Courui DO1 Mod. 6 xml.

Hi all,


Here is my contribution to the Courui big head band wagon.     I have to say this host is so perfect for modding the hardest part is figuring out which one to build first.

 

 

   The main idea for this build is to have a light that is a few thousand lumens but is well able to maintain that output for extended periods of time.  

So where to start...?  With a big chunk of metal I'd say.

 

 

 

 

After a little trimming here is a picture of the new heat sink next to the factory "heat sink" that comes with the 6 xml reflector LOL!

 




I am shooting for around 12 amps of power so a set of my 7135 drivers should do the trick.

 

 

 

Heat sink and a sandwich.

 

 

 

 

Add some LED and holes so the reflector can be screwed down.

 

 

 

 

 

I had a lot of resistance problems with this light so I enlisted some 18G teflon wire.     Officially I am going to have to say NOT RECOMMENDED FOR USE IN FLASHLIGHTS!!!!





LOL!!    Seriously if you have any other choice go with that choice....     Even with the over sized pads on my driver this stuff is dangerously stiff.

 

 

A few other standard procedures and we are in business.

 

 

 

 

 

 

And here we have it...]

Now see there wasn't that fun and easy to do boys and girls Smile

 

 

Yeah RIGHT!!


I don't know why but this simple light really kicked my tail.    There were so many places I had to dig out to lower the resistance in this host.    Test re-test check again.   It literally took me like 2 days of work to get this done LOL!      Totally worth it though Smile





Anyway just for kicks I did take a few measurements for the out put.     Please bear in mind this light will not fit in my sphere so in order to get a gauge on it I took my calibration light and held it out at the edge where this light would be sitting and went from there.     That said a grain of salt may be needed.

Turn on.......3328

30 sec.........3320

1 min..........3305

2 min..........3312 <--- Ya it actually went up.   I guess the batteries got warmed up.

3 min..........3305




Thanks for watching Smile

Fantastic build. I have a D01 sitting for a snowy day build this winter but it won’t be anything as ambitious as yours.
Nice job!

I remember a time, when I searched for lights to fit my needs. Now I search for needs to fit my lights.

Very nice! I Like the big chunk of aluminum! I got a D01 under the knife right now too. Just waiting on a chunk of copper to arrive. Great host light, the hard decision is what to put in it!!

Wow, really nice setup! I love it!

Think your lumens measurements are a bit low for ~2A per LED. I would think about 4,200 lumens at about 700 lumens per LED. I just did a mod to an old school UltraFire WF-1300L, listed here, bought back in 2/11: upgraded to 7 XM-L2 U2 1D's on 16mm SinkPAD's mounted on copper discs to elevate the LED's, resistor modded to boost tailcap reading from ~2A to ~3A for 3S cells and got ~3,700 lumens @30 secs in my PVC lightbox. Calculated, it's 1.35A per LED (probably less with driver loss's) and measured ~530 lumens per LED. This WF-1300L really lacks a good heat path to the body with the "floating pill" design. Ran it for 3 mins and the light didn't really get warm (scary...).

Your super pill/heat sink is an ideal type of mod for the WF-1300L. This light has a great heat sink for a body - it's massive, over-engineered like many old generation lights. It has a weird twisty tail setup for mode ON/OFF/modes, but works reliably. Don't think anyone would spend $130 for this antique today, but if you had one, or could get one cheap, I'd recommend it for you to do a similar mod. You could use only 6 LED's in 2P3S for a zener mod driver for running with the 3S cells.

Where did you get the 6 XML reflector?

Very nice VOB. A real home grown effort all round. I had to look twice at the heatsink with the leds in it as I could not see any stars. Whats next on the list?

Tom, I'm glad you here.   You could actually say "I couldn't have done this without ya".    Something I had not yet mentioned is that I used your stellar momentary UI ( your version of the STAR).     Not sure if you saw it in that thread but I mentioned your being a hero.    Probly the best mom ui I have ever used bar none.


To answer your other quesiton about the output.   I would think your right 4200 would be about my guess too for 12A light, one reason I think I got a bit lower number is I didnt actually get the full 12A I was going for.   I ended up about 4 chips short of that goal once all the wiring etc was done so I'm getting a consistent 10.5.       I'm ok with it though.   It seems to have given the light a very stable output.    Even after I ran it 20 min or so to let the over voltage of the cells burn off, I put it back in the sphere (once it had cooled) and it held very very near the same.

The 6 led reflector was actually an XRE not XML ( my bad)   I could swear I got mine from DX for like $6-7, but I cant seem to find the empty module there right now.    KD has them for $11 though.

Thanks.   

Next?    That is a good question.   I am definitely going to order another hand full of these, but at the moment I have already used the ones I had.

Wow, glad to hear you like the e-switch UI! Smile. I thought it would be a bigger hit, tell you the truth. It's really got me slanted to side switch lights now. Shame the X6, JAX Z1, Convoy's (accept L4) aren't there yet - great quality, but tail power switch's I feel now are sub par and somewhat outdated.

The Courui, Yezl Y3, Convoy L4, SupFire L5, FandyFire/SS K2, even the Warsun X60 are all at the top of my list now because of the UI and conveinence of the side switch. Got a bunch of small side switch lights too but always in the hunt for something better in quality and mod friendly.

Great mod!

Love the photo of the head standing up with the 18ga wire.Cool

That Teflon coated stuff is tuff, but it's more about the fact that the wire strands are much bigger. About 19 strands versus about 100? strands in the Silicon coated wire and the Teflon stuff is silver plated as well. If you need to bend them, it's best to work them a little. If I have to bend them, I try to coil them first and then stretch the coil out to solder the ends and then they compress easier. I still think the 19 strand wire takes more amperage than the fine strand stuff, but that's probably just me.

Thanks everyone for your compliments, and your input Smile



Tom,  I'm with ya on the mom switch.   For super high current mods I think its the way to go.   If for no other reason than you totally bypass the switch with all that current.    No more trying to cram a bowling ball size switch into a tiny little hole.

I think part of  the reason your UI hasn't gained the traction that it well should is just because people have either not heard of it or they dont yet grasp what it is yet.

Even after programming a driver with it, it took me a little bit of playing with it in hand to full appreciate how intuitive it is.     Everything about it gives you INSTANT access to exactly what you want.   High NOW,  Low NOW, Stobe NOW, OFF NOW,  WITHOUT having to cycle through ANY mode  you DONT want to get there.

I had to do a lot of digging through the STAR thread to find it.   20+ comments a day bury it further and further in.

I was looking specifically for a mom UI for this exact light when I found it.      

I may be way off with this but perhaps a short video showcasing its simplicity and effectiveness would enable more people to take advantage of its awesomeness?

Hhmm, good idea. Also a dedicated thread I suppose.

That instant access to the most important things is what I wanted - that was the main purpose for sure...
