Do you have a mill?

I have this Chinese mill drill

The threads look real good LTP.

I was happy enough for my first attempt
V threads are better.

Realized I needed a bezel

skimmed bit of flat

turned it to suit

trimmed the back of the head a little

its a sizable thing

now to get time to finish and source some orings

Nice re-purpose of a cylinder shaft LTP. :+1:

Its coming along nicely LTP. Not hard to tell your new camera pictures. :+1:

Sorry to dissapoint. But i just wiped the crud off the phone lens

:person_facepalming:

Its finally done.

Beside Acebeam K40m


Opened up

Recap 4 x 21700 Xhp70.2+L6 smooth reflector+ Lexel ta Driver with Bistro

Thanks 4 watching

:+1: Very nice build! That will take some time to warm up, even with a 70.2. Is the led on a 20mm board? Any idea what current it draws?
The beam looks impressive!

20mm board from kd. no idea of current I was hoping 7 or 8 amps,
I don’t think heat should be a problem,

Nice :+1:

Nice :+1: :+1:

Must be a good light for camping. Solid chunk of ali with good battery life. Nice.

That looks amazing. :beer:

ok charged the batts 11.3 amps when fresh,so should be good for roughly 7000 lumens may try some heavier wires to the led and see if I gain any thing

I have all ways wanted to do a lightbar, so thought I would knock up a prototype using

xhp50.2 12v 5000k

C8 reflectors

Lexan lens

3amp drivers was going to run 2 x 3a but dropped back to only 1. from Russia …

roughing out the alloy

not quite enough hardware for all the holes,

radiusing the corners

pocket for driver

assembled light

cheap ebay heatsink for the driver on back

not dark yet

relatively happy with spread / light output

nearly 3a with the car running 14v
so guessing 5000 odd lumens .

wondering if I should run the leds at this level or at 3a each,

now to make one with 10 reflectors that may take a while

You could run 3 amps each if it was cooling satisfactorily. Looks good by the way. Have your flat here still. Not sure how your going to get it.
Cheap as well. Will only cost you two of these lights. :beer:

Hellzyeah! That looks like a sweet build. Did you protect the driver from auto voltage spikes somehow?

The beam looks good.

How did you get the neat arc shape with the mill?
