Thanks for the comments guys. Beer
I’m just a little excited as the light is at this point finished. I’m posting up some of the last build shots and later I’ll get the glamour pictures up.

The driver is powered up to set the parameters and power output before assembling into the torch. The driver is a Taskled H6Flex.

On assembling the light I was having trouble running the fan wires in the groove with the led power wires which by the way are 18 AWG, so decided the easy way out was to run them in there own groove.

The power wires for the leds coming out of the head along with the fan wiring. I would have liked to power the fan from the driver but this was not possible due to room restraints and assembly issues.
In the front two reflector thread holes in the top plate you can see the channels where the wiring runs to the third led.

The driver has been assembled into the head, switch wired up and the driver board used for the positive power to the driver soldered on.

And finally where I seem to always have issues with blowing leds, hit the switch and three Luminus SST-40 leds erupted into a dull glow without blowing up. Yahoo says I. Smile

Here we go. I’ve waffled on enough throughout this thread so I’ll let the pictures do the talking this time.

The keepers of the light.

And finally a group shot of previous lights inspired by Justin and a few of you here.

Night shots etc to follow at a later date.

Pretty sure you can be considered the best custom flashlight maker in the world. One day, maybe a hundred years from now these lights will be auctioned off at Christie’s Auction for tens of thousands of dollars.

I’m not sure about that but if that is the case you can have all the proceeds. Smile
Your comments are humbling. Blushing

Awesome works there Sir.
The copper inlay part amazed me early on. Love the radius curve and taper at the head @ switch button area. Uniform knurling…
Some skills shown.

Awaiting more pics.

Thank vw pieces. Are you waiting for night shots or something else?

I’m charging batteries at the moment for a shoot out but will have to wait for the weekend for this to happen as its still not dark here when I go to bed.
I need a new spot for long distant beam shots as my last place is now out of bounds.

Do those batteries yell out “Charge!” when they are ready to use? Facepalm

Think Steve might have a fascination with space somewhere in the back of his mind. I posted in the build thread that the one with the wood accents(post 125, last picture, far right) looks like it might be something from the TV show “Lost in Space”.

I wish they did. The bludgers have been taking lessons from the sacked assistants and do this most of the day. Silly

I’ve still got to set the driver up to its final settings. I’ve set the step down for a conservative 50 degrees C. In a room at around 25 degrees C it runs for 12 minutes before step down. This is with the 3 leds running at six amps. The light feels slightly less hotter than this temp so will play with the settings more at a later date.

Like many kids my age at the time Lost In Space was cutting edge TV in all its black and white glory. Smile
I dont know how they put up with that mischievous Mr Smith for so long. Love

On a side note I got onto Google earth and sussed out a new place around the corner for night shots. On scoping the area out 520 meter pictures should be possible. All going well I’ll get there Friday night.

You’ve really outdone yourself this time. I don’t even know what to say. It’s beautiful!

Also, it’s powered by Spartans. That brings back memories…

Thanks TK. When I saw the Sparton wrappers at FT I knew straight away they were the ones I was after. Smile
I wasn’t sure how they would line up in the battery tube slots as they were roughly marked out with a texta in the mill and machined to nothing in particular. Facepalm

I was carrying out some extreme testing last night with the leds at 6.6 amps each and the temp cutoff set at 80 degrees C.
At the 22 minute mark the light just switched off. Head temp was around 60 degrees C.
It appears theres a short somewhere. I’m thinking that maybe a fan wire melted through as I have no idea what temp rating it was.
Needless to say a strip down is required. Hopefully the driver and leds are ok.
Up to this point I was really happy with the way the torch was performing as output had only sagged around 10%.
Lumens output is right up there with the Q8.

Other than that sounds great Smile

I’ve lost count of the number of times I’ve had my custom-made lights break during use (or while testing their limits). Usually it’s the ones I use for development, because the wires are stressed and moved around frequently, so the contacts break. A couple days ago a contact pad broke off one of my dev drivers, so I have to build a whole new one. Had to repair another one earlier today. I’m thinking I’ll design a new PCB instead, with greater physical durability.

I hope yours will be an easy fix.

The torch is back up and running after a strip down of the naked light to find the problem. My assumption above about the wiring on the fan melting causing a short was not the problem unfortunately. The wires were upgraded though when I reassembled it with 24 AWG silicone wires.
The problem was me. The driver pocket was .25mm not deep enough for the driver to sit flush with the top with the adhesive backing on the driver. When I tightened the earth screw all was ok until the torch was very hot. The glue gave way on the opposite side of the earth screw as the driver was acting as if it had a lever on one side.
This allowed the driver to overheat with dire consequences.
Luckily I had one spare driver.

Thursday after work I took a daytime picture of my chosen 500 meter range for the night shots. Rocked up there last night and you wouldn’t read about it, the building 500 meters away was lit up like daytime with security lights.
After exhaustive searching with a very patient wife by my side another location was found, not the 500 meters I was after but 230 meters, to the trees. The white box is 75 meters away while the fence is 93 meters away.

Fistly the prototype Q8 I built up. This has about 10% less output than the production version.

Monster Torch. DX large reflector with MTG2 at 5 amps.

C83. Three x C8 reflectors with XML2 leds at 6 amps each.

Old Lumens Tribute Torch. LUM 5-90 reflector and XHP70 led running somewhere above 10 amps.

And finally the Naked Torch.

This is the run time I was carrying out at the time of the blow up. The bottom line numbers multiplied x 2 will give you minutes and the line is the output.
Head temp at 22 minutes was approximately 60 degrees. Each led was running at 6.5 amps.
