DiscontinuedWeltool no longer makes this light; what dealers have left is the last of it. Its current replacement is Weltool W3Pro TAC.

Weltool's W3 Pro used a laser-excited phosphor (LEP) module rather than an LED, sending a 363,000-candela pencil beam over 1,200 meters from a head barely wider than the tube. Output was only 505 lumens, concentrated in a narrow spot, with a forward-clicky tail offering momentary, a two-mode UI and an included USB-C 21700 cell. The W3Pro TAC is its replacement.

Beam profile

Pencil thrower, about 2.4° wide. A tight, far-reaching column with almost no spill.

What owners report

Weltool W3 Pro/4 sources reviewed

An LEP light rather than an LED one — a laser-excited phosphor source, which is what allows 363,000 candela and 1,206 metres of throw from only 505 lumens. That ratio is the whole point: almost all of the output goes into a very tight column. Independent testing measured 363,000 cd against a claimed 363,375, which is about as close to spec as any light on this site gets.

Build quality draws real praise: the matte anodising gives it a higher-class look, the knurling is good, and there's reverse-polarity and thermal protection. It runs a 21700 and ships with a 5,000mAh high-amp cell. The one recurring irritation is mechanical: because the head-side o-ring has almost no lubrication and bare aluminium threads, trying to unscrew the tailcap often unscrews the head instead.

Consistently praised

1,206 m of throw and 363,000 candela — the longest reach on this site
Measured performance essentially identical to the published spec
Beautiful matte anodising and good knurling
Reverse-polarity and thermal protection built in
Ships with a high-amp 5,000mAh 21700

Common complaints

Unscrewing the tailcap often unscrews the head instead
Only 505 lumens — useless as a general-purpose light
LEP beams are extremely tight, with almost no spill
Low CRI, inherent to the technology
Expensive for the lumen figure if you don't specifically want reach

Questions people ask

What is an LEP light?: Laser-excited phosphor: a blue laser is fired at a phosphor target, producing white light from a tiny emitting area. Because the source is so small, a reflector can collimate it far more tightly than any LED — which is how 505 lumens reaches 1,200 m.
Is 505 lumens enough?: Not for general use. An LEP puts almost everything into a narrow column, so there's very little spill to light your surroundings. This is a spotting tool, not a torch.
Why does the head unscrew instead of the tailcap?: The head-side threads are bare aluminium with almost no lubrication on the o-ring, so they offer less resistance than the tail. A little silicone grease on the head threads fixes it.
How accurate are the specs?: Unusually accurate — testing measured 363,000 candela against a claimed 363,375. Weltool publishes figures that hold up, which is worth noting in this category.
