RE:Upside of Vertical TechnologyThanks Johnny for your great insight and time you spent compiling that info. The only thing I would add is that in the latest news release, AFI said that they're trialing the latest LED technology, which I would assume is replacing the HID. Because LED is more efficient it also generates less heat which would hopefully get rid of the need for cool tubes. Lower cost, greater efficiency. We seem to have a top of the range product here.
