my state where I live is a state of OVX! I know one member who said "I visited MD and I have been OVXed!" most of our OVX owned by the state are 250 watt HPS and most newer ones are FCO. Our earlier ones were drop lens and actually still lives today! Our oldest OVXs are believe it or not ALMOST 20 years old! There is one OVX recently installed due to a downed pole...and it was the first time I saw a drop lens OVX installed.....in a long time!
