Hello
I need to find out what are the most common voltage levels used in street and public lighting for the below lamp's types. Better if percentages of use are provided.
M.V: Mercury Vapor
H.P.S.V: High Pressure Sodium Vapor
M.H: Metallic Hallogenous ?
I have seen specs for 120,220,208,277 and 480VAC, which ones are the most popular?
Thanks in advance for your help.
