For my bike light, I modded it to triple 2700K SST-20 LEDs (What did you mod today?). The original was a cool blue LED.
Not only is a 2700K bike light a rarity to see these days vs the incandescent bulbs of the past, it is also much easier on the eyes. And since it’s an older light, the brightness is not all that bright, about 300 lumens.
I also point the light down in front of the bike unless I’m riding on streets and competing with cars.
It is annoying when I’m on a later jog and come across someone with a very bright light. I put my hand in front of my eyes to block the lumens, but I’m not sure if the message is received. They may instead think they have an awesome light!
