I fixed a power wart LED today using black electrical tape, with a needle hole.
Ideally instead I need some stick-on semitransparent dark-alpha stickers to reduce brightness. Maybe I should use two polarized stickers, and rotate the second until brightness is perfect.
Are there non-linear solutions or HEV-sensitive photochromic solutions - so that LED brightness is low in the dark but bright enough in sunny conditions?
I sure wish that were a thing, if you happen to figure that out let me know. So far the only real solution I know of is active throttling with a photoresistor and a mosfet based on ambient light.
