DiY LEDs - How to Power Them

Which 400nm diode?`And that would probably fuk up the circuit, no? I'd be more tempted to add FR. I think voltage wise the Osram Square Reds are quite compatible, but their royal blue is 25% higer voltage.

If they are in series as you say then no probs with using different voltage, they just add up. Would be a hard board to aource drivers for though, 57-58V board.

Well the Nichia 405's are like 4V+... Not really an issue adding 2V, but wouldn't you have to do it to every circuit? and there are 6. But overall 660nm would take a hit?

I've decided though... I wouldn't add anything other than far red to the circuitry, unless there's a good argument that the 405 lifespan us the same, which ut seems there may be some doubt.
