When I was searching for Luxeon datasheet, I found a new product, the Luxeon Rebel series. Quite interesting product, in terms of dimension and light density.
Unlike the other types, this Luxeon is a surface mount LED. Over 150°C junction temperature with >80 Lumens in cool white at 350 mA. This LED supports up to 1000 mA current (nice!). It claims 50.000 hours life at 700 mA. From the datasheet, we can expect up to 145 Lumens at 700 mA (LXML-PWC1-0080). It’s available in various color (cool white, neutral white, warm white, green, cyan, blue, royal blue, red, red-orange, and amber). The white version can support 2670K-3500K (warm), 3500K-4500K (neutral), and 4500K-10.000K (cool) color temperature. Very flexible. Its typical forward voltage is similiar with other Luxeon (around 3.6 Volt or 3.4 Volt for red/orange/amber).
I tried to contact some distributor like Farnell to get this product, but currently they don’t carry the product. Will have to wait a month or two 😉

May 4, 2007 22:20I have in my possession 30 royal blue Luxeon rebels and 30 cool white rebels. I knew they were small when I ordered them, but in real life they are small! I currently work with Luxeon 1 watt emitters making landscape lights that operate on 12 volt dc. These emitters are easy to work with by hand soldering to the anode and cathode contacts.
Do you know of anyone that can make circuit boards to use these new devices? A large array of these devices, maybe 10 emitters on a heatsink circuit board would make a great area light. The possibilities are endless, I do not have the means to work with surface mount tiny devices. If you are interested in these Rebels drop me an email.

Where did you manage to get these from? i need red, green and blue for evaluation.

July 4, 2007 01:22Les, The Luxeon Rebels can be purchased from Future_Electronics.com
I know they have red,green and blue in stock. You will need to open up an account with Future Electronics to purchase them, it isn’t a complicated issue to sign up, but you need to sign and fax a document to them, it is an export document about reselling these devices.
I hope this helps,

November 22, 2007 17:10I got my Luxeon Rebels from http://www.dotlight.de they seem like a good supplier.
The Rebels are very very small, smaller than a match head.
Mounting them looks really awkward unless you have a custom PCB.
I’m going to try soldering them directly to a copper slug then glue/screw this to a larger aluminium heat sink. The advantage for me is that I only have space for a single lens so have two rebels very close together should still work.
I intend to use the guts of a cheap DC-to-DC converter (cigarette lighter socket PSU) to make a voltage step up.
Cheers

February 11, 2008 17:19We just released a board for the Rebel LED. It’s really easy to use and with solder paste and a heat source you can mount your Rebel LEDs by hand. We call our product the Rebel Square. It’s a 3 LED layout. We’ll be producing another design for a circle (6 LEDs) in about another month.

March 26, 2008 04:09Thanks to Keith Summers and his great circuit boards for Luxeon Rebel LEDS.
I purchased 100 from Keith. I never soldered a surface mount component until I received these boards. Placed a quality solder paste on the pads, heated the board on a hotplate and magically the solder melted and the surface tension pulled the Luxeon Rebel into perfect alignment. Soldered fifteen circuit boards in one afternoon each with three Rebels onboard. Pretty easy to do, and you should see the insane brightness of the Rebels! Can’t wait for the warm white LEDS with over 75 lumens at 350 milliamps of current, I have some serious Outdoor Lighting projects waiting to happen when these hit the market! Thanks again Keith, looking forward to doing more business with you.

March 31, 2008 02:33Just found this site… I sent some Rebels to Keith, and he custom mounted them for me on his boards – for thouse without Jim’s guts to DIY. Turned out GREAT! The fee was MORE than reasonable.

April 16, 2008 23:25Hello Gentlemen,
Thank you for the kind words. I’m very excited to hear of your positive results with the Rebel Squares.
Those who want to know more about mounting the Luxeon Rebels, please click on my name to be taken to my web site.
Thanks, Keith

If you are looking for soldering advice, I would recommend reading over the following article. It talks about soldering surface mount LEDs, such as the Rebel, using standard soldering stuff. No oven required. http://www.lunaraccents.com/LED-solder-tabs.html
Keith
May 26, 2008 18:43This reference to an article about soldering LEDs is typically for those who have a reflow oven of some type. I don’t recommend this for those who use my board for small scale work. My boards have a metal bottom which allows you to heat from below with little to no risk of danger to the LED on the top of the board. This is a big difference in complexity. The article goes on to suggest using a toaster oven — with my product, that is the difficult approach. Using a small hot air gun is all that is required and you see easily see the work during the procedure.

Please advise me a distibutor the Luxeon Rebel in Indonesia or Singapore, thank you

September 28, 2009 20:41Fendo, distribution in Asia is weak. Offices out here are not very efficient. Here is the problem — stock of Luxeon Rebels is first generated in Singapore and then shipped out to 2 or 3 other locations around the world (US & UK). So, you may end up dealing with deliveries from any of those locations. Also, Singapore can’t deal with a credit card.
So I deal directly to a representative in Canada (main coorporate location for Future) and let them do my processing. They are fairly efficient there. However, that doesn’t mean they still don’t make mistakes. But, there are less mistakes made there.
If you can deal with Singapore, then they may be willing to take your orders — but you’ll have to wire them money through banks T/T.

November 20, 2009 23:37Have a look at http://www.luxeonstar.com/
They carry the Rebel, and if I’m not mistaken, they are working on a process to sell them pre-mounted in any configuration !
Cheers !

March 25, 2011 07:28Hi Just thought I would add my two cents worthon this subject. I have just hand soldered about 150 of these little guys onto some pcbs using fine solder and a fine tip iron. My first attempts were a little dodgy but got the hang of it after a while.
Firstly, I have my Iron set to 350degC. if you go too hot, the LED can fall apart. I hold one of the leds between my finger and a rough desk surface and just put a LITTLE (VERY little) solder on the led pads. Just a wipe to coat it. if too much solder you will have trouble mounting them exactly vertical. Just enough to colour the surface of the pad. wipe excess off if you can. and make sure there is a little on all three pads.
Next position the led on the pcb pads. Important: if you plan to do this by hand with regular iron and solder, make the pads on your pcb large enough to protrude from the ends of the LED. again put a tiny smear of solder on the pcb pads. if too much is on and it forms a round bubble, then clean your iron tip and remove some solder from the pad.
Withthe LED positioned square and some pressure downwardswith your finger, place the tip on one of the pads(anode or cathode) and the smear of solder on the pad with flow up to the led pad underneath. EASY. next do the other pads. If too much solder is on the pads, then it may cause the led to be raised too high, or on an angle, especially if pressure is placed on the pad..
be carefull to not heat the led too much. the solder should flow onto the joint and led within a second.. let the first pad cool a bit and keep the led inplace before you solder the second and third led pads..
good luck
