Here's an off the wall qusetion for you;

I bought a red laser at the Home Depot. I can see the red dot on a white paper target at 100 yards if the paper target is in the shadows, or if it's very overcast outside. But it cannot be seen in bright day light.

Before I go buying a green laser to experiment with.....does anybody know if a green laser can be seen on a white paper target at 100 yards in broad daylight? (ie; they say the green laser is much stronger/brighter)

I'm using a 9X scope to try and see it at the 100 yard distance, but a red laser dot just plum doesn't show in bright daylight.....scope or no scope. In case your wondering, I'm trying to use the laser for the purpose of plotting a path of wind-flags out to the target.

depends on the wattage the ones we had in iraq you could see but i don't remember thier power

I think it takes a 20 milliwatt laser to be seen in daylight instead of the 5mw units that are available.

I've got a 150mw one and its definetly visible without magnification

It makes me wonder if the class of laser you had is off limits to civies. What's available to me in the form of a green laser pen-light is much the same and has a maximum rating. I suppose I can always contact one of the two thousand sellers on Ebay and ask. The folks there that offer a money back guarantee and have feedback to worry about would likely be truthful.

Yea.....that's the 5mw limit I see listed everywhere on ebay.

Then what's this claim they all make that the green laser is soooo much brighter then red...... if they are all limited to the same 5mw????

I think it's the color that makes a difference.
I've been told some of the chinese lasers are not 5 mw but are much stronger even though they are listed as 5 mw.
I put a cheap one on an AK and it is visible for only 50 yds or so in broad daylight.

The green and red laser are more than likely have the same power levels. Most max out a 5mw. What makes the green better to some is the ability for the human eye to pick it up better than the red. YMMV

that

I did further investigating on Ebay to see that 50MW lasers are available in much smaller variety.....and you have to look for them special in the search.They pop up in their own sub-store category. They seem to be in their own class of strength, and it makes me wonder if there are legalities with owning or using them.

It seems from the little I've investigated thus far,  that you have to be darn carefull that no kid or idiot ever looks into the beam. If 5w will do eye damage, I don't even want to know what the 50W rating does!!

In my experience it takes at least 50mw of green to be able to see it at 100m in broad daylight. And even at 50mw the dbals visible green is still hard to pick up without magnification, again i'm talking bright sun.

I have what was advertized as a 50mw "gun sight" from AIXIZ in Houston and it was visible on a normal buff colored target at 50 yards in bright sun, visible against green tree leaves at at leat 30-50 yards.  Never took it beyond that.  Power is the key as has been mentioned.  I no longer use it on a rifle once the novelty wore off, but still keep it, just in case I decide to use it.

Green is in the middle of the visible spectrum, red is near the end. This is why we see them better.

Ok....for sure we have determined that there are some mighty powerful lasers out there that can be seen on a target at 100 yards in day light. (when looking for it with a rifle scope). The standard stuff is 5mw (laser pointers and gun lasers), and it's too weak. I've already tried it, and there is nothing to be seen on the target at 100 yards. But, the 50mw and 100mw lasers will cause serious damage to the eyes. Because of this, I've already dropped the idea of using these 50-100mw things to plot wind-flags out to 100 yards.


If I leave one of these things unattended on a bench while I walk out to stake the wind flags on the beams path, I'm risking causing serious hurt to somebody. Curious onlookers can see the device sitting there on the bench, and out of human nature and curiousity stoop down at eye level to look right into the laser. At 50-100mw.....it will only take one second and they will be permanently blinded!

I bought a LS8200 12mw green Aimshot a few years back, and it's visible at 100 yards on a sunny day. They had also just released a 20mw at the same time. I went back last year to buy another one and they said the new law prevented them from being sold to me, so I settled for a 5mw (the legal limit). The 5mw is NOT visible at 100 yards on a sunny day. Too bad I cannot get another 12mw version.

They are durable, hold zero pretty well, and fun to play with, so it's worth the money as long as you don't expect to actually use it for self defense.

I bought a listed 5 mw green laser off of ebay a little over 4 years ago. It was TOO damn bright. I think it was brighter than advertised, as it was a chinese model. But, it was probably 10 mw at most...

Like I said, my only reason for wanting it was to be able to plot a course for placing my wind-flags out along a 100 yard target range. And like you say, anything above the standard 5mw lasers are just too damn dangerous to be using in this open manner. Heck, while I'd be setting up the flags, I'd be affraid of looking into the beam myself.......never mind some poor guy that doesn't know what I'm doing and possibly goes looking right into it!!!  Here's what I have since decided to use to mark a straight path out to 100 yards. Folks might trip over an orange string, but at least they won't go blind!

good idea...

try this

Their lasers get taken by the US Customs all the time, so you might not see for a long time or not at all.

It is because your eye sees green better than it sees red.  If both lasers put out the same number of photons, only different colors, your eye will see the green as about 2.5x brighter than the red.

10mw at 70 yards.





At 100 yards.

what about the K-15?

is it a good lower cost option, or junk?

Is that what it claims or is that what it puts out.... theres usually a very large difference.

Ok heres the deal since I just went through this. First for all the searching and potential headaches with customs and all that nonsense. you know where I found a great set of lasers that ship domestically... amazon.


Its very important to understand that the advertised power is almost guarenteed nonsense and usually quite a bit weaker although they can still be plenty strong.

the 5Mw legality thing is and is not the law. above 5 are legal to import own etc. etc. its jsut that they require a bunch of safety features that nobody wants to bother with. My understanding for this is that above that power, damge to teh eyes is possible due to your inablity to react quickly enough or block out enough of the laser with eyes closed. Some of the laser geeks claim that they do not become actually harmful until about 25 mw but fuck if im gonna risky my eyes of that so be careful.

** My advertised 50 Mw was still plenty bright but definately not near 50, it was closer to 16-20. bright enough to amaze people at night, but in direct sunlight not enought to do the trick.

My 100 mw which I also got on amazon for a whopping 17 dollars is somewhere above 35 iirc. Once you start getting a little more powerful you can do a bunch of poor mans testing procedures to get a rough estimate of the power that its making. Mine will cut through thin cheap black plastic bags. I beleieve that rates out at above 35. Its good no problem in direct sunlight to 70+ yards and 100+ yards easy during a regular day. At night its incredible, and enough to worry me about getting a knock on the door from the FAA if I shine it straight up.

the next one up I beleive its 50 or so plus and that will light a single match maybe withthe help fo a black dot.
above that your talking about lighting matches on contact , burning through papers and generally really rolling the dice with every using one with no eyebpro.


hope this helps.
