Weltool W3 Pro “Featherless Arrow” 1.2km thrower

The Weltool W3 got a worthy successor. 2 years after the first LEP flashlight entered the market, Weltool upgraded its popular LEP Flashlight. The new W3 PRO doubled the number of lumens and doubled the amount of beat intensity. That by itself is already exciting enough.

While the original W3 had a maximum output of 200 lumens and a beam intensity of 180,000 cd (candela), its successor can produce 505 lumens and 363,000 cd.

Fortunately enough, the W3 PRO still uses the double mode user configuration. You can extend battery life with the low mode, which is good for 102 lumens and 72,000 candela.

Both lights look pretty similar on the outside, but there are some noticeable differences. First off, the first generation W3 uses 18650 batteries. This second-generation W3 uses 21700 batteries, but it’s only a few millimeters longer. Its length is comparable to the Acebeam W10 or Acebeam W10 gen 2.

Even at this size, it can still be counted as one of the greatest LEP flashlights of the time.

Batteries and Charging

High power flashlights need high power batteries. Weltool knows that and includes a high-amp 21700 battery with 5000mAh, as it looks like. And you don’t need to be afraid of inserting the battery the wrong way because it has built-in reverse polarity protection. Often, this little detail can be neglected or overseen. Weltool is a professional manufacturer, although smaller than its competitors.

Performance and Features

Just to include all the most critical features and numbers, here goes:

  • A high-mode output of 505 lumens
  • A low-mode output of 102 lumens
  • Max distance in High: 1205 meters
  • Max distance in Low: 536 meters
  • High efficiency constant current drive circuit, no noise, and no PWM
  • Temperature control protection: when the flashlight temperature is too high, the flashlight will automatically reduce the brightness to prevent overheating
  • Reverse polarity protection
  • Low voltage warning
  • Battery over-discharge protection
  • Coated tempered glass lens
  • Passed a 1-meter drop test
  • Double O-rings to make it waterproof, (IP67)
  • Each flashlight has a unique serial number

From testing, we found that the W3 PRO isn’t reaching the claimed lumen output, but it is performing almost exactly like specced. I tested it at 363,000 cd while specs say: 363,375cd. That is probably the closest measurement I have done from all the flashlights I own.
