4K flashlight
High gives 4000 lumens reaching 350 metres for an hour. Low drops to 400 lumens and 100 metres and runs for six. The 4x adjustable zoom moves between a flood for close work and a tight spot for distance, so the flashlight alone covers a broad range of tasks before the work light is even revealed.
An hour at full output sounds short until you consider that 4000 lumens is not a setting anybody uses continuously. It is for identifying something, then dropping back down.
The work light and its 24 hour low
Slide the barrel and a COB panel appears along the side. High gives 1000 lumens over 35 metres for 4 hours. Low gives 100 lumens for 24 hours.
That 24 hour figure is the specification worth noticing on this torch. One hundred lumens of broad even panel light is enough to work under, read by, or light a tent or a vehicle interior, and a full day of it from one charge turns this from a torch into something you can rely on through an extended outage or a night shift without rationing.
Zoom, and what it is doing at this output
The 4x adjustable zoom matters more here than on a lower output torch. Four thousand lumens spread wide is an enormous amount of near field light, enough to turn a yard or a work area into something approaching daylight. The same output narrowed down is what carries 350 metres. Most torches make you choose one behaviour when you buy; this one lets you choose it per task with a twist of the head.
Between the zoom range and the three separate emitters, this covers about as wide a spread of lighting jobs as a single handheld unit reasonably can, which is the argument for the slide design in the first place.
The red task light
The red COB runs 40 lumens for 6 hours on high, 4 lumens for 35 hours on low, and 40 lumens flashing for 12 hours. Direct-to-Red Startup means the red comes on first, without the white output firing in between and undoing your dark adaptation. The flashing mode marks a hazard, a vehicle or a position for hours without touching the main battery in any meaningful way.
Getting back to your setting
Power Memory Recall returns the light to whatever mode it was on when you switched it off. On a light with seven modes that matters more than it would on a two mode torch, because the alternative is cycling through everything to find the one you had. Output is dimmable throughout rather than fixed at the published steps, so the figures above are points on a range rather than the only options.
Where it belongs
Nebo pitches this at professional work, DIY, camping, emergencies and everyday use, which is a broad claim that the hardware happens to support. A vehicle boot is probably its natural home. It is too heavy at 500 grams for pocket carry and too capable to leave in a drawer, and the combination of a long throw beam, a panel light and a magnetic base is close to exactly what a roadside breakdown, a load shedding evening or a job in an unlit building calls for.
Power
A 2600 mAh 20650 lithium ion cell at 3.7 V drives everything, charged over USB-C, with a built in charging indicator. One cell running three light sources is part of why the low settings stretch as far as they do: the COB panels are far more efficient per lumen than the focused emitter.
Where the seven modes come from
Counting them out: flashlight high and low, work light high and low, red steady high and low, and red flashing. Seven modes on a torch usually signals a specification sheet padded with variations nobody uses. Here they map onto three physically separate light sources with genuinely different jobs, which is a different thing from one emitter offered at seven brightness levels.
The practical consequence is that this replaces a torch, a work light and a marker light rather than approximating all three badly with one beam.
Build and handling
Anodised aircraft grade aluminium, impact resistant, with IPX7 waterproof protection. A magnetic base holds it to steel for hands free operation, which is where the work light earns its place, stuck to a vehicle wing or a machine housing while both your hands are occupied. It weighs 500 grams and measures 207 millimetres closed, extending to 260, at 45 millimetres in diameter.
