I received the review laser from Priceangels today, and here is a short review of what was in the package...
This is just a non-biased, honest opinion. As well as some power testing and so forth.
I went to the web site and I believe this is the laser that I was sent: (the box was marked 200mW's)
200mW 532nm Flashlight Style Star-Projected Green Laser Pointer with Safety Lock(1*CR123A Included) $30.36 Free Shipping
As shown in the above pictures, it came with an 18650 battery. But it must have been a mistake, because the laser does not fit an 18650.
It fits a CR123. An RCR123 is too long for the cap to close all the way. I got the same power readings with a CR123, as I did with an RCR123. (see below)
As with most green lasers, the battery installs 'case positive'. (positive end of the battery towards tail cap/switch)
The locking tail cap works good. The key can be removed from either position. (on or off)
The side button is sitting at a slight angle. Just cosmetic. Operates just fine...
Kaleidoscope tip:
The laser is fit with a rotating kaleidoscope tip that can be removed. It rotates for a nice pattern. Same as my tips that I offer for my DIY Green kit.
Power output:
I removed the Kaleidoscope tip to take some power measurements...
It does not really have a 'warm up' period. (I like that it goes right to the peak power)
It pretty much goes to peak power within 10 or 15 seconds. (normal room temperature)
It peaks at 62mW's, and is very stable. Slowly dropping in power during the 1 minute run, and settling at 52mW's after 1 minute.
The beam is very thin. I did not go into trying to measure beam diameter and divergence, but it is a nice thin beam just like the modules that we are used to getting from O-like.
With an IR filter at the aperture, the power is reduced by about 20%. From 62mWs' to 49mW's.
I can honestly say, that it performed true to it's marked output on the warning label...
<200mW's
It is definitely less than 200mW's.
John7788, the price of this laser at your web site is very reasonable. But it's a good thing that you are getting an LPM to test the lasers.
Because this it the kind of thing that can discourage sales in a hurry.
On the other hand, there are plenty of people who would be happy to pay $30 dollars for a unit like this. If it was advertised as a 50mW laser, then it would be great.
But when it is advertised as 200mW's, that is where the let down is...
Other than that, the laser is very nice for the price!
Thanks for sending the unit for review, and I hope your sales will do well with pre-tested units...
