I have installed 120V photo cells before, but was thinking today how you would use a photo cell to control a H.I.D. fixture that is 240V? I have never seen a 240V photo cell. Do they even make one? Thanks.
WE keep on hand the twist on ones (Dusk till dawn) that accept 120 to 277 volts and flex end type that also accept 120 to 277 volts this way our inventory is kept low. There made by Intermatic.
