Magic shine has been around for a decade at least, you know they’re not random weird Ali Amazon stuff.

My new light is floody and I put it on my handlebars. My old Cygolite is spotty and I moved it up on my helmet. I wish they were the same color. My new light is very medium color (listed as 4000 kelvin) and the Cygolite is much cooler/bluer.

You would not believe how far you could nerd out with this stuff, but suffice to say it’s possible to DIY and build exactly what you wish if you can figure it out
