    I’m installing some lights in my shed and garage. Total wattage of lights is 310 to 350 watts. I need a double light switch. I need to know what wattage light switch would I need so that I don’t overload the light switch. I’ve looked on Screwfix and Toolstation and the only info they show is 230v power voltage supply. I’m finding this confusing. Please help.

    Most light circuits are limited to 6 amp, and I have never seen a light switch rated less than 6 amp. That's 1380 watts.
    So can't see any switch from Screwfix or Toolstation not being rated high enough.

    Most are now rated at 10A, good brands, that is.

    Is this the switch you are referring to?
    MK logic plus 10AX 2-Gang 2-way light switch (16201)
    Then yes:)

    Yes that is the one, but will it handle 3x100 watt led lights plus 10watt led light. Total 310watts.

    For future reference op :)
    Power (watts) ÷ Voltage (volts-uk is 230v)
    =Current(amps)

    So, 310/230=1.35 amps, way under a 6 or 10 amp max switch capacity.

    Buy yourself some welding goggles while you are at Screwfix. You are going to need them!

    You will when you turn on your 3x100watt LED lights.

    that’s enough for a whole football field.
