My first mod finished: M@G 6D 5W Luxeon dd

My m@g 6d is finaly ready. here's some pics.

Emitter on hotlips installed:


This is the powerpuck,I made it fit, but I took it out and made it direct drive:


This is a beamshot with a worn reflector (very bad one)


2 pictures of the head (with UCL fitted):

I will post some beamshots later (It's 16:54 over here)

Good mod Aze. /ubbthreads/images/graemlins/thumbsup.gif Good to see someone with guts /ubbthreads/images/graemlins/grin.gif (/ubbthreads/images/graemlins/thinking.gif /ubbthreads/images/graemlins/icon15.gif) to cut down a Powerpuck to fit an OAD body. This light will give you oooddles of runtime. 6Ds !!! OOOODDLES.

hmz, was to drunk to make pics last night /ubbthreads/images/graemlins/grin.gif
Maybe tonight /ubbthreads/images/graemlins/smile.gif

made some new pics:

new original m@g reflector installed:

how many d-cells is the max for a 5 watter?

Is doesn't seem to get very hot with 6 d-cells?

The Powerpuck limits the output to 750mA (or close to that) so it will not get very hot. For example, some 5w Direct Drive lights (say 9v Lithiums) starts at ~1.8A AND IT DOES GET HOT. So... the more amps, the hotter they get.

How many D-cells? Well, what is the max input rated by the Powerpuck? There is no point putting in more cells as the output is regulated.

I already took the powerpuck out and made it direct-drive. It runs on 6*1.2V 1500 mah D-cells (recharchable).
If only I could measure the amps, but I don't have the equipment for it.

Will my luxeon survive an extra battery? (7 x 1.2v total)

Azz, congratulations on your new mod.

You are breaking new ground here using "D" rechargeables, since despite the voltage rating (1.2V) the inherently low internal resistance of the D's will allow a huge current spike to surge through the Luxeon. You may be saying bye-bye to your 5W (what bin is it -- specifically the Vf?) sooner than desired.

At least leave the batteries out for a day after charging to take some of the edge off. Just my humble suggestion, won't Even address the 7th battery question...but I bet this sucker is Brrrrright!

I don't now the bin, I got it from ledsupply.com.
From now on I'll follow your suggestion to leave the batteries out for a day. (first time I'd put them right in after charging, all I can say that it was super bright when I lit it.

Next step is to mod my reflector to get a smoother beam.
Is there such thing as chrome-paint I can use to fix a reflector which is worn?

I'd either get an Acrylite lens from Otokoyama or one of his speckled aluminum Carley reflectors. The Acrylite lens over your newer Mag reflector will clean up the beam beautifully at the expense of a few lux, but your light is very bright to begin with so you will not notice unless you have a light meter handy.

Azecos... Nice mod!
I would not even think of going to 7 cells.
I lost two LS (popped) with my first15 Watts of TRI (Ion) Flux The vf on the LS's were too low and the current\internal resistance of 9000Mah D-cells was just to much. I then replaced all three LS's with VWAV's.. this solved the problem.. I was also running three in parallel providing more protection than running a single LS.
Be careful, it will pop if pushed too hard. You could not be in better hands with that hotlips heatsink though... they are awesome.
