Rated 2 out of 5 by Balzac Too low visibility
This 425 nm LED is a true violett LED but if stringed with other colors like blue, red, green and amber its visibility is way too low due to the relative insensitivity of the human retina; a much more acceptable solution would be a mixed red-blue LED with a visibility similar to the other colors.
