any use of luxeon rebel?

[2jzpower]

is there a flashlight that uses the luxeon rebel so far???
i don't know much about this LED but is it brighter/more efficient than seoul or cree?

i also remember seeing that it was quite a bit smaller so more intense lightsource = more throw???

Maybe the new inova X1, I think I read that, but I'm not 100%.

Not sure if this UltraFire B1 use Rebel, but the shape looks similar.

i thought the rebel was supposed to be putting out about 160 lumens

Maybe the new inova X1, I think I read that, but I'm not 100%.

Hopefully the next version (4th generation) will, but per Matt at BatteryJunction.com the new 2007 version uses a "LXCL-PWT3 Luxeon PWT". Here's a link to the PWT1 version:LXCL-PWT1

Comparatively speaking that looks like a terrible emitter... 26lm @ 350ma is horrible based on what else is out there. Any ideas on why they didn't go with an emitter that could do 26lm at a fraction of the current to get some really enticing battery life?

I agree. According to the two frontal pics, the led is a Luxeon Rebel. $11.26 sounds nice to be among the first owners of a flashlight with this led.

 

[MattK]

I don't think that's a rebel for 2 reasons;

1 - it looks just like the LXCL-PWT3 in the X1.

2 - From what I've been told the first shipment of Rebels won't even LAND in China until the second week of June.

ergo - not a rebel.

Don't expect to see the rebel in high current throw light applications - the Cree's are still the emitter of choice for that. The Rebels will excel in small format, low current lights.

as there have been so many treads on this, imho its ok to type:

"crappy led, not up to Lumileds marketing (who wonders?). If You want to know anything more, just use the search function"

The only flashlights I have heard of, that will be using the Rebel LEDs is manufactured by Quantum Lighting Products but that DealExtreme flashlight sure looks like one.

Here is a press release dated march 30th 2007.

KOWLOON, Hong Kong - HK - Quantum Lighting Products Limited, the leading portable illumination products manufacturer in HK, will introduce several portable illumination products featuring the latest Luxeon® Rebel LED from Philips Lumileds in HK Electronic Fair Spring Edition from 14-17 of April in HKCEC (Hong Kong Convention and Exhibition Centre).

As the first manufacturer in HK to announce the use of Luxeon Rebel® LED, Quantum will demonstrate the new design torches and headlights using the powerful light source. The new Luxeon Rebel® LED can be driven from 350 mA to 1A to offer the brightness up to 176 lumens.


Gosh, it's hard to believe but this is my post # 500 . I'm going to get a star (*) for this one

 

[Illum]

if I have access to alot I'd probably epoxy them in grids....why bother with a single die star when you can sandwich more in?

 

[MattK]

Quantum makes some decent lights for companies like Nuwai, eGear, LEDWave, Night-Ops and others.

 

[2jzpower]

hmmm 176 lumens at 1a sounds good to me... looks like it'll throw too considering the light is coming from such a tiny area.... and think of the multi emitter possibilities

 

[RustyKnee]

I beleive that die size is the same as the XR-E and Seoul. Its just that package that is smaller.

i got 13 rebels from future electronics a few weeks ago, the 95 lumen version. while not as bright as cree/seoul, they are cool in their own way. they have a rosy tint, seems a little purple almost, and they are perfect for button cell lights. i made a reading light that runs on 2x 2032. very bright for such a tiny light, almost too bright for a reading light. with those batteries you need just a teeny tiny heatsink. thats 6v with lots of initernal resistance, so the light is bright enough to read by even when the cells are practically dead. and at $2 apiece, why not? would also be good for night-lights.

I designed a new, small diameter reflector for the Rebel and I will be curious to see the results. Although the die is not small as already stated, the small package as also stated, may allow for some solutions not available from the present time high output performers of the EZ1000 base. The smaller package and smaller price should give the Rebel an edge in certain designs as well as price points I would guess. If the drive levels are low and the light a small format, the Seoul 1/2 Watt LED has the advantage of a lower price and a smaller die so one can get greater collimation from a similar format; perhaps higher lux even though lower flux.

I think the Rebel is a definite player in the new games but it is not clear yet what those games may be or how the Rebel will be most effectively deployed.

Me too! Is McGizmo going to enter the race between Modamag and Orb
to produce the smallest brightest light?

It is not the die size that defines the ability to collimate, but the effective source size which takes into account the packaging. I am trying to get the effective source size from Future\Lumileds but I do not have it yet. While it is the same die size as the K2/LuxI/III, due to the optics of the packaging, the effective source size appears to be about 30% less by my estimates. You can see this by trying to estimate the die size with a rule. If you try to measure a K2 die with a ruler from outside the package it will look about 2mm on a side though it is actually 1mm. For the Rebel, it looks like about 1.4-1.6mm.

Trying to find the Seoul 1/2 watts I tested, but I do not think their effective source is any smaller so they are not going to collimate any better.

 

[McGizmo]

Semiman,

I agree with your comments and stand corrected. I did find though with the Seoul 1/2 watt that I was able to get a tighter spot from the same optic used with one of the larger LED's and I consider it to have a smaller effective source size or image size or what ever term one would find acceptable. I have not done much with the Rebel yet because I have no need or desire to use it in lieu of a Seoul P4 or Cree in any of the existing packages I have been messing with. If it does have an effective size smaller than the others then that is a plus in small format packages.

Ultrafire seems to be the first manufacturer using the Luxeon Rebel on their lights.

There is a version rated at 1W of the Ultrafire B1 that you can find on szwholesale and qualitychinagoods

They are under the category of Luxeon lights, and it is a new model (introduced on May, 9). If you look at the second pic, you will see that the led is a Luxeon Rebel. The light only works with batteries providing more than 3V (lithiums, direct driven led?), so I am not interested in this model, but it exists.

The second model seems to be a 0.5W rated variant of the first one. You can find it on dealextreme. The led IS a rebel and according to the site it runs also on 1.5V standard AA batteries. If it runs also on NiMHs, then I am interested in this light!
