    Default Newbie just finished building M@G Cree (5 cree)

    After gathering alot of informations from CPF i finally build my own, for first timer like me this turns into an extremely difficult mod but at the end i finally made it. One thing for sure, it was WORTH IT!!!
    this thing is really really bright . Time spent: 5 hours

    LED: Using 5 Cree Q2 driven @1A.
    Reflector : DX 17mm Reflector, dremeled to fit
    Heatsink: Multisink by download
    Power: 14 Sanyo 2700.
    Window: still using plastic window.





    Entire room lights up source only from the MagCree.

    am i officially a flashaholic now?

    Thanks.

    UPDATE:

    A whole setup moved to 3D body + Maxflex Driver and Modified Mag switch to work with Maxflex switch input.

    very nice now get the ucl

    and what reflectors you using ,it looks like it has threads as if pulled from other lights

    Reflector is actually from DealExtreme its 18.5mm in diameter i am in budget and they are cheap, i have to dremel it just to make it fits because i want 5 cree inside...I have several Smooth reflectors and planing to have alternating OP-SMO-OP reflector for better throw. I will dremel the thread later so the reflector will sits even better....

    I have second MagHotwire project running side by side with MagCree project, i ordered UCL and boro lens for both project but still not arrived

    BTW. that avatar looks really cool, 8 Cree??? that must be crazy!! any advice on building one?

    Thanks...

    Thanks all for nice words

    Basically i dont have much money to make this mod "perfect" the first time. I was planning to add proper boost regulator for the next stage. Currently it is just a simple and plain wirewound ceramic resistor, i know this 5W resistor is overkill but this is the only one i can get around the house that matched the required ohm value. When freshly charged all 14 Sanyos and 1 ohm resistor will give exactly 1.2A to LEDs and give ample room when the voltage drops further and i know it will drop fairly quickly as the battery sag to its normal working range this is a problem with resistor. But so far i'm quite satisfied with the performance despite using only a resistor and no noticeable drop in brightness even after 10 minutes of uses(on and off of course). Using it for just 15 second the head feels warm.
    Sorry no driver inside at least at the moment...


    this is how i connect the switch to the head. Again simple and cheap.




    this is my battery pack i know it is ugly. Notice the two plugs, one for charger and one to connect to the Maglite. Since the resistor is budled with the pack i have to make two seperate connector each for different purpose. One before the resistor(charging) and one after the resistor(to maglite). I will buy a smaller size resistor and put the resistor behind the Heatsink or in Mag Head to make thing simple but that is another story..
    I have to cut mag tail spring about 1.5 turn so the tailcap can screw in nicely. The negative cabel from the battery is pressed between tail spring and tailbody to make contact. And the positive is directly soldered to Positive spring at the switch and the cable is running along the battery tube and ended at the rear tube opening.


    battery pack partly inside the tube. The tube is slightly bored otherwise all 4 sanyos across will not fit inside.



    Ok Now Beamshots...
    I only have WF-400 Q2 at the moment it is bright light with good throw to giveyou at least a comparative review as how bright this MagCree is...Camera settings are the same for each place so comparation can be made. White balance was set to Daylight...I have set EV to lower than default to give similar brightness to normal eye.

    First WF-400

    MagCree

    How did you solder the cells end to end like that?
    How do you "aim" the emitters... is it very sensitive to how on-axis they are?

    From my experience, you want the emitters parallel, which is also the easiest angle to accomplish. I did a 7-cree spotlight with p60 dropins and just epoxied the dropins to the spotlight's window. Outside of two feet, the spots spread out and blend into one.

    I Pressed each battery quickly after i remove the solder and before the lead start to harden. i have to apply a blob to each contact, melt them and then joins them while they are hot...

    they are being pressed down hard by the front plastic windows, so they are in allignment automatically and lays flat. DX Reflectors has flat bottom that sits nicely at the emitter's solder point. You have to isolate this otherwise you will get a short...

    @nanotech17: yes it is direct drive. I am surprise by its runtime so far probably because of the nature of low vF of the Cree Q2(measure 3.36v@0.9A)

    @Vbest: Sure

    @sawlight: i live on the other side of this planet.

    @drew2001: it started as Hotwire mod, but turns out into MagLED mods.

    Can anyone advice me whether it is safe to run all the Crees @2A with my setup? i am using Multisink from download and all three(oops! edit:five) emitters are using thermal compound and pressed hard by the windows..it is hot already with current setup but i was thinking of bumping it up a bit....

    Thanks.

    Yep... you've been bitten by the bug.

    Nice mod, Rizky!... and nice indoor pool!... hehe.

    2A for those Cree's? Perhaps someone more experienced will chime in, but that may not be a good idea. The heatsink may not be able to draw heat away fast enough.

    Thing looks pretty darn bright as is, and 2A may be well past diminishing returns.

    Nice. I was thinking of going 5 instead of 4 for my 3C mag as I would only loose 15min runtime. 1 hr vs 1hr 15min isn't that big of a loss for gaining ~200 lm!

    Cool find on the DX reflectors. I have bare emitters (one less thermal interface) and soldering wires directly to the emitters might interfere with the reflector sitting down enough. Are you saying even with stars the reflector touches the wires?

    Cree @ 2amp, not in your setup. Too many emitters, too much heat. I have a project with a cree on a huge CPU heatsink, at 2amp (with a focusable TV projection lens). After 1.5amp you don't gain much more, just heat. But if your heatsink is already hot you likely won't gain anything as the hotter the LED the less light they make.

    Dissipating 40W from that small an area isn't going to go very well.

    Sharper Beamshots if you dont mind.... that Sodium light is annoying i know, wish i had M@g623













    Bimmerboy: yeah it is bright enough i guess i will have to make bigger custom MagHead to pack more emitter inside. No that is not an indoor pool, it is only a plastic net to keep falling leaves from the trees up ahead...

    @LukeA: did not realize that it is 40watt of heat already...

    @IsaacHayes: let me know when your 5 cree mag is ready, my plan was to pack 6 cree's but i could not find smaller reflectors maybe i have to make one
    as with the DX reflectors, yes they sits flat on the emitter shoulder covering the contact pads near the dome(not the pads on the star). If your solder blobs are too big yes it will touch those...keep the solder thin and you are safe.
    Yes you would need to dremel the DX reflector if you were to solder directly to emitter without the star..

    I guess I'll have to order those DX reflectors then! Thanks for the find! I'm running 5,000mah C NiMH. I plan to have a resistor for each LED, all of them parallel to the 3xC cells. Yes no driver but as you know NiMH has a decent flat discharge curve. And the voltage is close to that of the LEDs. Without having five separate buck/boost circuits or more cells and wire in series this is the simplest way to run them with only 3 cells to deal with. My 3C mag was one that was re-plated in HA natural too! I should have +/- 1 hr runtime with 5 emitters, vs 1hr 15mins with 4.

    I was afraid about clearance with the reflectors. I have some thin copper sheet that is flexible (I think I pulled it from an old phone, it's shielding and had a wire soldered to it). I think I will solder that to the top of the emitter pads and run that to a wire so that the amount of clearancing on the reflectors is minimal.

    My heatsink is a PES2 from mod-a-mag that I have machined flat (well I did it by hand but you get the idea). I think I will try the smooth reflectors for max throw.

    You can fit 7 reflectors/leds in a circle with NO wasted space. I think you should go for 7 instead of 6. That way there is no hole in the middle. I *think* 17mm reflectors fit that way... I've seen it done before in stock mag heads.

    EDIT: Those beam shots are great! Really motivates me! I have a tri-luxeon3 (~200 lumens before optics) and it lights up the whole back yard. I can't wait to see what ~1000 lumens looks like. I already have the Q5's, just need the reflectors.

    rizky_p,
    do you think it is safe to run 2x 18650 cell in series to direct drive 5 crees without any resistor?
    anybody would like to chime in?

    Personally i would add 0,22R resistor to each led...
    Edit: ups, didn't see in "series"! I would add resistors if they would be in paralell.

    Driving 5 paralel crees from 2 series 18650 ower resistors would be too mutch losses in them, it would be more than a half...
    You need some driver..
    It would be easier to drive 4 or 6 leds from 2xlions in series, see my mod in progress.
