ROFL! I follow a Facebook Ozone/UV pool group and a member posted the below. I think this is part of the marketing having this green "oooh! ahhhh!" effect of the light. Sad to read posts in this group their main thing is to see how little chlorine they can use.

It’s little green alien technology you know. It needs to look cool to prove it.
