Halo LED built up lettering

[Robert Lambie]

something ive never done myself mate, but ide imagine your supplier will have spec based on how much each LED has rich. multiply that by the amount of LEDs per letter.
ide imagine there will be a drop based on defuser used etc but at least this way you will have a max amount to give indication?

as i said, not my thing… 😀
