100mW green laser sight on Ebay
 

$149+shipping. Personal correspondence with the seller verified the wattage. He also has a 20mW version for $89 (free shipping). You might want to get one before someone important finds out what he is selling. >5mW is not usually available in the USA.

Re: 100mW green laser sight on Ebay
 

Have you ever seen the beam from a laser of that color and power? It is extremely visible as such things go and can reveal your position in anything but full sun. OTOH, a red laser at 660 or 670 nm is hard to see in clear air unless you are looking directly down the beam and in dim conditions.

Imo, for practice or hunting in daylight a green laser would be fine, or scaring the crap out of a home burglar, but not for anything else that requires uncompromised cover.

It IS a good price though if the power specs are good.

No joke ~ that is a steal...........just checked and all other ones are 5mW or less like you said. WHOA

Re: 100mW green laser sight on Ebay
 

He even advertises his 20mW green laser as a 5mW for legal reasons. There may be others that do the same.

Re: 100mW green laser sight on Ebay
 

Ragnarok,

I've heard that 5mW green is a little too weak for typical engagement (65 meters) in broad daylight. Would the 20mW reveal a position? Would it be sufficient in daylight at typical engagement distance? I've never owned a green laser (but I have a 5mW on the way to my house right now).

BTW... a lot of people like to use powerful green lasers to demonstrate astronomy. You can literally point directly at a star.

Re: 100mW green laser sight on Ebay
 

You can purchase green lasers over 5mW in the U.S. but they cannot legally be used outside or in an environment where the beam could escape to the outside. Anything over 5mW can permanently damage human vision and that is why the restrictions are in place. They are a great aid in astronomy.

Re: 100mW green laser sight on Ebay
 

I thought the restrictions came into place as part of the war on terror. (?)

Re: 100mW green laser sight on Ebay
 

Yes, 5mW is not enough imo. Playing with that will answer many of your questions.

I have a 20 mW (atlasnova) and a 150mW green (optotronics) regular pen-style lasers, these are not built as sights but all of these lasers have similar guts. I bought them so that I could point out specific details on construction sites, etc., during daylight.

The 20mW spot is visible in daylight at several hundred feet, especially on a light colored surface, which is something else to consider. It cannot be seen in full sun; at night it looks like the star pointing beam in the above post. If you are working in clear daylight and against a dark target at a distance the 100mW might be a better option, but if there is any haze in the air at all the target could also observe the beam if looking in your direction.

The divergence spec is also important - how much the beam spreads out over distance. This can matter more than total power. Get the tightest beam specs you can - less than 1.5 milliradians (mr) full angle if possible.

Re: 100mW green laser sight on Ebay
 

The seller just got back with me and said he has the same product in a 35mW RED laser. Would you think this is a better all-around tactical laser? It is also much cheaper than the green lasers.

My application will be a 9mm SMG.

Re: 100mW green laser sight on Ebay
 

Well, you can go to prison for pointing them at airplanes and snipers like to use them, but there are also health issues related to using lasers. Frankly, I'm fine with them as long as you're careful. Some folks think they're toys.

From FDA:

The FDA recognizes four major hazard classes (I to IV), including two subclasses (IIIa and IIIb), of lasers--ranging from those that pose no known hazard to those that pose serious danger if used improperly. The higher the class, the more powerful the laser. Class I laser products, for example, include laser printers and CD players, which are not considered hazardous because the laser radiation is contained within the product.

Class IIIb and class IV laser products are very powerful and permit ready access to the laser radiation, which can cause eye or skin injury. Research and industrial lasers and laser light show projectors fall into these classes. Class IIIb and class IV laser light show projectors may be sold only by or to individuals or firms that have obtained approval from the FDA.

Re: 100mW green laser sight on Ebay
 

You can buy lasers over 20mW in the USA, wickedlasers has been selling them for ages.

The only catch is that FDA says they need to have a "safety lockout"--which basically means it must require pressing more than one button/switch to turn them on, to avoid accidental activations.

He is selling a few other sights too...
Are they any good at all?

Re: 100mW green laser sight on Ebay
 

I just bought this one. Price with shipping is $58.50. The Firefield green 5mW laser I purchased from OpticsPlanet was $59.00 shipped. I'll do a side-by-side comparison on them. I've read some bad reviews on the Firefield. I appreciate what Ragnarok said about red projecting a less visible beam in low light.

On the end does that say "Class IIIb"?

Re: 100mW green laser sight on Ebay
 

All of his feedback is enthusiastically positive... FWIW.

Re: 100mW green laser sight on Ebay
 

I own...5mw and 15mw green lasers

my 15mw laser dot is visible at 50-100yds during the day

at night the beam itself is somewhat visible due to particulate in the air, the dust etc in the air sparkles green revealing the beam somewhat

on a rainy night it is quite remarkable actually

5mw green is day dot visable out to 25yds .....and much less beam visable at night

in my opinion 15-20mw is appropriate if you anticipate a day light engagement
5mw is just fine for low light or night work....its been my experience that during daylight using the regular sites and your regular sight picture and window is much prefered to searching for a dot on something....of course at night you cant see your sights or get a regular site picture so that is when a laser seems most feasable.

so i am saying the highpowered lasers are much overkill because i see your reaction time to using them during the day to be much slower than using your normal sight picture and sights

now if you were planning on hip shooting a submachine gun during the day that would be different

Re: 100mW green laser sight on Ebay
 

My Ebay search brought up 313 green lasers being sold:

Lots of choices out there at all sorts of price points.

35mw thing for half the price:

Re: 100mW green laser sight on Ebay
 

Fyi it may interest some of you tinkerers out there to know that the laser diodes (red and violet) used in CD/CDR/DVD/BluRay drives can be made into very powerful pointers - well over 100mW in many cases; there are some forums that delve into these projects. The green lasers use infrared laser diodes + a special crystal/optic set to convert the IR to green (harmonic doubling) and are not really buildable by the average home hobbyist.

SLV, for sub-gun use, I'm assuming you're just wanting to see in daylight roughly where the rounds are going to hit, not precision targeting; the higher powered laser would make sense in that case.

For anyone considering a laser for use on a firearm: do make sure to get one that's up to the task/made for the purpose - while most red diode lasers are fine, most general purpose green lasers won't stand up to the recoil for reasons mentioned above.

Re: 100mW green laser sight on Ebay
 

here is a picture of a 15mw green laser ......projected on a cardboard box in a room lit to 50 candle power....which is very light

on two calico's with 100rnd clips...carbine and pistol....lil bitta gun porn :biggrin:..the rubber band on the K grip is triggering the laser

Re: 100mW green laser sight on Ebay
 

these two pictures show the green dot this time a 5mw at about 10ft...in a 30 candle power room and a dark room at the same spot

Re: 100mW green laser sight on Ebay
 

sorry for the multiple posts...

one important thing to consider is where you mount a gun laser

a good example of a poor location is how a crimson trace laser is mounted ...on the side of a gun and below the barrel...this means your laser is only targeted right at ONE yardage only......and other yardage's is is progressively worse in TWO directions...both side to side and up and down

a better mounting location is directly inline with the gun barrel either above or below.......again your only perfectly targeted at one yardage....but as the yardage changes your only off on elevation just like a optical scope...

setting up your laser can be a issue also.....since most lasers have limited or no visibility during the day....you have to have a range where you can do the setup at low light or at night...which can be difficult at best

just some additional thoughts if considering a laser

Re: 100mW green laser sight on Ebay
 

I sighted in my Calico this afternoon with the 35mW Vector Optics red laser. VERY NICE. It was much easier to see than the green 5mW laser. I was picking up the dot well over 100 yards in the middle of the day! I highly recommend it.

Re: 100mW green laser sight on Ebay
 

slv - very cool! I'd love to try that out.
