Generic 3W Recoil Led Flashlight CREE Q5 - from ebay - Torn down to see how it works.

just remember, you will only be able to upgrade it from zero heat sinking to maybe just a notch over zero heat sinking...

watch Justin prove me wrong though

Wait, heat can't move sideways, it can only go in a straight line out the bottom of the LED? Crap! That ruins EVERYTHING!

:bigsmile:

it can, but its still not much material to transfer heat from an overdriven emitter

feel free to prove me wrong though. love being proven wrong. but theres a reason you dont see these being modded too often I am assuming

Who says there has to be only one strut and that it has to be made of aluminum? ;)

Remember this one?

haha... nope. how did that turn out?

Not to hijack a thread it still works great. Maxflex 1.3A driver and 4xpg’s in series.

… and it’s a pretty cool hood ornament.

I see it and I believe it but still shake my head in wonder.

Love to see the rev’d up redeux …

Each strut will affect the beam to some degree, but that said, I think three struts out of copper would help a lot better than one strut out of cast aluminum (and they could be thinner and still take away more heat). Cast aluminum does not transfer heat very well. It would be a challenge to make and to solder for sure, but unless I were to do one with a larger mirror and something like an MT-G2, I don’t think I would do it. The reason that the inside is rough, is to smooth out the beam overall, (I believe), so any replacement copper would also need to be rough to some extent. Probably 120 grit paper would be about right, or even 220 grit. In fact, the copper would probably need to be painted with either chrome or aluminum colored paint, for the thing to work right.

I could see some 0.50" 0r 0.75" copper sheet cut like the stock support is (three of them) and a center piece of solid copper. I would also think that the distance from the post to the mirror will have to be tested for any other led, since they will all probably focus at different distances. I would like to see it where it wasn't focused to square die on the mirror, just to see the results. Might not be worth it. The 50mm and 75mm mirrors I have found, that are in the budget range, focus at about 500mm or 1000mm, versus the one in the light that focuses at about 100mm.

I hope you guys go ahead and work all the bugs out on one, so I don't have to.Wink

These recoil throwers scream “HEAT PIPE”!!!

But you have the concave reflector

. It seems to me that the focal length of the reflector is independent of the die size so each emitter used would just produce a different sized image but focus the same distance from the reflector. Correct? Incorrect? If so then there’s no reason you couldn’t put an N219 in there on your 3 fin supports slotted into the housing.

I work the bugs out with a good spray of Mortein. Sorry I cant be of more help.

Yeah, and no thanks for the guy who started the thread in the first place, lol.
Good to see I’ve kickstarted a bit of a recoil movement though. Maybe I’ll mod mine with a more powerful driver…. 0.4A isn’t too great.

I don’t know. I just figured it would, but that does not mean it would.

I bought this for my son, from DX about 3 years ago. He wanted a ‘thrower’ and this was the most affordable.
Since then he acquired a Dereelight aspheric and this light has been relegated to some far-off corner of his room :stuck_out_tongue:

Thank you for the tear-down, O-L! I had never seen this kind of design before. I think I have to get one now.

This design is new to me. How many KCD can this thing get to?

The Recoil Light’s squarish beam looks very bright. I like the design too.
