Some beautiful machine work going into this! :slight_smile: looking great so far.

Wow, that reflector is just gorgeous! You da man MRsDNF.

Working or not it is looking great and I’m pretty sure you’ll figure out the shorts.

Thanks guys. It has to be shorting under a reflector somewhere or a MPCB is not as it seems. I'll make an adapter up and trim some more of the backside of the reflectors.

If you can acces the B+ spring with the head assembled but not on the battery tube you might be able to find out which reflector is the problem with a meter. Maybe shave a bit off the solder bumps and insulate with AA.

This is quickly becoming a favorite picture of mine showing the initial life in a flashlight.

I have no idea how you did that, applaud you for the idea and obvious hard work it took to merge those 4 reflectors. The entire light is compact, powerful and creative. Shame Matt build such an awesome sceptor, you had a chance before he did that one. :stuck_out_tongue:

Y’all are insane with what you can come up with, maybe some day I’ll put 2 and 2 together and come up with something half as impressive. Nice work!

Hip, hip, hooray! I’d ’ve swung the hammer and then cried. Still cursing over hot copper myself.

Edit- that really is a sweet image of evenly focused LEDs.

You mean you're not finished yet? ;)

That looks great, very nice work!

Thanks guys. PM update with night shots post 5.

Wow, it has become a beauty! And I really like the beam profile, I'm glad you sticked to Torch leds :-) How many did you end up spending on this build?

Nice beam - really lights the whole area up. Job well done!

Thanks guys. I'm not sure what the build cost all up. The reflectors and leds are cheap, the driver around $10.00, AR lens was a couple of dollars, battery holder from a shocker l used the reflector from and the aluminium was from an old hydraulic cylinder. If I had got the light working the first time it would have cost around $25.00 in parts.

Edit. Not including batteries.

Awesome light!

Pretty tight beam given the quad setup. Useable light out there and right here.

That really turned out nice.

Things I like best.

1. The way that you were able to leave that little post in the center of the reflectors to make it all come together so seamlessly.

2. Those super thin fins. I need to get some smaller blades because that really adds some character.

3. The mill work on the tail and body ties it together well.



Thanks for sharing.

Very nice output! I like that, a lot!

The Quad X6 I sent you was my first aluminum sink hand made for that host. Pretty sure it’s got XP-G2 S2 2B emitters with a 10507 optic. Should be in the 2000 lumen area, I forget that part but will see if I can dig up notes on it just because.

I bet you put this light to good use, with such a nice white beam and the coverage it offers! :wink:

Thanks again guys.

@RBD. With last years comp build light using C8 reflectors opened my mind to the fact that multi reflector lights will give a totally different light pattern in respect to the corona and spill being far greater than that same reflector used singularly. Because of this I was confident that the small reflectors with the XPE-2 leds would behave the same way which it has. Instead of a tiny hotspot and bugger all corona and spill as in the single reflector light this light has quite a large corona and more than a usable amount of spill along with the same amount of throw as a decent C8 and has a lot a lot larger hot spot to boot.

I may still change the driver to RMM's and forgo a slight decrease in output for a far better range of light output between modes. As it is med and high are just to close to the same light output in use.

@ vestureofblood. That little post in the middle is only around 3mm in size. I was a little apprehensive machining the last two reflector holes (machined diagonally) as I thought it would snap off. I machined each hole in about a third depth each side rotating the work piece as each cut was taken. No tears had to be shed.

The fins are 2mm in width. I bought a cheap Carbide parting of tool awhile ago. lt is a lot nicer to use than my Hi Speed steel parting of tool though the senses are still at a high level while doing these things.

@ Dale. I went looking for the PM we had at the time that I thought the details were in but as usual I could not find it. The light with your driver in it is a real winner as the beam shots show. I am pondering using the quad parts you gave me to build the giveaway light. Thanks again.
