1.8W - 2W Laser (DIY?)

Was wondering does such laser exist? I am interested in getting one, just realise my Spartan 1W is not strong enough, looking forward to a stronger burner.

Seen some people postng about their diy but not sure if it is available anymore. Wondering is anyone is selling their 2w laser?

Check DTRs reviews in his sigfile.... they are the best on LPF IMO. He's not selling anything 2W as far as I know but his reviews certainly cover anything you're looking for with this power

You can push a 445 to just about 2 Watts, but it is at the diodes limit...

Here's a host/driver combination that can go to 4 Amps if you need:

In the thread, I mention a Maglite 2 D host, which I like better... It will use 2 X 32600 Li-Ions with a FlexModP3 driver... (or if those batteries are not available, 2 X 26650's with a custom sleeve and a tail cap mod)
