Re: Need new light för my Green Force .. but cant find ! HELP
Fredrik, where are you? I.e, where is best for you to buy things? USA, Europe?
Yes, driver at that power needs to be heatsinked it will get hot.
Is your optics like this?
http://www.luxeonstar.com/khatod-13-degree-40mm-7-led-40mm-round-optic
It looks like your current board was sitting on upper edge in head leaving lot of space below
So, I assume you have just one level, is that right?
How much light you want vs how long runtime you want?
What temperature of light you want, you ok with cool white, I prefer something around 5000K
My guess is what you had was somewhere between 2000-3000 lm with runtime about 2.5-3h from that canister

Is that right?
I think you should get new 7-up to match you optics, there is few of them, Luca linked some, these are nice too
http://www.luxeonstar.com/neutral-white-4100K-sinkpad-ii-40mm-7-led-round-led-230lm, then get one level boost driver that will drive them as hard as you require - depending on LEDs 1A-1.5A
Other option would be to use 3 LEDs that can do 3A (XP-L or XM-L) but I think you will have hard time finding them on 40mm board and optics will be taller (too tall to fit). You could drive that wilt buck driver at 3A or so.
7-up

http://www.cutter.com.au/proddetail.php?prod=cut1357 same but cool white - bit more lumens but cool
https://www.led-tech.de/en/LED-Modu...EE-XP-G2-R5-on-round-PCB-LT-2678_242_245.html cool white
https://www.led-tech.de/en/LED-Modu...EE-XP-G2-R4-on-round-PCB-LT-2680_242_245.html ~4000K
driver
http://www.taskled.com/hboost.shtml kind of big at 1.3" but from picture it should fit, can set current up to 3A by on board pot, after that simple on/off - VERY GOOD quality and support, expensive
https://pcb-components.de/led-aufwa...d-senser-xtreme-200-2050ma-6v-30v-detail.html smaller but taller, order current you want, probably 1.5A for XP-G2, no personal experience with that one
Cut round metal board to fit bottom (see picture), I would drill 2-3 holes thru it into head body, shallow, just 2-3mm into head (assuming there is enough metal), use thermal compound between it and body and crew it there.
If no holes then use sticky thermal pad, don't use epoxy wit may crack eventually and get loose
Drill hole in it for wires from driver to connectors below.
Attach driver to this board with thermal pad, some crews, connect wires to head and to LED board.
Put LED board in place, lens, close the head. Done!
P.S., if you buy driver from taskLed it comes with very good thermal pad, you may ask George when ordering pretty sure he will send you another piece for few cents so you can attach this driver metal board to head
