Very cool design and machine work, enjoying the build! :+1: Triple and Quads with the optics are O.K. but I’d rather have triple reflectors in a small package like these! Where did you find these small triple reflectors?
that’s them Missed…
beamshot not quite dark
around 65m to shed. Looks like some debris on the phone lens.
I guess around 2k lumens for 3 xpg3 at 6a , doesn’t take long to warm up.
happy with the beam pattern…
Nice finish on this one ltp. You have stacking them chips down to a fine art. I’ll have to drop in and have a lesson.
Just a short word on the driver
don’t no if its the 8 extra chips but on medium mode its a full on mosquito (set on 3mode with memory)
is it firmware hardware or extra chips ?
so this Is my first light with audible pwm
It happens. I’m no expert but some do and some dont. A crook earth also wont help. If I get a chance I’ll drop in and you can give me a lesson on soldering chips.
Just a little update
2 more heads built slightly heavier diameter up to 41.5mm from 40mm
head is now 8mm longer shelf now 10mm thick and another 3mm of thread
in the driver battery tube area
one is for a 17mm driver the other for a 20mm.
until next time.
Nearly finished? The wall thickness looks pretty thin in places. Must have had the sweat glands working overtime.
bit to do yet and i’m adding a quad to the mix/
series.so it will be 3x3+ a 4 all jammed into a 42mm dia head.
will have to trim the reflector a tad and perhaps tighten the thread pitch
and then we may see how good the blf drivers from bangood are…
a few hiccups and here we go.
had to trim the 16mm stars
solders a little ratty
slightly bigger than the first one
the blf driver is doing some strange things when trying to take a tailcap reading it flickers and goes back to low instead of the 4th mode
but works fine with the cap fitted,
Sweet builds ltp. Whats the leds? Have you got an anodising setup going?
xpg3 1a,from kd. cheap as chips. about 2 $ each
no the anodized one in the middle is a convoy c8.
we did anodizing at school cant remember how it was done though
I dont remember the anodising but do remember quenching hot steel in oil to blacken it. So why are the two new lights blue?
I polished it and bounced it on the lathe bed :confounded: , could be a reflection as in earlier posts the first one looks silver to me
Nice work Ben :+1: I might get inspired to machine a host from scratch one day :laughing:
Might be the contrast against the orange towel…??
Ok, I'm late to the party, but is it just me or.. that beam shot is amazing. Take a look at that pic again and think bicycling. Maybe I should quit messing with xm-l2's.
Yes please. 
wont run off a dynamo very well. 
but yes triples ect put out a whole lot of light,i will take a pic on med level when next home
as I am sure you wont want to run at 6a for bike riding…
“PP we all want to see a build from you and your machine”
Wow! Super impressive!!
