Yeah, I’m aware of what the main problem is but the copper should allow me to run it on high for a longer period than aluminium would given the same amount of surface area. At least that is my understanding.

Correct. Roughly 3.32 times as long as aluminum.

About two years ago I had my first taste of using copper as a heatsink in a flashlight. I modified a 3D Mag to power a SST-90 direct-drive using two interchangeable heatsinks. The same emitter, wires, positive contact, host, and batteries were used to isolate the results to just heatsink performance. The results? While both heatsinks would eventually become heat saturated, the copper heatsink would take longer to do so. That heatsink was 16 ounces of C110 copper.

Back on topic, I got the switch modified, tested, and started to assemble the light. After putting the switch into the body I tested it again and found that the trigger wire was not working. Grrrr! I gave up last night and will fix it today. I’m still trying to figure out how I’m going to power this thing to test it. Scaru, what batteries are you going to use to power this thing?

My plan is 3 18650s, I have already figured out the power and the tailcap do you don't need to worry about that. I already deanodized a tailcap and did a shortened spring for it.

Gosh! PPtk you are on a roll here. Wonderful - but now I feel like a kid who saw dad haul a big giftwrapped box in to the garage and locked the door. I want to know more right now :-)

(Yes I know I am childish and unreasonable - it's a feature of mine)

PCC · 2012-10-14T06:03:26.000Z

I want one! What is it? LOL!

I can tell you right now it will be (too) expensive,
and it has I think 6 tabs for programing

Whoop whoop!!!!!

Really looking forward to this!!

I’ll play…it’s a programmable driver for a triple XP-G/E!

scaru · 2012-10-14T14:10:41.000Z

It definitely is a programmable driver, if you look there is no space for LEDs. Also if it were going to have LEDs on it it would be single sided. And it definitely uses the same programmable chip since it has the same 6 pads to reprogram it.

Piesoup · 2012-10-14T18:32:50.000Z

I'm going for a single LED module that has a standoff to sink it to the housing. Look at the large gold circle on the right hand picture, possibly there to transfer the heat away. XML hopefully!

Or a possible pad for soldering a spring!!!

Piesoup · 2012-10-14T18:49:57.000Z

Yes, could be! But the neg ring round the outside looks a bit thin and isn't continuous.

Still reckon its and XML, 3.4 is printed where I think the led is going to sit.

scaru · 2012-10-14T18:54:13.000Z

If it were to have an LED on it it would need to be 1 sided. 2 sided would make all the heat stay in the board and would kill it.

Piesoup · 2012-10-14T19:03:19.000Z

Definitely.

I am hoping a Ali or copper stand off can be positioned on the gold circle on the underside to draw the heat away. It would have to be v efficient so the chips don't overheat as they won't be able to readily get rid of their heat.

You guys are damn imaginative

Piesoup · 2012-10-15T09:09:07.000Z

Are any of us close?!!!

Define “close”

Piesoup · 2012-10-15T16:06:15.000Z

LED module? Or just a driver?!!!

If that’s still the question, then no, you’re not close
