Re: WANTED: 1W 445nm laser for about 100$
I have a very poorly built (I didn't build it) 445 in one of the waterproof Rayfoss hosts, that I would sell for $75 plus $20 for tracked shipping.
I think this came from someone who had sold me something that didn't arrive, and it was part of a "make-up" for the non receipt of the original purchase.
It has some sort of LED driver, with black electrical tape insulating the sides of the LED board from the inner walls of the host. The driver isn't fixed in place, so it's held in place by the battery itself, meaning that you have to be careful when you change the battery to make sure the driver hasn't shifted. If it has, you reposition it with your finger before putting the new battery in. Also, it requires a magnetic spacer in order for the 16340 to fit. It has three modes (I think), but I haven't really figured out how they work. Sometimes it hops modes (which I think is due to the magnetic spacer momentarily loosing contact. It would probably be greatly improved by soldering a spring onto the tailcap instead of using a magnetic spacer.
It's this host:

All things considered, it's actually a fun 445. I haven't really thought I could sell it, on account of the above, so I haven't really known what to do with it for a while. But I've enjoyed it myself, largely for its weather-proofness. It's great for a camping trip, or use outside in the rain.
Anyway, I would sell it for $75 (subject to all of its faults), mostly because that's basically the cost of the diode + host + driver + lens + module. In other words, if I just took it apart, that's what I'd have in terms of part value.
Not sure of the output, but I could LPM it if you had any interest. It's probably in the power range you're looking for.
