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

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.

This recoil thrower has been on the market for years now. I read stories on cpf about how to mod it (mainly swapping emitters, but no one actually did it) and I have been thinking about the effect of using reflectors with different focal length, and the dissappointing conclusion for me was that the design as it is stock, with this reflector and the xr-e is quite about an optimal one. Actually similar to the Sipik sk68, most mods give results that are not a real improvement because the stock light did it right already.

But that was before I discovered blf and how far modding can go....

Time ago I swaped the xr-e with a xm-l. Here some pictures, hope they are useful.

Comparison with an spheric mag (both emitters at 2.8amp)

Mag unfocused to get the same size.

That looks well done :-) , thanks for sharing.

So what are your thoughts about the results?

These lights aren't designed for indoor white walling. Complaining about a semi-square beam indoors is a little silly (ok, a lot silly) since a focused die image means better throwing distance. Wait until dark when you throw that beam across the pond. ;)

I am a sucker for throwers, especially cheap ones!
Thanks for the info.

djozz: I prefear this light with the xm-l. Of course it doesn´t throw as much as the xr-e but still gets far away and with lots of light.

JohnnyMac: Yes, you are right,; not for white walls but I wanted to show the diference with a known flashlight. Anyway most of my lights are “silly”, with not use for them, only the pleasure of making diferent type.

Or do you think there is a use for a AA flashlight with a SST-90 and only 10 secons before you burn your hand? :bigsmile:
