Ok guys the following will be a review of the O-like "400mW" 405nm Adjustable & Waterproof laser:
This laser came friday and is a little gem of a laser.
As you can see it came intact from Hong Kong with a nice little box with foam cutouts and to my surprise an Ultrafire Protected 2800mAh 18650 lithium battery.
As you can see the host is beautiful and has no stratches or blemishes and the threading is exellent. The tail cap screws on very nicely and snugly and has a rubber retention ring. Both of the laser's contacts are springs but with this unit its always "+" end of the battery towards the tailcap. There is absolutely no shaking once the battery is loaded in and the tail cap screwed tightly on. This laser has a very easy to operate rear clicky, which a very nice dustcap installed.
This laser is an exotic purple beauty. Very nice tight beam when focused for long range, and a clearly visible purple beam, these pictures are taken with an I-phone camera, with no added effects, no fog or smoke added.
As you can see I provided a picture of the laser's dot filtered through my goggles. It is a nice oval at close range and a more circular at longer ranges. This laser has no artifacts around the dot, which is very nice. It also helps me prevent identity theft by quickly, easliy and permanently redacting any documents or receipts before throwing them away.
And now for the power measurments:
This laser is rated at 400mw; however is capable of so much, much more:
For this run the laser started out at about ~510mW and quickly exceeded 560mW, reaching a peak of 568mW. As you can see from the laser's upward trend, it would have easily reached 600mW if left running for longer than the 75 seconds metered here, but as susie says:
I didn't want to keep it running for longer for fear of affecting the diode's lifespan as these lasers have a 60/90 sec on-off duty cyle.
So thats it for now, I hope you have enjoyed the review, please post a response with any additional questions, pictures or tests you would like me to run :yh:
Regards,
Sal

laser: pls respect its duty cycle
