EcoTech Radio Upgrade

[reefmandan]

Hey Guys,

I was wondering if anyone had purchased upgrades on the Ecotech Radion lights. I have two G1s, that would like to add the U.V. light to. As far as I know, EcoTech will upgrade to G3, G3-pro clusters,. I know the pro has yellow, and increased intensity, but the price difference for the upgrades is $100. I'm just wondering if anyone know if the only difference is the yellow/intensity?
