They aren't 'on' green or silver anythings, that's the color of the material they're made of. A green XM-L2 would probably be about as common as a 4-door AC Cobra.
Condescending what? You were asking questions common for somebody who doesn't know these things, I was trying to explain that the green part and the silver part is the LED itself, not some other component. They both have the same solder pads/footprint on the bottom, they can be soldered to any board made for that platform.
And where the hell do you see a green Sinkpad?! I see a post with two black aluminum MCPCBs, and another with a white 20mm Sinkpad and a white 16mm Sinkpad...
Bare XM-L on left, underside on the right showing the + & - contacts, and big thermal pad in the center
XM-L and XM-L2 share the same dimensions on the contact pads on the bottom, they can be interchanged on any board that uses the 'XM-L' layout. There are other brand LEDs that use the same basic footprint and they can all be used on the same boards.
It certainly is a part of the LED. I think the actual name for what we normally call an "LED" is an LED package.
The actual Light Emitting Diode part of the package is the die, so technically, lionheart wouldn't be wrong in asking what is the green thing that the LED is sitting on, cuz that would be another way of asking what is the green thing the die is sitting on.
But generally, I think we refer to the entire package as the "LED" and not just the die.
No problem, you’ll learn. Just keep in mind this can be a very technical hobby, like cars or guns, or like physics and chemistry, and terminology can sound similar for different components, so the correct terms are important.
When the LED are off you can see darker color when the tint goes to warmer tint (mistaken doxa,infact it is cooler).
Cool white are lemon yellow, warm white is orange because there is more phosphor on the die.
Wow, I’m learning in this thread…didn’t even know the SC52 came in a XM-L2 emitter, I thought only the brand new SC600II’s did. I guess it’d make sense for them to update their emitters across the board.
