This isn't a build yet, but I did a quickie test of the LD-36 driver from LCK In the COURUI.
All all I wanted to do was see if it fit and worked. I just hooked it to the stock emitter and stuck it in. I had to replace the wires with longer ones for reach.
It seems to fit. It's slightly raised on one edge, I'm not sure if it's the little press fit protrusions that need to be sanded, or if it's sitting on a chip. I'll inspect it closer when I start the build.
Anyway, it's tight and flush enough as is. I wouldn't worry about leaving it this way. I wasn't getting ground connectivity with the body so I did fast fix.
I stuck a copper head pin through a connecting hole on the ground ring and curled it around the ledge where the battery tube abuts.
Anyway, it works. I tested it with leads hooked up to two cells in series. Momentary switch works fine. Three modes, I didn't try the ramping as my hands were full and I didn't read the instructions.
Now that it's been tested and proven, I guess I'll have to figure out how to convert the cells to series.
Does anyone know the rating of the switch in this torch? I want to mod it to use 2 drivers in parallel but is it ok to put the power of 3x18650 through this switch before the drivers?
the switch in the head is only electronic momentary switch -not for cutting power to the driver!
it can handle some mA only
ouchy drilled the tailcap and added a power switch there
I remove the R200 resistor and put a solder blob across it, getting about 4.7A on high. Another member gets 5.8A by doing the same thing though. :cowboy_hat_face:
Replaced the r200 with a small blob of solder and now i get nothing. I tried replacing it with a small wire and also replaced the r200 and still doesnt work. Dont understand why was an easy soldering job any ideas?
Edit: its working now i tried again with a blob of solder but dont understand why it didnt at first :s
and when i say working it only works when the emitter shelf isnt screwed in? When the shelf is screwed in it is permenently turned on
Sounds like shorting in somewhere. I’ve had the permanently on problem too and it takes quite some time to diagnose.
Your problem occurs with/without putting on the reflector? Did you notice any smoke came out from the LED when it is on? Other than that you can also check the connectivity of your LED using a DMM. You need to check the +ve pad with the -ve pad, +ve pad with the LED star base, and -ve pad with the LED star base.
EDIT: Oh crap, my LED still on when it was switched off. I realized that it is not because of the LED but something to do with the driver. I have spent too many hours diagnosing this issue but still cannot figure out a solution, think I am going to create a new thread asking for help. :_(
I never found out what was shorting but it managed to fix itself and then me being and moron threaded the reflector back on not checking the centering ring and shorted across the reflector and blew the blard but im not too fussed got other plans for it now
Just finished filing the reflector base of my T08. What did you do to remove the dust particles from the inside of the reflector? It seem that blowing as hard as I can ain’t enough.
Filing the base of the T08 reflector did increase the lux by 8%. I’m only getting 151kcd before. After the filing, its 163kcd. I would just leave the micro dust particle as it is for now. I can’t risk another damaged reflector.
Try to wash it with water+some liquid soap (do not touch it with anything,just let the water flow).After that rinse it with pure alcohol and dry it with hairdryer(dry it from outside!).Oven would be probably better(no moving air-less dust).I tried this few days ago.I had one reflector with a lot of dust,and even some grease-like spots.It worked much better than I thought,reflector is now almost like new.
Just finished washing the reflector with warm water and hand soap solution. The result is a good as new reflector after drying it in front of the fan. Thanx for the tip led4power!
As led4power said, wash it with water will do. I just bought a ball blower like this . Not sure if it is strong enough to blow away the dust and particles on the reflector, never tried yet.
…but since I have washed it quite many times already my T08 reflector is damaged and scratches are everywhere now, perhaps it doesn’t do 190~200kcd anymore. :bigsmile:
if you have a soldering iron of course…
