If you do get around to testing the Ushio lamp with the phantom de ballast with your par meter please be sure to post back your findings hereI also know there are claims that the frequency and amplitude of the input voltage has a lot to do with spectrum and lumen maintenance. This makes me wonder how the same lamp performs on different ballasts. Big old rabbit hole to go down when you start talking spectra.
