We have a gas outdoor lamppost and would like to replace the top with an electric light instead. Advise please?

Install a switch using regular NMB cable or Romex providing power from any power source from general lighting circuits.

Just tap off of a nearby receptacle and fish a 12/2 Romex to a switch box in the wall where you want it. Then run a 12/2 from that switch box to a junction box just in the crawl space at the point of leaving underground or to a weatherproof junction box just outside the house. Now switch to a 12/2 UF cable running the cable buried at least 18" underground, from that junction box to the gas light pole. Be sure to plug off the gas line at the house. Then drill a hole in the lamp post and fish the UF cable up the pole. You will most likely find cement in the ground holding the post up solid. If this concrete is too close to the surface to drill the hole for the wire to enter the pole underground then use a 1/2" sweep 90 rigid conduit to loop from underground into the pole above ground. Be sure this loop of conduit is solid and strong enough to take a beating from lawn mowers, etc. Once you have the UF cable to the top of the inside of the pole the wire black to black, white to white, and bare to green of the electric post light fixture. If you are using a receptacle in the post light pole then the UF cable must be GFI protected. If the cable is GFI protected then you reduce the depth of the trench to 12". If you are using a photocell to control the light then just wire this photo cell between the light fixture and the UF cable.
The switch just wire nut the bare to bare and the white to white, then install the wall light switch to the two black conductors.

Good Luck
