Default 2w 445nm handheld laser

Hello everybody,
I'm new here and I'm searching all the info that I need to build my own 2w 445nm laser. I just got my diode from ebay with the lens
1 5 2W 445 Blue Laser Diode in Module w Leads | eBay

445nm 405nm Three Element Glass Lens for Aixiz Module | eBay

Im wondering what driver and host should I use for laser. Can anyone find any good driver and host on ebay for me? I prefer to order from ebay because many eshops don't post to my country. Thanks

An X-drive is what I suggest. If you had let me know previously I could have put it in the package with your diode. Pick up a 1.8A one for use with that diode.

Unfortunatly there are not any hosts on ebay that I can recommend but there are lots of builders here that offer great hosts and ship just about anywhere and specially if it is somewhere that I ship.

Maybe check out hosts from Flamninpyro and he also offers the X-drive so you could combine for a single shipping charge.
X-Drive X-Boost
Flaminpyros Stuf

Also here are some more host builders that offer host kits.

Yes, I did almost the same build but in a C6 host, almost the same. If you get one of the Survival Laser drivers for an M140 I recommend this: Survival Laser Driver at 1.5A or 1.8A or make it a little easier and get this: DIY 445nm 1.5A Driver & Pill Module or this: DIY 445nm 1.8A Driver & Pill Module

Best of luck with your laser. If you want to see what I did with my M140 build you can see it here: Assembled a M140 in a C6 (pic heavy) Be sure to take photos to show us and be careful not to assemble the parts the wrong way and twist your wires (a common first time mistake) also point the laser in a safe direction when you first put the batteries in and screw on the tail cap, and avoid any direct contact with the beam.

Default Re: 2w 445nm handheld laser

Thanks, I have an another question. What batteries should I use for this laser? I prefer using 18650 batteries. Can I use 2x 18650 batteries? For this driver and diode? Or just 1x 18650 or 2x cr123a?

You will need 2 batteries. If you want to use two 18650 you will need to buy the battery extension tube: Battery Extension Tube- Black Anodized Aluminum otherwise you should use two 16340 batteries.

Default Re: 2w 445nm handheld laser

Not to step on Alan's toes but if the host will fit 18650s then it would make sense to actually use two 18350s rather than two 16340s.

Logic behind that statement here: Skylaser PL445 Battery Question

(backstory: the laserbtb PL series usually takes 18650s).

I thought about mentioning that but I didn't want to complicate things. In the Survival Laser hosts some 18350s will fit and some wont.
