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

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:

2 days after paying for this light and it is in my hands!
Now, THAT is some kick azz order processing and USPS being on the ball ( I think are upping their game lately, at least for USA domestic shipments)

Anyway, this puppy does indeed throw a nice light saber beam, Star Wars lovers unite :slight_smile:
And the buffed steel finish is total bling, the attack head is kinda sharp edged, but maybe that is the idea.

Overall, for $11.50 shipped to my door in record time, I am one happy puppy. Don’t need to mod it, I think they got it right the first time for the emitter being used.
Think of a SK68 zoomed in die pattern, but with more balls, and that is what this light delivers.
And with the low amp draw it should run a long time on a good 18650.
Thanks everyone for the good info,

I just got one of these lights (or similar) from Ebay today:

http://www.ebay.com/itm/281124338018?ssPageName=STRK:MEWNX:IT&\_trksid=p3984.m1439.l2649

the marking on the side says “Goread”.

I measure lux and got ~17Klux (from 11.39M, calc’ed back to 1M).

Has anyone actually tried (and succeeded) modding one of these? New driver? Replaced emitter? Resistor mod?

I have one with 2.8A 105C (luxdrv .030), dedomed XPG2 on a little sliver of what used to be a Sinkpad. Setting the focus correctly is not fun. J)

When the focus is right it will project a near perfect image of the LED, the wires, the outline of the board, the solder points, everything. So everything but the die itself has to be painted flat black. (out of the box, they are focused on the fuzzy side which mostly avoids that image-projection issue)

Does an increase in focus mean it throws further too?
