So they say fluorescent lights are more efficient than incandescent and HIDs more efficient than halogen etc.
My question is, how is that so if the gas discharge style lamps require a higher voltage to operate? Is it more of a reference to the efficiency in terms of light output being brighter rather than actual energy used?
