When I first saw these, I went 'why not?' so I ordered three. They finally came in today so I figured i'd do a review for anyone else that might be interested.
To start with. Here's where to get it.
Focalprice.com offers 50mW 532nm Green Laser Pointer (Black) ,discount 50mW 532nm Green Laser Pointer (Black),50mW 532nm Green Laser Pointer (Black) products,low price 50mW 532nm Green Laser Pointer (Black),cheap 50mW 532nm Green Laser Pointer (Black
Some basic specs and info. These use 18650's. The hosts are labeled XX-852 on one side of the barrel and 'Green laser pointer' on the other, and they come with a wrist strap. The clicky tailcap is different that what's pictured on focalprice and the contact side is mostly flat, but it's still raised enough that flat top 18650's will work. Battery goes + towards the tailcap. The usual orientation for green and IR's. The threads on the host suffer from usual chinese QC as well, but nothing horrible. Get a brush, clean all the aluminum chips out of them and grease them a little and they'll be fine. The label is accurate on these, and doesn't have the wrong color or wavelength printed on it.
These also come no-frills. A laser in a white box. Mine had no bubble wrap or anything else in the box. They were just in white boxes, rubber banded together in a big envelope with the three sets of goggles I ordered as well. I'll review the goggles tomorrow after I test them a bit more.
Next, here's probably what everyone wants to see.. real numbers. I didn't have the camera handy this morning to get LPM shots when I metered them all so you'll just have to take my word for it.
Laser #1: 37mW 532, 36mW IR, 73mW total
Laser #2: 15mW 532, 10mW IR, 25mW total
Laser #3: 26mW 532, 24mW IR, 50mW total
These are the 'stable' numbers, not 'peak'. Green was measured by getting the total measurement, then putting a pair of OD4 532 goggles in the beam which just left the IR, then subtracting that from the total.
Disassembly:
These come apart REALLY easy.. if you do it in the right order. If you don't, you tear all the pins off the IR diode..
Ripping them asunder.. if you will, is pretty simple. First unscrew the tailcap, then get some type of hook or reaaaly long needle nose, and fish out the black foam ring, plus the two white foam chunks that are wedged around the driver. Next, unscrew the top cap, then unscrew the module from the host.. that's it. If you don't remove the foam first though, when you unscrew the module, you'll find the driver still firmly stuck in the host, and you'll have a green module in your hand with a diode with no pins. :undecided:
The module/driver:
Fairly typical. The average 12mm 532nm module I see on ebay all the time. The switch is jumpered to be on all the time.
In conclusion:
(taken with a moderately long exposure of laser #1 in a dim room with no smoke)
Do I think they're worth $15? Definitely. More heatsinking and a LOT longer runtime than a pen pointer. The host, while not being anything special, isn't really a piece of crap either. The 12mm module could be swapped out with an aixiz module with minimal industriousness if using a similar length driver as the original IR, so these hosts wouldn't be hard to repurpose for other lasers.
They aren't super high powered, but they're $15 lasers too... It's kind of like the $9 405nm pens.. For the price... Why not?
