Glow of 490nm wavelength is most perceivable for squid.

“490GLOW” is one of the YAMASHITA’s exclusive technology.

For many years squid anglers all over the world have used jigs equipped with glow material. Now, research shows the best wavelength of visible light squid is 490nm.This is a tuned glow of 490nm which YAMASHITA discovered with the researchfrom a leading Japanese university is the best glow color for the squids eyes to detect.”Glow of 490nm wavelength is most perceivable for squid.”
