The New Weltool W3 Pro LEP Laser Flashlight;

So; the New Weltool W3 Pro LEP Laser Flashlight is an amazing piece of EDC technology! Weltool produced this fantastic LEP Laser in 2020 and called it the W3 Pro ‘Featherless Arrow’, and it is truly amazing.  Weltool sent me the W3 Pro (1.2km throw) and the W4 (2.6km throw) and I tested them accordingly. I also went out with the Acebeam W30 to compare, and the Weltool models certainly lived up to expectations and really performed well!  They were both fantastic to use, causing a lot of ‘wow’s’ coming from people out for a walk on the dark seafront pathways on the east coast of the UK!

The W3 Pro has a luminous flux of up to 505 lumens! The light intensity reaches 363375 Candela; the throwing distance is about 1205 metres! You can use one 21700 rechargeable lithium-ion battery (supplied); using high-quality constant current IC; and temperature control to ensure that the flashlight will not be too hot. The W3 Pro’s LEP light source has high energy density; and then passes through a special lens reflection system to form a dazzling light column! High and low modes are simple and practical. Please see diagram:

What is LEP?

LEP = Laser Excited Phosphor.
The Weltool LEP starts by focusing blue laser beams on a layer of fluorescence; initially emitting yellow fluorescence. This; combined with the remaining blue laser; creates the target white laser beam. The Weltool W3; “The Featherless Arrow”; leverages this technology as its core to create the white laser illumination. Since yellow fluorescence is a wide spectrum light, the white laser created from it is also a wide spectrum light. This is the technology at the core of not just Weltool Laser; but all laser illumination technology; bringing lamp life in excess of 10,000 hours.


The research team behind this remarkable light technology hails from the world famous Tsinghua University. This breakthrough work; fully resolved the Fluorescence Thermal Quenching issues; enabling the Fluorescence to fully withstand the high frequency laser activation and continuously emit bright light. Currently there are over 120 total technology patents, over 70 innovation patents, 1 international PCT, and 10 licensed patents.

The Weltool W3 Pro LEP Laser Flashlight uses an extremely focused laser beam to activate its Fluorescence; thus; all the light created from the activation will be focused to one tiny originating spot as an extremely tight focused beam, further transformed into a blinding pillar of light by a special reflector and lens system.
