New resistor values for Glasgow system LEDs. I think I got them pretty reasonable.pic.twitter.com/h4jUCXcNF1

Introducing a new standard for LED indicator brightness: your LED should be bright enough to be clearly visible when illuminated by a FireSword V in high mode at 1m distance. And NO BRIGHTER.pic.twitter.com/81XcBo2yir

Lower exposure with the FireSword, they're clearly visible.pic.twitter.com/Z1ZToZibr9

Note that that last photo isn't in the dark, it's with normal room lighting and lowered exposure. They definitely aren't *dim*. Here's an actual shot in the dark and one in normal lighting and exposure. The camera exaggerates them a bit though.pic.twitter.com/SSpvkfE5Xe

For reference, when I started they were 10 times brighter or so and hurt my eyes *even through a layer of tape*.

These are the resistor values I ended up with. Yes, the currents are in microamps.pic.twitter.com/3XE2r5rlib

Agree. I doubt the standard will catch on though. We will continue to be blinded by nerds :(
Thanks. Twitter will use this to make your timeline better. UndoUndo

I am always designing to the “20mA draw” figure for initial resistance value and that is far far far far far too much current for most modern LEDs. It’s astounding how bright some of the high efficiency ones are at a few hundred uA!

The original design here was for 300µA for the greens... that was still blinding behind a layer of tape. I lowered it to 55µA. That's what you're seeing in those photos. It's still somewhat uncomfortable to stare directly at in medium lighting. Yes, 55µA.
