Do anyone buy the Ultrafire UF-007 (Recoil Led)

[ming560]

Today just buy a Ultrafire UF-007 (Recoil Led), do anyone have it?

I've never seen it before. Where did you find it? And more/higher resolution pictures please. Body looks nice.

Looks weird. I'm wondering about LED cooling...

Looks interesting. This could be a contender for throw as something like this can truly collimate light effectively kinda like a reflector telescope. A light like this probably has a tight spot with no spill.

ditto... where'd you get that?

I would like some info as well.

I guess the led being on the window might help it cool? Very interesting!

 

[horizonseeker]

same here, since google turned up not much I would really appreciate a source.

Pelican has some recoil leds also.

COME ON GIVE IT UP!

It is unique and I must have it.

I found this site the other day:

http://dmcleish.com/CPF/Spherical-Reflector/index.html

It set me thinking about that setup. With aspherics you get no spill, the light coming out of the sides of the LED is wasted and contributes nothing to the beam. With a reflector, light going forward out of the LED misses the mirror and goes out as spill, its not wasted but contributes little to the spot. With that reversed diode setup all of the light coming out of the diode reaches the mirror (although some will be blocked by the LED / wiring /support).

If you design the mirror and make it with good precision I think one of these could outperform an aspheric. Who is going to buy/mod/make one to prove it?

Heatsinking was the problem I could see, I thought that if you made the lens out of monocrystaline diamond it would probably solve the problem, failing that an aluminium bar from one side to the other carrying the LED in the centre could remove some heat.

I'll start with seeing how this one works out then mod it from there.

I'm not 100% sure if this is going to work (the google translation), but I found this:

Cool, better pics of the Led post and a beam shot!

Thanks for finding that.

Awesome looking light er I mean laser. Imagine that think with a MC-E led . Don't need it, but looks like a fun light to play with .

Is this the james bond flashlight?:naughty:


I think it says in chinese: throws up to 300m.

Isn't recoil led trademark by pelican (or streamlight, anyway it's one of the bigger u.s. manufacturers). That's basically what they do, claim to capture all the light. However they moved away from it when high powered LED came along.

Yes, "Recoil LED" is a registered Pelican trademark. I don't think they've moved away from it so much as all their offerings cater to police, who don't want a beam with no spill. The recoil design is still the best reflector shape to cut smoke or fog. That won't change.

A spherical reflector will perform terribly. Anyhow, there's lots of loss associated with reflecting surfaces. If you want high efficiency and high lux, then you want a large, high-quality TIR optic. Those have throw equal to an aspheric lens of equal diameter, but with efficiencies that can top 90% in some (expensive) cases. Your average plastic optic runs about 80-85% efficient and your average reflector setup is about 75% efficient.

I got it at Hong Kong and the price is reasonable and not so :devil:...hehe..
The seller told me that the LED is cree P4,
4 mod: high, media, low, flash.
voltage can use between 2.7V~8.4V
( which mean you can use 2x 123A, 1x18650, 1x17670, 2xR123A)

The light beam is square and not a circle.
It is a long thrower flashlight.

Due to lack of time, may be taken some light beam today to compare with the others flashlights on hand.:devil:

 

[Sgt. LED]

If it's openable without destroying it, it must be modded to an R2 at least!

 

[ming560]

It can be open but may need some special method to change it.
Some guys told me that using rebel or dragon plus will have better light beam.
May be the new version of Cree will be better!
