Does banggood still offer the additional EDC flashlight? I didn't see it in the linked ad. Thank you.
@@highwaymen1237 They might after the flash deal ends in 9 days
@@FLASHAHOLIC_TV thanks for responding but I don't understand your reply.
Can you check? I will be using your link if so confirmed. Thanks you. In addition, I think your video is very well produced.
Should come with free binoculars.
Thanks for the show!
Not only are you doing some of the very best flashlight review videos ever. You are #1 at picking the background music. Perfect!
: - )
It'd be mainly Pink Floyd if it wasn't for copyright!
my god, flashlights have come a long way. i remember back when they were little more than dim little dingy electric candles. my dad and i loved building car engines together. of course, whenever things got tricky, i was put on flashlight duty and he would work away at the bolt head, scolding me if i ever let the flashlight off the mark. after i moved from home, we would try to work on engines whenever we could, but it obviously wasnt the same anymore. im glad i got this flashlight. now he can call me whenever he wants, and i can shine a light on his engine from my bedroom window across town. 10/10/
Don't buy a W4 for close up chores!
@@FLASHAHOLIC_TV the joke here was that i could light up the "chore" from the other side of town, but i appreciate the heads up :)
Lol! My dad gave me a hand crank WWII flashlight, still lights to this day.
The W4Pro is even more of an insane thrower. We have a local casino just outside town, and from an opposing hilltop road more than 3 kilometers away, I can clearly see windows on the top floors bathed in light. What's equally impressive is that the cars and ground floor underneath are almost completely unaffected. The advantage of having very little spill from so far away from these LEP lights cannot be overstated.
95% of the tune music during videos is annoying and completely detracts to what you’re trying to illustrate, but in this case... You make it seem more like a soundtrack to an epic movie.
You’re truly awesome in your taste and placement of music. Well done, sir. Well done!👏🏻👏🏻👏🏻
It’s actually to an epic game LOL. Elder Scrolls Online
@@Theboldrbetter good. Because I was think what is this oblivion like music
These LEPs are great to have when you're late at night in the ICW @25MPH and want to avoid crab traps, identify channel markers and stay 'within' the channel.
Yes, they actually do have a place in the real world.
Awesome review!
When you want to see tomorrow...today
Lol 😂 funny
😅😅
@@shadrachjackson752
YOUR IS CRAZY
😂
Next time you do long range like this, you should set up a camera at the area you shine, so we can imagine what it would look like to be lit up from that range.
I will when my team gets bigger!
So there is and upgraded version Weltool W4 pro tac which is 8 lumens more on high and boasts 3300 meters. From a side by side of the previous W4 the pro seems to have a bigger hot spot. Love to see your take on that FLASHAHOLIC. The pro retails around $479.00 US. If they can ever perfect these LEPs for wider beams it will replace LEDs just my thought, but that is a long ways out. I see Acebeams is back working on LEPs again so maybe they will be the one to break the 4000 meter mark.
The K75 is still badass imo!!
I have the K75 , along with the Maxtoch OwlEyes Pro, my Maxtoch is confirmed visible at 85 miles away.
It's great for star pointing or Elk hunting, but my K75 is just so much more practical!
I always love these thrower lights. LED or LEP. When your food delivery driver can't find your address, just tell them to look to the skies! And send out your signal light. :)
You just never know when you'll need to tell if that's a fly or moth on that fence post a few counties over!!! 😂 Great review!
and, Zap!
if you stick that on a drone im sure people would think its a ufo
Sweet light! I feel for the people in the farm house. They probably bought black shades for the windows
Rumor has it, that all animals on that farm are blind for some mysterious reason.
During the battle of the bulge in Belgium in 1944, the Germans shone huge floodlights at the underside of the clouds creating ‘artificial moonlight’. Now you can do that with a fn torch!👍
Purchased this afternoon... looking forward to my first LEP.
please update us about your experience after receiving it
I purchased a skylumen which is quite similar to nealsgagets budget lep. It’s killer! I’m eyeballing this one now.. it’s fun to touch clouds. Especially when there’s precipitation in the air. Using the beam on a ceiling will light up a room as well.
Banggood? You ever actually receive it?
I have received from BG. Everything I order. The W4 took a little longer. But QQ 😳
The intensity to the skylumen which is incredible but not nearly as quality build as the weltool is night and day.
I’m waiting on a fenix tk30 but not from bg. Seemed a nice size step down in size and ui, for an edc lep and for tactical mount. Skylumen. Get your feet wet decent price whitesaber I would take over a k1 because of size and intensity but I wouldn’t go dropping it or shock testing it. Decent ip 🐳W4 feels top notch though. Absolutely stunning, Exquisite light technology. Weltool in general. I have the t10 hr and hg with tail switches. Devil incarnate. And those are exquisite as well. If you are looking for exclusive tac. The w35 lep looks incredible but I’ve got the fenix coming. I will get some vids up soon. Choose wisely
911: what’s your emergency
Bystander: I think there’s an Alien on earth rn
After hitting the phosphor, the light emitted via fluorescence is not laser light. The light emitted by this flashlight is highly collimated and therefore has a laser like throw, but no this is not a "white laser"
A long range pointer. "you see that guy way over there?", "which guy" flips on the Welrod "That guy". "I do now".
Be a cool device to calm football hooligans down in the stadium or quickly point them out to Police if you are a ground safety officer.
That guy : who? Meee???
Gosh you're a nerd
If you dont mind blinding people sure
These are cool but I have to wonder, if the light at 160m is dangerous to your eyes, how useful or safe would this be for someone using this as a spotlight? You might risk frying your own optic nerve if the light refracts back at you.
No. But no one will want to look at it. The only damage you could do is keeping your eye open and staying at an exposed laser excited phosphor bead. It’s only doing damage because of the brightness not because of laser energy. However, if you look at how tiny the phosphor bead is, that’s the secret. Getting 500 lumen into the eye from a large surface of several LED’s is slightly different than 500 lumen from a 2mm bead. That density is what let’s this flashlight do it’s thing ultimately. However, if you aren’t looking directly at an exposed phosphor just a few inches away without blinking, you are fine. Accidentally flashing yourself or someone else won’t do damage to their eye, however if 500lumen from a regular flashlight scatters quickly, the LEP is the opposite, it will maximize output lumen much farther from the emitter. So whatever 500lumen is capable of doing to you at close range, an LEP will accomplish further from the emitter. The danger is somewhere between LED and Laser with the scale leaning hard towards the usual risks associated with LED’s.
I bet some people there are still saying "Aliens, everywhere!!!" 😁🔦
Awesome review and comparison 👍🏻👍🏻👍🏻
What this video showed me, is I don't need a LEP flashlight for my job. Unless I want to blind students in the dorms on my beat, indoors, with the lights on.
Can't wait for the Acebeam W40 and W50.
I as well. Any word on the ETA for the new w series?
The next day a dozen people reported UFO sightings and a bright light pieced through the windows.
No earthligns were probed during the filming of this review, afterwards however is a different story.
It needs a bit more throw.
Ha 😂
And spill...
Something wrong!?
“Indeed”
What is it?
“🤔 Yes...NEEDS MORE THROW!”
Just. Fix the foxus. Fix all exposure settings: aperture, shutter speed, ISO. Use Log-profile as more natural.
Using HLG3 now and manual focus.
I put my acebeam w30 battery in this and it seems to be brighter now.
So all of this light is made by shining a blue laser on diamond phosphor...WOW....could you make it even brighter if you used 2 blue lasers ? or even 4 lasers shining on the phosphor ? I just bought the w-5 and I love it!
I wish we could see what it looks like from the Farmhouse angle while you're shining at it.
would be interesting to see how strong the lamp is if someone filmed against the light.Can you make such a video. thanks for showing.👍🏻
Is it me or is the w4 unusable, the spot is too small, in what usecase whould you only need such a small hotspot.
My eyes!!! Law enforcement officer needs this.
Better to get the small osram white flat LED, its very cheap with super throw and you still get usable spill.
I would like to see a side by side comparison with the Acebeam W30 and this light...
I as well. I have the w30 and it is totally awesome.
That laser diode is being overdriven well beyond 0.25W. I mean that's fine if it's being cooled sufficiently. If the battery life is about 2 hours with an 18Wh battery, the input power is something like 9W! Assuming it uses an 85% efficient driver, the efficacy of the laser at that power would be around 73 lumens/watt. I guess the takeaway here is that this flashlight can achieve long distance illumination without a very large reflector.
yeah its good for low profile spotlights but not efficient power wise
I bought it now, with your discount code.
Thanks.
Enjoy!
@@FLASHAHOLIC_TV The flashlight has arrived, but I'm not happy with the purchase, I thought better. The spot is not circular on one side it is missing a slice.
Poor or defective product.
@@pitotopuk I think that's how they are
I bet ya neighbors loveeeeeee you..... Mine are going to hate me now I found this channel!!!!! LOL loved the comparisons
He's just moved out! I currently have no neighbours, yippee!!!
I love the throw on this bad guy
The K75 has more candela than the W4 and is not classified as a laser! How and why? I do own both lights and they are brilliant!
I've wondered that myself but it might because the W4 uses laser technology though some say it isn't
The W4 uses only a laser to excite the plasma, but the laser beam does not exit in any way. Therefore, I do not find the classification as a laser justified
Light Spill: And I took that personally.
I guess I'm just curious as to why there isn't an LEP that has a diverging lens on it for flood, rather than a focused spot beam. I understand how lasers and phosphors work, but I'd be interested to know how an LEP performs as a flood light, if it can even do that at all well.
There's a few zoomie LEP lights about but the focus isn't that useful.
Wonderful video excellent music. I wanna play Alan Wake again.
I recently discovered out how nice the Welly fits in an Astrolux FT03 holster. Closed bottom opposed to the semi enclosed from Weltool. A bit wide but if you paracord yours it’ll fit juhhst fine. Velcro fits over top nicely. .02 (if they run out of weltool holsters of course😘🤣 )
ruclips.net/video/Z2A-03UP-BI/видео.html for paracord wrap
Can this be used with night vision. Or will is just put black spots everywhere ?? And is there anything like this in ir ?? Serious strong laser 😮
Anyone else wondering what the people in the farm house were thinking when the flashlight hit?
"Omg, aliens!!!!"
Or
"Cops! Flush the stash!"
Why is the sun rising at 2am?
Police helicopter looking for someone lol
Weltool w4 vs acebeam w40 which is better ?
I'm not going to camp this year, but I got this so I can still play flashlight tag with everyone at camp.
Just reviewing the WP2 against it!!!
The eye of Sauron ...IN YOUR HANDS !!!
Alright bud. I’m posting this to me group. Join us. 😄
Lep’ers United
Amazing videos and work. Well done 👍
Would Make a good location light if you were lost.
I'm not sure if I could use one of these 'throwers'. I can't see very well and lighting something a mile away is no good to me. It is cool to have a massive light saber but practicality? dunno. Great video.
Please, tell me what is the reasonable usage of LEP flashlights?
Multi-range pointing/signalling, inconspicuous hunting, Long range sustainable search and rescue.
I am actually surprised how good the Astrolux MF02S did.
Awesome review as always, hopefully we’ll get to see a comparison between the w4 and w30. Keep up the great work man
Take a look to the channel of Michael searchlights, h did that comparison.
ruclips.net/video/sssaeZjrVXk/видео.html
Can't wait to shine this at speed cameras
I can imagine a powerful laser like seen on spyropyro can damage the camera.
3:10
I think their recommendation not to exceed 10 minutes of high is less about how hot the diode gets and more about the heat stress it puts on the phosphor.
oh. i figure it was to avoid setting the house they were shining it at on fire.
So just like a plasma tv that loses brightness, so will your $300 flashlight. Albeit more apparent than led that also uses phosphorus
@@Graciashauf of course. A new bulb will always be brighter than a used one. Even if it's $300000
@@daxshell242 it's not just the diode though. It's the phosphorus on the lens.... Why plasma TV's and CRT ones go dim over time. Phosphorus wears out.
@@Graciashauf Yes, took 100k hours to get to half the original brightness. AKA 11 years of non-stop use.
Which is the actual angle of the beam of Weltool W4?
Thanks
I've dealt with your Source for this video, posted a review, clean, polite, and truthful. They deleted my review! I asked in chat why they deleted my negative review... I was banned 🚫
Hello! Can you tell me how the Weltool compares to the Acebeam w30 as far as how it feels in your hand, the function of it, performance, or any other nuance I'm forgetting to list.
Love your reviews! Dontcha go changin'!
I have a question? What is the point? You can't search for people with it because if it shines their eyes they could take damage so I'm asking what is the point of this?
No usable point. This is just a demonstration of what's possible with current lighting technology.
I wouldn't even want this thing. I am afraid I would accidentally hit something reflective and cause myself permanent vision damage
That's Deadly!
Enjoyed the video/music, I bought one last summer and it is some light, Later from Texas usa.
Great review as always. I see the next problem as. How to make the beam follow the curvature of the earth.
I would like to have one. However, it would never come off of the shelf.
How hot does the lamp become, if at all?
A little warm, surprising for 400 Lumens
This is what Frodo and Gandalf needed in the mines of Moria....
Insane !!!! You could use 2 of these to light up the 9/11 Memorial every year.
These lights are pretty cool but what are people looking at from this distance? It seems like you can miss something a couple feet away. I’m not sure I would by one just to say “Wow, look how far I could see.”
I've bought a diffuser attachment for mine. Now I can light a whole yard or something 2000m away
@@FLASHAHOLIC_TV that sounds like a great idea. Some flashlights have a sensor built in to shut it off when something gets too close to the beam from some of the videos that I’ve watched.
That is bright! Lots of candela.
So is a light like this practical for use? I bought a Manker MC13 that I just got working has same beam projection it’s ok,it seems like this would be worthless or my understanding of how these lights are used is minimal which it is. I get more use out of my Olight Seeker2 than anything! Great vid as always
"Can cause eye injury up to 160m away"
Proceeds to point it at road and sidewalk 😮
hello who will shine next lumintop thror 3 or nitecore p35i. ?
I have the W3 and Acebeam w30. No prior light can ever hold a Candela to LEP.!
Acebeam K75 very good
been waiting for this one long time :D I knew you would review weltool
Took ages for it to come lol, It was in Turkey a loooong time for some reason.
What is the laser module lifespam compared to led ?
About 5000>10000 hours compared to 50000>100000
if you had to of course this would be pretty useful for self defence
I've always been a thrower guy. I think that the biggest attraction to these ones are the size and have always wanted a LEP. Would you say that the £240 they're asking for is a good price?
Seems a lot of money for 300 lumens but it's new technology I guess
I wonder what it looks like on the receiving end ?
great review I always like your scary place ending. This one was extra special with the guy singing and gunshots. Guess I like the light i have 2 the CW and NW tints. May sell one
Wow! Anyone help me to get this flash light.where n how to get it..............
Very good wow i want to buy this Astrolux MF025 V2 two units.How much each? I will wait for your reply! God bless you I'm from Philippines.
It’s very cool - but what possible real world application could this have?
For driving and people merging into you without looking
What is the point of such a flashlight? What should I use it for?
There is no real world use for such a light. Its only a too expensive toy and people will do wrong things with them like so many did with laserpointers.
Why do all the lep flashlights limit the power to 1/2 watt laser. Imagine how bright a 1or a 2 watt laser would be. Hopefully that will come out next year.
Dual LEP head exists for 4000m
Hi friends, I want to buy Weltool W3 Pro recently, what do you think of it？
Looks identical to the Acebeam W30, in both looks and performance, one of my favorite flashlights I've ever owned. I've got it slung under my AR-15 right now, its a laser at close range and turns into a spot light beyond that, I can sight on stuff at 1000 yards at midnight. Whats the cost? The Acebeam set me back $300 for the high CRI version, so I imagine this is around there...
AR-15 = noobgun
@@blob2092 people who call AR-15s noobguns= idiots.
which flashlight is the one that apeears first? The one that the spills hit the ryan's window?
ACEBEAM K75 I believe
how is it compares to ace beam w30
OK, now that's a search light indeed!
The W3 Pro has more usable beam due to larger hotspot.
Why didn’t they compare the W4 lep to other lep lights. The K75 is a different light.
Is it possible to use the lens on a 13000 lumen flash light?
this is good for night-snipers ?
I would prefer the Acebeam W30 due to its underwater resistance up to 100m.
I still can't believe the Acebeam X80GT can go to 30m, i keep meaning to make a lake vid with it.
@@FLASHAHOLIC_TV The X80GT is not a diving light despite its resistance up to 30m and the switch should not be used underwater.. The W30 however can be used as a diving light according to the description. 👍
People in the house : they are coming

Lmao I love that I’m a leper already , where I get one that I can see next week yesterday with
The technology is very impressive. But is there any practical application for a torch like this? I can't think of one.
You can signal people 22 miles away. Search the seas or open expanses for whatever. Search mountain sides for a prolonged time due to the long runtimes.
@Bad Goy hopefully a £5 chinese laser on ebay will appeal to chavs more. Not that i condone that either
This thing seems pretty useless based on the beam shots. Definitely a one trick pony. ☹️
That's with all laser excited phosphor flashlights though...
@Derrin Eckelmann That's still one use: being a high candela flashlight to reaching far. That's basically all it can do.
@Derrin Eckelmann Yeah. I love brass and copper torches and they are wonderful. It's the only reason I brought an astrolux s41 for the copper on it. I can't justify $350 on a one use flashlight that has no spill. I know I've got a problem with buying flashlights because I brought two of the same flashlights (mf01 minis) lol.
@Derrin Eckelmann - other lights throw just as far or further, and will light up a large swath of the ocean. Wouldn’t that make it easier to find buoys on the open ocean?
@Derrin Eckelmann - looking at the beam shots it seemed that others were lighting up the target more, with spill as well. I just can’t imagine that it would be easy to find anything with this light in the pitch black unless you knew where it was already. It’s like looking through a pin hole. Maybe for pointing things out it would be useful.
