DIY Driver swap Guide [ P60 as an example ]

Red to + , which is the centre spring ...

Neg is the pill body ...

Before soldering the driver in place .. Just put the red to centre spring , and neg to the outer edge of driver

Important Update :

Seems the driver actually behaves a little different [ its dark out so went and played a little ]

What ever mode you stop at : When you go to change mode it starts on Low ...

So if you stop on low , and go to change modes , its starts or goes to low , and then you continue to change modes till you get what you want ...

What ever you stop on [ even low ] when you go to change modes , it goes to low ...

So it looks like it will always start from low [ stock ]

Thank you for taking the time and trouble to write this article. It's a little advanced for me as yet, but the pictures really help. Better than a lot of text books.

I highly recommend a solder sucker or solder removal wick for when you are removing the original driver. Either of these can be purchased cheaply from DX. Having these tools will really help if you are going to be doing a lot of soldering.

Do you have a link?

Old4570,

Thank you so much for posting this, I haven't done anything like this with flashlights yet but have been thinking about getting into it, this helps greatly and it seems straightforward.

Is there any chance you, or someone else could post or link me to a similar tutorial for swapping an emitter???

Thanks again, I have bookmarked this.

Thanks for the write up.

I feel like I should take something apart at least to look at it..............

The next part I have to figure out is what to buy for a replacement.

Ummm... how about:

The solder removing wick can be purchased in multiple sizes...

I think you would just figure out what you want out of the light, I.E. modes, current, etc and find a driver to suit your requirements.

Are most all drivers the same size or is that another thing you have to look at when purchasing one?

Bookmarked, thanks!

Flux is also useful both for soldering and desoldering.

You should be able to pick up the solder removal wick at Radio Shack or any local electronics shop

You would want to make sure that the driver you need is the right diameter. 17mm is a very common size and is the sized used in the P60 dropins, but some drivers are larger and some are smaller.

Have you tried these. I managed to reduce one to one mode. I am not too good with soldering small pieces.

If I’m not mistaken the one used here can be made to do a few different modes ie 6 ways ,now how yobdo that I’m not sure ?
When my drivers arrive I will post pics here as well if u don’t mind old?

Another way to remove the old driver is to cut away the solder blob with a sharp hobby knife (mind your thumb) and also cutting vertical along the edge of the driver. This is normally sufficient for prying the driver out at its edge with the knife (again mind the fingers).

I have found that this can snap the blades on hobby knives, so now I have an old small, precision flat blade screwdriver that I use to pry out drivers.

No Problem

KD gives a description of how to mod modes - ill see if I can snap a picture as time permits ..

I use a dremel with a sanding tip to remove solder off the driver and pill I find it easier and quicker.

I think I'm going to try this method. I just tried to desolder my driver and could not get the solder to flow at all. I have no idea what they used to solder this damn thing but I was getting worried that I was gonna fry the board with the heat I had the iron on it so long. All I could do was push the solder around a little bit. I'll just cut it out now.

I use an xacto knife or a razor and cut around the edge of the driver through the solder. I have taken many drivers off this way.
