Great light!

Killzone was great about getting the order out quickly and following through with shipping information. The W3 Pro is a small LEP but puts out a fantastic beam. Even at just several feet away it does not white-out the object in its beam. That is a BIG plus to me that I could still see the details in the beam at that close range. The beam is big enough to give an overall view. The beam goes farther than any far range I shined it at. It's not a light to go walking through the woods with but if you want an additional light that is easy to carry too, this light allows for seeing far and through the trees. To me it's the most practical and quality LEP light out there.

Powerful. Solid. Incredible.

Off the top, I really like Weltool products - Weltool commits to quality manufacturing across the product line. The W3 Pro is my first LEP and does not disappoint. I enjoy different lights but do not know all the terms and variances for those seeking a technical review. I live in the country and it suits our purpose and price point for spotting. Being in the country we have minimal light pollution so I imagine the beam and spot is even more pronounced than some users experience.
Lastly, the customer service provided by Killzone (Jody) is second to none. Knowledgeable about the products sold and lightning fast in response. If there is a light I want or need and it's sold here, I'll purchase from Killzone over other local or internet resellers.

Weltool W3 pro

This thing is badass. Practically, peace of mind with batteries. As illumination or signal, this is for me. Now I need to find a holster, filters, extra battery and I'll be set. Other than that, its everything I expected and more.

This light exceeded my expectations. Super high quality build and the brightest, tightest beam I have ever seen.

This flashlight is incredible. Just absurd amount of throw, you can see the whole beam like a spotlight. Its very well wired because it doesn't get too hot, definitely built as it should be. Haven't played with it too much to determine run time but I am really pleased with this light. If you want a hand held thrower that will impress just about anybody, pick this thing up. It is a very cool light to have in the arsenal.

Great compact LEP

Weltool makes very well built and no nonsense lights.
This no exception.

Its one of the most compact LEPs on the market and with the 18350 tube its the most compact hands down.
I got this because its small enough to easily belt carry but still as a massive candela output.

Very satisfied with the light and, as always, Killzone's shipping was lightning fast.

Discreet illumination

The only way to throw light without drawing attention. Build quality feels great, and the simplistic button function exemplifies the tool aspect of WelTool. The lens cover is a very nice inclusion as well, which I don’t think the other brands include.

Joseph G.

Fast shipping. Good follow-up. Great product. This is the pocket-size thrower I’ve been waiting for!
Any farther and I’d need binoculars.
