Thanks, did this myself, using Noctilumina. Noctilumina appears to be a bit less bright when compared to the Lumibrite used by Seiko, but once the Lumibrite fades a bit they are both the same. The new stuff from Noctilumina last all night and is still very visible in the morning. Does not appeat to be any difference between green and blue. I prefer the blue lume over the green.
