solarforce dimensions

I was wondering if anyone could provide me some accurate measurements of the drop-in dimensions. Specifically I need:

1) The ID of the host where the drop in goes in.
2) The ID of the bottom of the brass pill. I need the diameter inside where the driver sits though (smaller than the diameter where the driver sits).

I got 22.4mm for the ID of the host.

Alright thanks, 1) down. Just to double check, this is the inside of the TOP of the host correct? Where the drop-in would go?

I’ve been motivated to make a triple LED drop-in and need to find the right OD copper to buy.

Yes, this is the area where the actual drop in goes. Smile I just measured another one of my hosts and got 22.2mm.

It depends on the model. I once made a piece of copper that was a snug fit in an L2 that would not go into an L2P at all. I’m sure that a heatsink made for an early L2 would not fit a newer L2 or vice-versa.

Cool. Does anyone know the diameter on the side of the pills? I would assume around 16-15mm?

Isn’t it better to buy the host and then machine the things you want for it precisely?
I mean very precisely. All hosts are a bit different. Plus you know the factory tolerances in China Big Smile

Make it a snug fit, that’s what I do with custom parts.

I don’t have the tools to machine things perfectly. I’ll just be taking copper and making it fit with foil wrap etc.

I don’t get it. You don’t have the tools to make parts but want the dimensions? If you’re going to wrap a drop-in to fit then why do you need the dimensions? BTW, Solarforce has looser dimensions than Surefire so anything that will fit a Solarforce will fit a Surefire but not vice-versa.

To answer your second question, it’s 17mm on the driver side and usually a bit over 16mm on the emitter side.

But there is a lip the driver sits on and the inside is less than 17. I wanted an estimate so I could get copper rounds as close to the diameter as possible.

I wanted dimensions so I could get things that are as close as possible, then fill the rest with foil. I don’t have the tools to get something larger and “machine” it to fit.

A 17mm driver will fit nicely. The lip is a little less than 2/10mm.

I usually grind a P60 pill down until it fits into the battery tube (Solarforce battery tubes are very long, shouldnt be a problem) and solder them to the copper heatsink.
