I'm on my fourth... hehe I will post some pics when it arrives.. I really love these and the mits 110's you are selling.. These single modes are alot nicer than the others.. and if I was to choose from a 445 I would go for the h1600 In my own opinion it rocks the socks off the other 445's. In a copper module and 1800 linear it breaks my 2.5W laserbee.. Think 2.2-2.3W is all I have got out of my m140's. And I'm not going to kill my 9mm diodes just yet...

I dont think that is above the threshold...

I believe 30ma is the threshold current. Someone correct me if I am wrong.. but isnt the threshold current the amount of current needed to make it lase?

The diode start lasing at 24mA with an output of 2mW. I guess it hits the 5mW at 27mA

29 4,5 7
34 4,6 9
39 4,7 13

Awesome! Thanks Blord.. I have been wondering what to drive a low ma laser with? I baught some of the 685nm 35mw diodes but am unsure what to drive it with. Everything is based on mo power mo power.. and little on driving the little guy's..

Every driver can be set at low powers. You just need the right set resistors.
It is easier to build low power driver, no heatsinking is needed :)

Has anyone tried to make a 5mw pointer out of these? How low can they go and still be stable?
I have a 10mW in a 10440 host, its awesome! I don't have a LPM, but it seems pretty stable, and forget about the duty cycle, you can have this thing on nearly as long as your battery will last.

Thanks to everybody for the information on these awesome diodes... :thanks:

Just finally fired my first one up in a SSCR2 host with copper heatsink and module...



MicroBoost: 250mA's
With O-like 3 element lens - 180mW's
Current draw at full charge - 470mA's

Very happy! :cool:

Nice host choice. That is also a good current choice. It is all about the nice beam specs.:)

@ JayRob - another beautiful build. That is such a cut little host... perfect for this diode.

:thanks: :beer:

It was either the SSCR2 or the SS10440, but the latter needs a FlexDrive to fit the tiny pill.

So the SSCR2 got it. It has a shinier polish anyway... :D

Wow, that is a small sexy host. Fits perfectly with the nice 450nm diode.
