1405 gone M4D

Flashlight Modding and DIY Parts

Hey!

i had time to play a bit with my (well known) uniquefire 1405…

the “flood” position with the head completely backwards

.

the “beam” position with the head (nearly ;)) all way out

.

looking that light into the eye reveals that there is something not stock :wink:


.

i used plastidip to give the light a black eye to get rid of all most of that standard ringieness…


.

the educated reader have spotted another modification i am sure …
the Stock XM-L2 on Aluminium was replaced by a (gasoline) dedomed XP-G2 - mounted on a noctigon Copper DTP MCPCB

.

some UV-shots:


.

to drive that LED harder i added a R100 resistor on top of the original R120 sense resistor - which pushed the Amperes (measured at the tailcap) to 2,3A

note: a second R100 on top blowed a LED instantly because the driver does not like to be overdriven too hard!
.
i also soldered thicker wires to the LED and did a positive spring bypass (which had no measureable effect - due to the 2S configuration i think)

.

due to the thicker noctigon i could not focus - a cheap solution came in my mind:


now it is possible to focus far away…
.

beamshots…

ISO800 / 1sec

ISO200 / 1sec

a black hole? (ceiling lights are ON !)

.

problems that only could be solved buying a new lens due to brocken edges and “medium” quality:
(colorfading and funny shape - pictures made in automatic mode to show them better)
pictures made before the blackening!






.
Videos have been shot after the blackening…

numb3rs (as taken - maybe a bit high…):
XM-L2 domed 2,2A
flood 730 Lm 0.25 kLux@3m 2.25 kLux@1m
zoom 420Lm 12.2 kLux@3m 109.8 kLux@1m
XP-G2 dedomed 2,3A
flood 730 Lm 0.26 kLux@3m 2.34 kLux@1m
zoom 430Lm 52 kLux@3m 468 kLux@1m

its not perfect - but cheap :wink:

Nice, very nice, UV shot :smiley: but I am not a fan of plastidip.
What do you like better XP-G2 or XM-L2?

I hope that someone will know how to turn stock driver into 1 mode only because I don’t have any other 2s driver (have some OSH boards but no components to populate them).

plastidip was on the shelf and a black marker did not stay on the pill… :wink:

i like the XP-G2 because white laZer 8)

Great mod yu have there. :slight_smile:

I’m confused with one thing though: As you said by adding an R100 on top of the stock R120 it will blow the LED, but you still somehow go with it and it’s still working fine?

one R100 works
two don’t

i blew the XM-L2 which was in the light…
i always do the driver work before using a new LED

Ah I see what you mean now. In fact when I added an R120 on top of it the driver went bad. Not sure if it is due to the production variation, but this driver certainly isn’t able to handle high current.
