cheap vs. expensive lasers

Post by FSNTAC » 22 Mar 2009, 06:22

I am seeing some lasers in the 20-30$ price range.
What are the pros and cons of these compared to the lasers that sell for 200$ plus?

I am no expert on lasers, but with some personal experiences and reading some feedbacks on cheap and expensive lasers I say is you pay for what you get.

The red lasers are fairly cheap these days. The green ones still cost a lot but are better.

The extra $$ you pay for a high end laser is so that it will stay zeroed, i have never seen a cheap laser hold true whatsoever.

Read up on IR filters and ruggedness. I've seen posts on lasers that wouldn't adjust, break after a week etc. Of bigger concern is the IR safety issue, especially in the higher output green lasers--red lasers are generally safer.

I am not a laser geek nor do I play one on the web, so here is a link:

Many of the cheap chinese lasers overstate their output by omitting the IR filter and measuring the IR in addition to the laser output. This results in a more dangerous, less bright, laser. Having stated that, I have a very inexpensive green laser that I will install an inexpensive filter (not cheap, they just don't cost that much) in and will have a very bright green laser that is safer.

Having known then what I know now, I may have opted for the brightest red I could afford. The green I have is like a light saber, you can see the beam (not just the spot) indoors no problem. I haven't tried it outside yet, but don't think I will have any difficulty seeing the spot at great distance, not sure about the beam.

Here's a web blog on the subject worth reading:

high end lasers are easier to zero, hold their zero, and the battery life is extended.

I DO NOT RECOMMEND CHEAP LASERS, please learn from my mistake.

Sort of like the nice looking cheap flashlights. Look good and tuff but don't always work. I have gotten a few of the cheapy lights and lasers from others to try and make them work better.

I think the best way to put it is, If your life may depend on the use of an item. would it be worth the extra cost for quality?........Hal

I have made the mistake of purchasing a cheap green Chinese laser for about a hundred bucks. It was pretty big. It also stopped working very shortly after I got it.

Id spend the money on proven quality.

What are you looking for - red, green or IR?

For those people who like to work in the dark, there's a good thread over at arfcom on building a reliable IR unit by replacing the laser module in a Beamshot 1000 with a commercially available IR diode. Pretty much plug and play.

I won't trade in my DBAL-A2, but I've got the bits ordered for this one as a candidate to mount on a S&W P99 .45ACP for "housework".

Powerful lasers have a "duty cycle" limit depending on the heat produced and the quality of the diode/heat sink. Keep that in mind if you are going to buy a powerful Chinese laser, they may have been pushing the diodes well past their cooling ability, limiting the laser to 1-2 min bursts before needing 30 seconds to cool. You can make a pretty good burning laser with just a DVD burner diode, a penlight type of case, and lots of button cell batteries, but to avoid burning it out you would need to keep it to 10-20 second bursts with at least 30 seconds to cool in between.

Also, +1 on the IR filtering deal.
