Some houses seem to have a switch where you can control the landing light from the hall but others do not. Im definately aiming on having a switch that controls the hall light from upstairs, but is it worth having a switch controlling the landing light? Reason being Im having a pendant, stair leds, wall light and landing light which can all work off a 4 way gang. If I want to control the external lights its another switch or a three and a two gang. If I dont hae the landing option it'll be just a four gang. Do many of you use the landing light option from the hall?
