Yesterday I received my new SF501B 520nm forest green 170-300mw laser from Sci-fi for 134$ without shipping cost.
Laser specs:
- PLP-520-B1 520 nm laser diode
- Power output 170-300 mW
- 405G2 / G9 / G1 (can't tell which one I have)
- 60 sec on / off duty cycle
- 2 x 18430 battery
- WF-501B host (black)
- The laser came in a standard bubble wrap package.
- The laser is assembled in the well know host WF-501B. I think most of you people already had this host in your hands. I choose the black colour because I'm not that picky and the black colour is a little shiny so it looks just perfect and the host came undamaged.
- The laser module sits tight in the aluminium heat sink, but the aluminium heat sink arrived wobbly and with very tiny aluminium filings that I cleaned right away. I had to adjust the top 2 parts of the host to fix the problem.
- I don't really know but I think the laser should come with a power certificate, because on the official Sci-fi website it clearly says it comes with the package. So I really don't know the exact power of my laser which I find really annoying. I emailed MrThejoker3 and waiting for an answer.
- I feel kinda bad for saying this but to be honest, the communication with MrThejoker3 was really bad. I took him 10 days to give me the tracking number which in the end turned out to be the wrong one.
The one I got says the package is on the way to Norway but I live in Slovenia. Very odd.

He said he got some IRL problems but still it takes like 1 min to send me the right tracking code. The conversation was awkward.
- The only thing that is bothering me is the green square around the dot when I point the laser on the wall. MrThejoker3 said it's because the way these 520 nm laser diodes are build. I know for sure that this is true for 445 nm lasers because the one I got from Blord has a similar fuzzy light around the dot but it's less noticeable because of the immense brightness of the dot.
To sum up the review. I think that the laser is just fine for the price I paid. The beam looks really good in the night sky and in the forest covered in snow. The cold doesn't effect the power of the laser at all and by focusing the beam I can ignite a match without any problem what so ever.
The next thing I need to consider getting it, is a Laser power meter, so I always know the exact power of my lasers that I will collect later on in my life.
Some pictures of the laser and beam/dot ( my camera really doesn't like the brightness of the dot).
