What is the voltage for airport runway lights?

Question

What is the voltage for airport runway lights? and how are they wired, in parallel or series? What or who controls them?

Answer 1

They are 230 VAC  and wired in parallel so the lights don't all go out at the same time. In inclement weather the tower does, but on a normal day they turn on just like street lamps.

Answer 2

The lights are wired in parallel, and they are controlled by the tower, which determines their intensity, too.

At airports without a tower, lights can operate automatically or they can be pilot-controlled (by keying a transmitter on the advisory frequency for that airport).

If the tower is closed, lights can be operated by the same methods as non-towered airports described above.

Answer 3

They are powered by mains current, 115 or 230 volts.  They are wired in parallel.

At most tower controlled airports, they are controlled by a dimmer so they can be adjusted for visibility conditions.

At many remote or uncontrolled airports, the lights are activated by a system called PCL (Pilot Controlled Lighting) so that approaching aircraft can turn them on and they don't have to stay on all night.

Answer 4

Uh don't know for sure who or what controls them, they are almost definitely wired in parallel, and they are either 277 or 120, unless they are some really odd DC voltage, or they might have a ballast too so yeah.
