Ultrafire WF-602A1 mod question

[cmaylodm]

I recently ordered an SSC P4 W0 bin emitter and a FLuPIC v2.2 to put in my Ultrafire WF-602A1, and I have a few questions I'd like to get out of the way before I start soldering things together. First, has anyone had luck removing the stock driver board from the pill? I tried grabbing it from the sides with some needle nose pliers, but no luck. Secondly, will the SSC P4 be able to handle the 1.2A maximum supplied by the FLuPIC? I don't plan on using this mode much, if at all, but I'd like to know if it will instaflash the emitter (if that is even possible).

Finally, I'd like to add that the WF-602A1 sold by Dealextreme is one hell of a cheap light, and is worth every cent. A few modifications were needed to get the light working perfectly, but for a $15 light I can't complain. Almost as bright as my roommates HDS, and on par with his Kroma! :rock:

I think you need to unsolder the sides of the driver board. Looks like solder is holding the board in place where it screws into the head. I have the same light and was thinking about doing the same mods. Post some pictures if you can.

Well, the only thing I can tell you is that I am positive that the SSC P4 can handle 1.2A bursts....so you will not instanly cook the LED. However; I am unsure as to how long, if ran in regulation, that the LED could sustain that amount of current.

I am getting my information for none other than master builder himself... "Mac". He just finished a sweet build for me using a chopped and customized Mag body, flupic software, SSC P4, UCL lens, etc....

Oh, and tell Zack I said what up

i once modded the WF-602A version, i guess the innards won't be much different.
the board sat pretty tightly in a brass ring (maybe the edges were soldered together, i can't remember) and this brass ring sat pretty tightly in the pill.
it was pretty hard work getting the whol thing apart....i think the first thing i did was boring two little holes in the brass ring from the side (in these two.....grooves...err...holes..)...i think it didn't work but was useful later.
so i filed a slot into the whole pill in order to take away some pressure and finally could pry out the ring/board part.

removing the board from the brass ring was pretty easy once that was done.

you might also try heating the whole pill with a torch.

or - if you're going to throw away the stock board anyway - simply take a drill and bore it out.


i have mine apart at the moment, i'll post a picture when my digicam batteries are recharged.

and yes, the P4 can easily handle 1,2A, given a good heatsinking. so how do you isolate the P4's slug? if you manage to keep heat transfer decent enough, there's enough thermal mass for the burst mode. i had mine running for half an hour with a LuxIII and the temperature was still moderate.
one of my 14500s didn't like that discharge rate too much, though.

I don't plan on using the 1.2A burst mode for anything longer than a few seconds, as I consider it more of a show-off feature in a single AA light than anything else. I figure the highest user-settable brightness mode will be plenty enough for a high in this size of a light, and the heatsinking appears to be adequate. I have some Arctic Alumina epoxy to help with the heat transfer and electrical isolation, which won't be as nice as some Arctic Silver 5, but a lot better than nail polish or whatever else people are using.

Now I just have to wait for the FLuPIC and emitter to arrive (W0 bin, w00t!)

That is gonna be a great little light with a lot of punch behind it when you are all said and done! I think you will enjoy the flupic software the most about this light, because the adjustable multi-levels rock :rock: Well, that and the near perfect white tint from the WO bin

I wanna see some pics and beamshots when you are done! If it turns out as good as I think it's going too, I may have to have you mod one out for me too! :naughty:
