This is my direct drive PT54 flashlight which I finally got to building after having the led sit around for quite a while and I have to say, its a BEAST!
Although the PT 54 is pretty old now compared to the quickly advancing Cree LED's it still pumps out the lumens, only problem is heat... the only thing that excels the light output of this is its heat output. If I were to leave this on for 2 mins, the whole light would be at boiling point :eg:.
Here's a short overview of the build:
The stock pill on the C6 would never fit the PT 54 so some modifications had to be done, I filed down the pill until it was completely flat and then used a sanded copper coin in attempt to get some better thermal characteristics and rise the led to the reflector, silicon thermal glue was used to bond the coin to the led and the coin to the pill. I also had to cut some grooves in the side of the pill to allow the wires to come out.
Since the led is case positive, instead of trying to work around it by insulating it from the host I used it to my advantage by making making it a case positive build, all I needed was a neo magnet I got from a CD drive to make the neg of the battery touch the positive input on the Blank battery board (its just a broken driver which seems to let current go right through)
Yeah its a trustfire, yeah its from DX. BUT they are close to their claimed capacity and I have a lucky cell that can put out 5a in this light with no explosions.
A look into the eye of the beast
You may call that wire too small, I call it current limiting
And now some pics of it operating, its all I ever look at on build threads anyway....
The other light in this^ pic is an x8 from DX which draws 3a from the tailcap and has and xml t6 emitter, which would put out about 800 to 900 lumens, it also has a massive reflector so the light is more concentrated compared to the red.
If I had to guess the light output I would say around 700 lumens, that's just me though, and I may be more sensitive to red light than others (at least I think so).
Overall cost is about 30 bucks, wouldn't be possible without DTR, thanks for selling cool stuff :bowdown:
