I'd have to ask @speckacuda on how the QTC material would react, but you can mount an SBT90.2 on a 16mm board.

There's a lot of super lumen LEDs that are available.
SFT40 would be nice

@speckacuda - How much current can you pump thru the QTC material? SFT40 would be super nice. SBT90.2 is kinda pushing on that too much side, but SFT40 is an excellent all around super-lumen LED.

SFT40 and 519a about to be ready to go in the Nugget

SFT40 will hit 2600 lumens at 10 amps, 2,000 lumens at 5 amps.

But with lumens comes heat and heat kills the LED eventually.

I prefer nice tint and balanced output like what the 519a can do, but I have these to try

I have them all except 519a 4000k. I can’t find them. I have all of the 219b, which is still a fantastic LED.

Here are all of the R9080 offerings:

And you can dedome the 519a to change the tint, too.
A 4500k dedomed is around 3500k. A 5700k dedomed is around 4200k.
5000k dedomed is perfection. @PoliceScannerMan can tell us what tint that is…I don’t remember off hand.

@Berserker26 - I make these. Some I get made because it’s cheaper, but any Nichia I do myself.
