I was feeling destructive and did for one.
I was going to stick the parts into a mag aaa.
The LED has gone into a Gerber Infinity Ultra (floody, no spot)
If I remember rightly.
The aluminium collar has white gunk in it which I took to be thermal paste of some kind.
The LED is on long stalky leads going up through the collar.
The components are on a small 8mm diam board and are not potted.
The inductor has two windings I'd guess on a 1:3 or 1:4 ratio. Similar to some simple transistor boost circuits I've built.
I sliced the SMJLED leads off at the base of the alu collar then dissected it.
You have to lever the alu collar up and then slice through. Or was it dig out the button and work from the bottom up.
It still worked when I connected it back up. The metal tabs at the side make the contact for the other battery connection. There is a wire soldered into the solder button at the base of the flanged bit.
I potted the circuit in epoxy to avoid damaging it!! Meaning everything is gunked up now.
You don't kill it when you dismantle it but be very careful.
There are some realy fine wires in there which will snap easily.
I can't macro at the moment but will have a look at it if no one esle does.
Now I've done it I wish I hadn't.
Cheers.
