Drop-in Surefire M3 DDF

Hi I'm Daniel, I am a user of CPFITALIAFORUM.IT, and I wanted to share with you some photos of this Drop-in made ​​by me with a normal lathe and lots of patience.

Hope you like it.


First working prototype:

















Final prototype:












Difference from Veleno:







-Body in aluminum alloy 6082 thermal conductivity 172 W / m ° C


-Driver:
* Step-Down (Buck) driver
* Voltage: 3.3-10V
* Output current and ways:
High (1A) - Medium (300mA) - Low (50mA) - Strobe - SOS
* PWM frequency: 5000Hz
* Constant current circuit
* Memory function
* Gold-plated contacts
* Low Voltage Protection: The light flashes slowly at 3.3 V and 6.2 V


-LED XP-G or XP-E (A customer's choice).


-Led Thermal paste, Arctic Silver Alumina Adhesive:
* Use layers composed of aluminum oxide and boron nitride.
* Pure electrical insulator, not capacitive.


-Apex of the Drop-in burnished for a flawless beam.


-Insulated copper wires.


Spring-negative and positive gold-plated.


-Inside of the drop-in filled with thermical paste to improve thermal conductivity..




I hope nothing is wasted ...


Sorry for my bad english, the dialogue is translated with google.

Looks good...my M3 could use a couple of these modules :thumbup: keep us posted

Thanks to everyone for the compliments , maybe I'll put them on sale in the U.S. market , I see in what to do. I keep you updated!

Beamshot Drop DDF :





In these shot are fed both at 9v.


I forgot to say that the LED is in direct contact with the body of the Drop-in without base to improve the thermal conductivity.
And this drive works at 4,2v, 8.4v and 9v. Max input 10v.

Opinions????

Looks very nice

Great build...
