I wouldnt say useless. You could easily start a fire if lost in the woods! Or signal rescue if lost in the woods! Or point out constellations in the sky! Endless possibilities for this thing. At least that's what i told my wife when she asked why there was a $60 charge on the credit card. 😉
@@Jeeper906 self defense is also pretty effective usage for lasers of class 3,4 since once u point one of these at ur opponent eye it will do permanent damage meaning instead of the opponent going after u once he been damaged by laser that would pretty much give u time to flee and run away or even finish the job if u want to go that way so
@@Dav624 I've often considered the idea that a laser packaged in a traditional tactical rifle style form with adjustable lens and integrated computing components for object identification and automatic aim/targeting would be one dangerously effective platform. Highly illegal and would break every conventional international arms agreement, but even with current commercially available components you could potentionally have the ability to focus near kilowatts of laser power into a relatively small point within a hundred yards with only a handful of people...
@@Jeeper906 I got a 1W (wicked lasers, back when they were the only option) blue laser for heat shrink tubing in areas that were heat/dust sensitive and couldn't have a heat gun blowing hot air around. Worked amazingly well. Used a modified dental mirror with a first surface reflector to get the back or bottom side of the tubing.
Be careful. I have been using high powered lasers for 14 years and I have permanent eye damage from these and I don’t know how or when it happened, just a spot in my vision all the time, but I know it was from one of these blue ones. Even looking at the dot on a wall will cause it. Blue is particularly bad.
@@Six6ix Yes, I have glasses specifically for these, but I must have either not one day, or maybe I saw it through a gap, not sure. Damage can take weeks to appear so I really don’t how or when it happened. I’m sure the glasses work, I just assumed I messed up somewhere.
I love my Sanwu lasers, all custom made.I’ve got three silver series 1.6 watt 525nm green laser, and a 4 watt 450nm blue and a 1.2 watt 525nm green laser. Little pricey but the laser output usually run a lil more over spec. Catch stuff on fire like 20ft away. It’s a blast
Another Sanwu collector! Dude I love Sanwu, I've got a 1.1W 525nm green, 5.2W 470nm light blue, 1.2W 650nm red, 500mW violet, and a 150mW 488nm cyan. I blew my wallet up getting them but I'm glad I have them lol. I'm really mad at myself for not saving enough when the RGB was still available, I'm really wanting that one. I've got the money now but they aren't available, that's irony in action...
EXCELLENT REVIEW!!! at the beginning I thought you''re probably doing the review for a cut of the profit - but your 100% sincere critique about it's shortcomings (which are negligible but still valid) all made perfect sense... like the burring, the lube & the lack of a polarity sticker show that You have enough knowledge & experience in the field to be anble to present a well informed opinion to your audience!! Thank You!!
I had one of the $60 long, black, blue high powered lasers ordered on Amazon . I just cancelled the order before they shipped it, and ordered one of these. I am very excited.
I think what scares me the most is the eye protection. I do not trust any of my glasses since I don’t have a way of physically testing them. I have two laser cutters/engravers and I’m so paranoid that I cover it with a large box while operating.
Yeah I'm going to have to order a few of these lasers, I'm looking at this blue one and the 405 700mW, I love me a good violet laser. Thanks for the recommendation, I'm a big laser hoarder and have never heard of these guys before, and I'd much prefer to give my money to the Canucks (😉) instead of some Chinese sweat shop. I've got over a dozen lasers in nine different wavelengths but I just can't resist something new and different lol.
@@NullScar yep, I've got full spectrum protection, I've got five different pairs that go from 190nm UV up to 11,000nm Co2 IR from Sky Lasers. I play with some bigger lasers, they are must have items. I've had a few whoopsie moments over the years that would have flashed my retinas if I wasn't wearing them...
@@TheExplosiveGuy Thank you for your detailed reply! Also, I only have one laser. I believe it is similar if not the same as the green laser in the video. I don’t wear safety goggles when testing it, but I am aware of the refractions while testing. I really want to show my son but I am afraid to do so because I don’t have the correct knowledge here. Should I buy goggles for children if I do plan to show a bit more of my green laser? Pretty sure it is the same in the video.
@@NullScar hey no problem. I would highly suggest everyone have goggles, it doesn't take much to cause permanent retinal damage with lasers. I wouldn't go too cheap on them either, and make sure they're in the right wavelength for your laser. If I remember right a decent intermediate set of goggles should cost around $50.
I think that the host body is from a basic china made flashlight. I have one exactly like that with the same click boot, lanyard hole and everything. I think that maybe that is how JL Laser is keeping the price down on these. I am not knocking it at all......I have always loved the shape of the cheap china light that I have.......and I will prob be picking up one of the JL Lasers as well. Thanks for all of the really thorough info.
Kudos to you for the emphasis on safety. Potential buyers should be considerate of wildlife & pets as well. Don't point the laser at trees where birds may be perched. Great review!
Be super careful running your finger across fresh cut threads. I have a small piece of metal in my finger to this day because I ran my finger across some freshly cut thread about 15 years ago. (There was a piece of metal in my finger and I pulled it out, I didn't realize at the time that a small piece had cracked off and was left behind)
I want to point out that that's some damn good information and thanks for the advice if I buy one of these things cuz I'm probably going to get myself in trouble I shouldn't even look at this but thanks for the tip about the glasses
@ballpenkennjohn3129 oh, it's out? I had completely forgotten about it tbh. Thanks for sharing! I might go buy one. Unless I see a 5W 465nm laser coming soon next to it. 🤣
Thanks for a very informative demonstration and description of these devices. I’m awaiting a few to arrive: Many Thanks to you! 😎 My big BIG Question is what brand, model number, OEM or vendor makes the Laser Power Meter (LPM) you used to so measure laser output power with a thermopile sensor??? I want a portable LPM just like yours {Affordable I hope 🙄}!!!!! 🤓….Bruce Wms
I don’t know why you stress it so much with safety glasses especially with lasers of about 100-200mw I have a 150 mw 492nm cyan laser and I use safety glasses only when burning things and I still have my vision fully intact
Can’t find any credentials or information about JLasers anywhere. No talk in forums or anything. And he’s on vacation for a month. I’m wanting to buy one but too skeptical.
Amazing review! Is it ok to look at the beam of this power when it's pointed in the night sky without safety glasses? Would it still be safe as long as it doesn't hit an object or directly look at the spot if lets say you hit a tree at a far distance? Or must you wear safety glasses whenever you're using it no matter the situation? Thanks for any reply.
Good question! The scatter in the night air is completely safe to be looked at with your naked eye. If there is any possibility that the beam will reflect back to your eye directly (by accidentally hitting a metal or mirrored surface) then laser safety glasses should be worn. Even a fraction of a second of the beam entering your pupil could mean permanent eye damage. But in summation, I don’t wear safety glasses when I’m using it outside, but I’m carful to avoid reflective objects and airplanes.
So you can look at a laser beam from the side right? You just can’t point it in your eye if I understand correctly. So you could hold the laser and shine it up at a cloud or some thing away from you and not damage your eyes or are you actually have to wear glasses when you do that?
Yes, if the beam of pointing away from you and you are looking at the beam’s scatter, you will be fine. But, this beam is so intense that if you had the laser pointed at a nearby wall (within the interior of a house for example), I would still wear laser goggles to view the spot. Shining it at an object outside and 100’ away from you would be safe.
I wouldn't recommend it. The light is so intense in the house whenever you hit a white surface. And don't hold it in one spot for too long or you will leave a burn. The table I'm sitting at has a laminate surface with a burn in it from playing with cheap ebay blue lasers. Cheap price, but decent quality for what little I paid.
I have a pair of cheap ebay blur lasers. One is the Thor II. The other has no name. Both are very powerful. Dark balloons, matches from 15', all the fun stuff. While setting everything on fire I had a neat idea for the 4th of July. Fireworks will ignite if you hold the beam steady enough. Wasps on nests don't like them. One of the coolest things is hitting stop signs, street signs and license plates blocks away. They really light up because they are reflective. Other than that once you play with them for a while they sit around. I thought about keeping one by the bed for non lethal home defense.
In the night shot, the camera shows the 1.6W JLaser at almost the same brightness as the 5W Blue laser. Is this how it looks in real life too or is the 5W Blue laser much more bright & Intense than the 1.6W Blue Laser?
The body of the laser looks different on their website. Are their pics just wrong? I'm asking because I love the look and want to make sure that's what I'll receive.
@@cheule Thanks man. I appreciate everything you do for us light hobbyists 👍. I use your videos to help so many having issues understanding Anduril2 since you are really good at explaining things 😀
@@Patriot87Travel I believe it's the 1.6w blue one. The pictures look a little different but that's the one shown in the video. Really hoping that's the correct one which I'm pretty sure it is as it's the only one with the same specs as in the video.
People are mad that some flashlights are lighting their pants on fire i cant imagine what a pocket laser like that would do hah i still want 3 of them though
The beam divergence on that 5W 450nm is horrible, the beam is so thick it's practically a blue laser flashlight. Is that some kind of safety feature so you don't accidentally burn stuff or is it missing a lens or something?
When I’m using a laser to point out objects in the sky (like constellations) I do not. But if there is any chance that you might reflect the beam back at your eyes, you should.
When you shot the laser into the night sky, why did it suddenly stop at a certain distance instead of just fading as the distance increased? It looked fake because of that.
It’s called the boundary layer. Flashlights do that as well. Particulate matter is what makes the beam seen, and there is a defined boundary of particulate matter. Above that the beam still exists, but doesn’t scatter back to our eyes.
@@cheule OK, that would explain why it didn't show any reflection back to our eyes above a certain altitude. But you moved the beam up and down and the maximum visible beam length didn't get longer and shorter. The particulate "ceiling" would logically be at about the same altitude causing the beam to lengthen as you moved it more horizontal. Just trying to understand.
@@patriotclint395 It is also about angle of view, if you saw from the side, you may notice the beam go into the clouds or the horizon. But when you are behind the beam, at some distance the tip of the beam is so in front of you & you so behind that you cannot see it extend any further. It is like pointing your finger in front of you - at some angle you cannot see the fingernail.
I’m a house painter and just need one for pointing at things on houses. The dollar store one isn’t powerful enough to do squat with outside. Any recommendations?
Look for a green laser.. Because of the way our eyes work, we see the green far better than red or blue. A cheap $20 505 green laser on eBay will most likely arrive at between 50-70mW, and will be easily visible even in daylight at a range up to 50 feet. If that $20 505 laser doesn't satisfy you, then I would go with a 1W+, but then extreme care should be used because of it's high output.
You never hear anybody talking about lasers being used as a self-defense weapon that seems like it would work if you had somebody attacking you and you pointed it straight at their eyes
@@arrow2042 Blind the attacker & then send him to God. Now, if you have a huge mob attacking you, use the laser to blind/startle them, run away & then maybe use the gun on anyone unblinded or still tracking you. A gun can never have enough bullets to take on a mob - but a few quick swipes of a high power laser can blind them enough to give you time for an escape.
it's not a self defense weapon. By the time you aim it right, your opponent will finish you off, and probably take your toy too. If you do manage to strike, it will probably be one eye, and they will be furious, and do more damage to you. If by some chance you manage to strike both their eyes and disable them, depending on where you reside, you will be criminally charged and be liable in a civil suit. So, not worth it. Like the man said..deescalate and get out of the situation.
I built a 6 inch diameter 1.7 million watt laser in my garage to see if it would work. Well, the first thing I used to see if it worked was a 3 inch thick by 10 inch square piece of hardened steel. When i turned on the laser for only 1 second it left a perfect 6 inch diameter hole right through the steel, unfortunately it also put a 6 inch hole through my garage and through my car door in only that 1 second. None of the interior started on fire I turned it off before that happened. I will be testing it later to see how thick of a piece of steel it can go through at 1 mile out in the desert. I tell you how it went.
Whether it is white or black shouldn't matter. It will only affect sensitivity. White sensor will output lower voltage at same laser power level than a black thermopile. The important factor is whether the white coating/surface reflects/absorbs equally across all measured wavelengths. Colored thermopiles would not work, but black or white, the only difference is output sensitivity.
I heard from Jim at JLasers that: 1) he ran out of all stock and had to wait for more to arrive 2) that the new lasers will be even better. Apparently he has a upgraded driver. If you’re worried, I’d shoot him an email.
How far will the blue burn? Dunno if I'm wording it right. Is there a distance where it loses it's energy and has no effect? Can it be magnified? Just askin!
Depending on focus, and the color and type of material, a high powered laser like this can melt something like electrical tape from 5-8’ away. But realize you can also get permanent eye damage at extremely long distances.
You're doing this at night when some 10-year-old is probably looking out their bedroom window and thinking there is absolutely huge lightsabers having a fight in his backyard right now this is absolutely hilarious and you should use the lasers as such try to have a sword fight with them in the air (obviously I mean make the beams themselves cross like there was a fight I don't actually mean you and a friend potentially destroy your eyesight having a laser sword fight) and really mess with people this would be funny on a level that I think we could all appreciate
I ordered one and it has been over a month and still have not received it or even heard anything from them how long did it take for you to receive your laser?
I know Jim of JLasers is still putting lasers together to fill orders. Apparently he’s even upgraded the pill design since my video, so you should be getting the new design. Did you reach out to him yet asking for an ETA?
@@cheule Thank you for replying!- yes, it would be big & look a tad funny, I have a little 303 that I unscrew to take one 16340 battery instead of one 18650, basically makes it half the size, then I put the Sanwu 3X beam expander on it, and it makes the laser look even smaller. Lol
Perhaps, but floaters are dead rental cells that have sloughed off the back of your eye and are now trapped in the vitreous humor of your eye. I'd expect a laser's energy would cause scarring rather than floaters. But all I know from how eyes work is what I learned in college Bio, so take what I say with a grain of salt.
I absolutely loved this until I noticed you can only run it 1 minute then 5 minutes off with the stronger ones only having 30 seconds on and 5 minutes off. I'd love to see a green pointer with 5 watts that run continuously AND NOT COST A MORTGAGE PAYMENT still want one of theese....lol
Are these lasers strong enough to damage glass? Are there ones that can go through glass without damaging the glass, but can ignite or damage other materials? Also do all these lasers shoot only a narrow beam that stays the same width throughout the entire length of the beam? Are there some that can widen the beam and increase the width, the farther it goes outward like a flashlight? For a flashlight like that I would want 1 that cannot ignite and damage things.
Have you looked into LEP flashlights? Kinda sounds like what you're explaining. An affordable one that I've been looking at is the Lumintop Thor 3. For even cheaper, but worse preformance, look at the Lumintop Thor 2.
Depends on what you define as "burn". If you want to light fires on wood and cut white plastic or paper you need about 5 watts, if you want to cut electrical tape a 50mW would technically work _(veeeeeeeeery slowly)._ If you want something that fits somewhere in between 500-1000mW is a good number. This laser in the video is quite a bargain, I'll probably add one to my collection, if you want a decent burning laser you can't really beat these ones.
@@doubledome2076 will it ignite a flame on the wood? I don't have anything in between 1 to 5 watts so I don't know the exact wattage threshold for flame ignition...
Well, I’ve stated such in the video several times. I feel like that should suffice. At the end of the day, if someone is going to do something dumb, I don’t know if a warning message would have stopped it.
@@Stefan24971 - Yep, industrial metulcutting lasers are powered and cooled from big hardware in a boxes, but it's possible to power it from portable batteries and cool from a big radiator for a few seconds per minute cycle.
People frequently miss the whole animal with firearms as protection. Same with mace, it’s hard to aim when needed, I’m not testing out whether I can hit the bear directly in the eye with a laser when he’s charging 😂 Another point, you wouldn’t want to permanently blind the animal as a simple deterrent either, as it would likely starve if it can’t see.
They would not make a good weapon because it's a tiny point. People use green lasers to scare off geese which is why I wanted it. I never point it physically at them because that's animal cruelty but it's fine to just point on the grass to chase them away.
DPMM lasers are, and they are much stronger than other types of hand held lasers. There is a lens system called a beam compressor you can use, but I actually prefer the look and weight without it.
I’m very conservative in my views and normally I say we should have access to most things ….this laser frightens me….simply because many people are really damn irresponsible and I personally would have to kill someone if they were messing around and blinded me as a innocent passerby
Sounds like someone's trying to fight the urge of buying one lol. But in all seriousness, I don't care who is holding the laser, I won't and will not trust them. Doesn't mean I'm not going to buy one though. I'll just be overly cautious and handle it like a rifle with chambered round and defective primer. You can't predict when or if it'll fire.. Just as you can't forsee every possible reflective interference.
I think you’re here for the comedy-but I’m case you’re being serious, most high power custom lasers are much bigger. I believe I show some others in my video.
@@cheule Yes I converted the Subscribe to Unsubscribe, and gave a thumbs down The fact that you are arguing and calling me a liar, means I made a correct decision Take Care
Those are garbage multididodes lazer, single diodes are much expensive at fine dot, not oblong no matter how far it travels still will be a dot. But those are 3 x more expensive.
