    Thanks that makes even me feel better considering Ive only built one simple mhs saber.I really messed up even though it worked but thanks,I always wondered if most of you were bad at first and got better at saber building,now I know its just practice,practice,practice.

    Default lux mishaps

    somethimes things just dont go your way... ive been working on the 5w mr sound combo off and on for about 2 months, figuring out optimum wiring. this was a colaboration of myself and a few of the senior members of the forums. if you look at my history you'll see im certainly not a noob to saber construction, but once the wiring was all mapped out i was so pshyched to do a test run on the final setup that i forgot to put the resistor in, which resulted in burning out the 5w green lux. total drag!

    once i get over my aggrivation at this terrible oversite on my part i'll be replacing the lux and writing up a tutorial on this subject, since i see all too often questions on how-to run a 5w with mr sound in a simple one switch setup. i will tell those reading that before the lux gave up its magic smoke that it was the most impressive setup i have built to date, electronics installed into a customized mr luke hilt body with a 1.25 blade holder and 9.6v rechargeable pack, still using an mr blade tube for testing, and it was by far the brightest and most even looking blade i have done. we all know the mr tubes pretty much suck for reuse in lux hilts, but this thing looked far better than any setup i currently run with either corbin film or ultra fiber optic style blades...

    ill post up later some comparison pics between this setup and an mr anakin k2 royal blue, both using 5 degree optics.

    Lux Vs are awesome... they just take so much voltage to light up, it's really a bummer.

    Sorry to hear about the fried Lux V. It happens though. I've already fried 2 or 3 K2 emitters, but that was because they "floated" away from the heatsink while testing, lol

    Default 5w lux

    no biggie little brother, with all the other hassles that came out of developing that particular setup having to replace the 5w is a pretty simple matter...

    novastar, since you are getting so many lux in non-star format, i was wondering what you are using to secure the emitter to your heatsink?

    Hi jj... well, let's see--firstly, I only have two K2 emitters "serving duty" in sabers right now. They are not AT ALL pretty in how I secured them to the heatsink. In fact, it can hardly be called that at all!

    I tried numerous things, one of which was to use electrical tape to secure the wires holding down the emitter in place. Not great, but workable. Put the optics over that and make sure you have a tight fit when placing it into position under a blade holder. Secure the holder in place so there is no possible room for the LED to move, and you're good.

    Another was to use Artic Alumina "Adhesive". This is also supposed to reduce heat on the LED, and transfer more to the heatsink--rather than just your standard thermal paste or whatever. Well.. it didn't really stay as "adhesive" at all... despite my following the directions to a "T" and then some! That created my first zonked K2. First one I had ever seen, prototype Corbin got me for BOP I.

    Another method was to use the lumileds/luxeonstar "adhesive" optics that are supposed to sit in place over a heatsink. SURVEY SAAAAAAAAAAys....... .... IIIIIIIIIIEEEENNNNNNNH. Wrong. Not only are they 3 degree, but they really don't work for our purposes with where the wire leads go. Hard to explain.

    CONCLUSION:

    Steer clear of K2 emitters. And I mean the EMITTERS... the stars are fine. In fact, steer clear of ALL emitters. Unless you have some seriously planned out, perfectly "spec-ed out" way to work it.

    The TCSS emitters/sinks/holders are WAAAAAY worth their weight in gold... er... credits... whatever.
