Is there a source somewhere for the PC Rebel on something small and round, like a 12, 14, or 16mm base?
(I know I can get them on a 10mm square (Luxeonstar) or 20mm star (LEDTech))
Or, what empty base do they fit on and where might I find it? I can warm up the heat gun
I have not seen anything other than 20mm and a 10x10mm square board for the Rebel. A 16mm base can probably be made by filing/sanding down a 20mm one.
Actually I have quite a stash of 20mm Rebel Sinkpads and I'm not at all going to use them all. If you are interested I can sell you some for what I paid for them (if I remember well 0.70 cents/piece) plus shipping (2.20 dollar to the US).
I have some 20mm boards also, i am lazy/reluctant to start filing on them, not sure how much I can remove without hitting a trace that I don’t want to file away.
I’m hoping someplace sells Rebels mounted. Or even any appropriate bases I can learn hot air work on, in 12-16mm intermediate sizes.
I have filed a few 16 mm. stars to 12 mm. I have to scrape the top layer off the traces to expose copper to solder the wires to.
I think I have bought them on 16 mm. stars, but I can’t find where. Perhaps that was not in the description.
I tried a Luxeon Z a while ago, but making a copper board for them was a pain. I still have the little cyan luxeon z flashlight, gives a ton of light :-)
Wow.
Somewhere out there in the world is a 4xD M@g modded with four Cyan emitters, that I had years ago, til someone stole my car (sigh).
It was wonderful.
Nowadays I can probably get the same amount of light out of a single celled host …. time to try it again.
But I’m sure not going to work at the scale djozz does. That’s really beautifully done. Love the stereo images!
I just ordered a triple Luxeon deep red mounted on a direct thermal path SinkPad II.
Deep Red Rebel
It says max current 700mA, but also states that “Higher drive currents may be possible, but will require careful design of a suitable cooling system.”
I plan to run this DTP triple in an S2+ with a copper heatsink, and was wondering how high in current I can take it.
I have one of these leds and did a quick output test on a Rebel Sinkpad before doing the mod at the time. I never documented it but I think I remember that just like most colour leds 1.5A is a sweetspot, over 2A the output already drops.
I have three from rapid led on aluminium stars but only two are in lights. One is mounted in a 502b @ 1400ma and the other is in a JacobA60 at either 1750 or 2100ma. They have held up fine but can’t see lumen benefit from a ceiling bounce test. Both of mine are single mode lights with 7135 based drivers.
Hmmmm. After pretty much only using DD FET drivers for a while, it will seem weird going back to a 7135 driver. Like having an Amish flashlight.
So how many color emitters — in serial, and how many in parallel — would work and be enough to avoid blowing them up, feeding power through with a single li-ion and FET?
I probably need to just start blowing a few up to get this into my dense head, but any forewarnings would help.
I guess it depends on the cell you use. For three emitters to n parallel, you’d wan 4,5-5A max, so would need a real crappy 18650 with a protection circuit. I’m not sure what an 18350 would put out on DD, it could be the answer. Make my light an S2+ shorty.
Lifepo4 might be your answer. I used one to DD a PT54 red at about 8A. Don’t know about now but Tenergy did offer 3 different capicity/output cells. Typically high capacity Lifepo4 cells offer lower amperage output. Find some spec info. HTH
I posted my build for a Rebel deep red triple in the mod thread, but figured I should add the beam shots to rollinstone’s thread on coloured rebel emitters for thread integrity. It’s running at 4.5A.

Roxanne. ….don’t turn on the red light!
The deep red rebels are a bright cherry red as compared to the orange red of the XP-E2. These are nice emitters and pack a lot of light. I don’t know why everyone is a afraid to try a non Cree LED.
Bravo. And for cross-references, several others along this line fairly recently

OK. But are there any convenient places to get them not in bulk quantities and with shipping price not through the roof?
> convenient places
Depends mostly on where you live.
