Guidesman Alu heatsinks - $18 each

Hey guys,

so there is this host which people say it's like original Guidesman, with logo and all:

Red:
eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices

Gray:
http://www.ebay.com/itm/14LED-Flash...lashlights&hash=item3cb99bb8b7#ht_2412wt_1163

So here it is!




The heatsink itself looks like this:




There is a set screw to hold your Aixiz or other laser module in the tinner part, obviously.

The heatsink's lenght is enough to support against the body even if you do not use the board that comes with the light (one containing all the LEDs, you can get rid of them and use it as contact board with it's long spring), but you can also use the board if you want.

There is enough room behind the Aixiz for a variety of drivers which you can attach to the diode directly (like Flex or MicroBoost or any DIY driver).

It is reccomendable that you give a little sandpaper to the edge of the body pressing against the heatsink here:

...for better electrical contact.

That's it folks, direct pressfit version possibly on the way, maybe even have a socket for 17mm driver boards for DX drivers in it, but more on that later.

Heatsinks are $18 a piece, free shipping worldwide - as always.

Enjoy

P.S. Any feedback is welcome!

EDIT - More info about using the PCB as contact board.




That's the board with all the LEDs on it. Remove the black spacer ring.

Obviously, get rid of everything, including the spring (for the moment):


Now, you need to cut this trace here, to prevent the battery + connection shorting against the ground (heatsink and host):


Next, use a couple of those long diode pins to form a connection between heatsink and host (if you don't do this, your heatsink will remain electrically insulated from the rest of the host). Leave the pins sticking out on the heatsink side, solder them on the host contact side on the outter most ring on PCB.


Add your stuff and you're done!


Just put everything back together the way you took it apart, pretty straight forward.

Note, if you do not use the PCB, heatsink is long enough to make the electrical connection to the host itself, but you need to desolder the long spring from the PCB and add it to your driver to form a connection to the switch.

Nice! More guidesman hosts

If not crazy about RED, they have this too:

14LED Flashlight ,Camping Lamp, Bicycle Bike Light | eBay

Link I provided has both red and uhh, other color option, not sure if that's gray or black, but in any case it's not strictly red.

*Looks at link rhd provided* Ah, same seller, same price, just different picture order of the product, might help avoid confusion, thanks! Will add to OP.

That black plastic spacer can be easily removed, it's roughly 20mm thick so you can get a little more room in there.
These are slightly larger in the head than the original Guidesmans only by 1 or 2mm tho and slightly longer by 3 or 4 mm too

I take it my stuff's ready now

Yup, just one question -

Do you want your tailcap modified so the host can take 18650 battery, or are you OK with 3x AAA configuration?

Your stuff will ship on Monday regardless.

The 3aaa config is fine with me

Great!

Just shoot me a PM with your address in it.

Well, My Host and 2 heatsinks arrived today, and a Job well done :beer::beer:
will try and do something with them tonight

Post pictures!

I'm glad you are satisfied.

:beer: on me next time I'm in UK.

They can also pop off that top plastic ring and they will find a spacer sitting behind the switch. This spacer can have the walls hollowed out and fit just about any driver.

I just took mine out and wrapped it in a little electrical tape, alternatively Euda if you can be bothered, you could make a heatsink for the driver, there is plenty of room !!!

Anyhew, here's a link to a mini review I've just done

Thank Moh, I didn't fiddle around with the switch because host is to be shipped to Kookapeli, but when I get my own I'll see where can I put the drivers.

I will also be adding the 17mm pocket for the driver boards if you happen to have DX drivers to use with the build.

Can you pick your color or is it random with this seller? I don't see explicit mention of a choice.
Where Guidesman always this inexpensive? How is the threads & overall quality?

Threads are pretty bad actually, squeaky, though everything else appears solid.

You just make a note to a seller in your Paypal transfer or send an email seperately, as I have.

just put some wd40 on the threads and they're fine no more squeeks
