So this Iron Man keycap I purchased from Keypop isn't lighting up as much as I hoped. (Poker II on max brightness) I figure it is because the LED is behind the switch... Is there anything I can do to make the eyes of the keycap glow brighter??? Thanks!
All Iron Man keycaps come coated with gold or silver inside the keycap. Silver does indeed reflect more light than gold but I cannot guarantee that you will see a considerably large difference as gold does a decent job of reflecting as well.
It may seem dim because the opening of the eyes aren't that big to begin with.
I would strongly recommend switching to a brighter LED.
