Default FS: 1.4 Watt 445nm WF-501B laser !

I have this black WF501B laser for sale. It has a M140 445nm diode, 3-elements glass AR lens, Aixiz module, aluminium heatsink, blue lenscap, buckdriver and two 18350 batteries.

The laser has a buck driver and it is set at 1.7A. It needs two 18350 batteries to operate.
The output is 1.4 Watt and with a G2 lens the output is 250mW more..
The diode has run few minutes for stability and power testing. I recommend 30 sec on/off.

I am asking $130 for the laser. That includes two 3.7V Li-ion 18350 batteries.
I can sent it world-wide but preferable in Europe.
PM if you want one or have any questions.

***the person must be 18 years or older and know the laser safety rules***






Add $40 for the G2 lens.

That is the normal output of M140 diode with a 3-element glass lens. The laser is perfectly fine

5 diodes from my projector were 1500mW-1600mW at 1.83A with G1 lens.
It's normal.

Congratulation for you. You seems have a good diode.
And what has it to do with this sale thread ?

Still available. A peek to the inside build, clean and sturdy !




Electrical conductive paint for extra electrical path to the host. The driver is already hardwired at the back.

Hmm that heatsink looks familiar

If you are using the same driver I am using in my latest build, here's some additional info for any buyers:

It's a highly efficient buck driver from DX, original output current is 1.2Amps, though can be pushed to far more with adjustements on the Vref line (adding 1x 1ohm resistor in parralel results in 1.7 Amps). By my measurements, with around 8Volts in (about maximum, or bit lower charge of two lithium ions), the driver will pull 1.08 amps (18350 batteries can handle a lot more than that, don't worry).

Assuming Vdrop of diode at 1.7 Amps is around 4.6 Volts, that results in driver's efficiency being around 87%, with heat dissipation of only 1W. I'm stoking these drivers up, because they are extraordinary reliable, powerful and cheap.

Seeing the build is well heatsink, duty cycle is going to be VERY relaxed with this laser.

Grab it while it's still there.

You own a 100mW green laser so I suppose you have a laser safety goggle. You must also know the risk involved in high-power lasers and over 18 years old.
These lasers are no toy, you must ALWAYS remember that.

If you acknowledge above then I have no problem selling the laser.
Within Europe money transfer is free of any cost if you use IBAN and BIC numbers of your bank account. I can accept PP as well.

Thanks, these are made by Eudaimonium
I like the buck drivers very much. Instead of using 1.7A from linear driver this buck driver only needs 1.1A. So less heat is generated by the driver and longer duty cycle for the 18350 batteries.
