    I have some double .75 gauge cable and was going to use it to add two 60 watt led wall lamps to shed. Would it do the job.

    What size circuit breaker is on the circuit or are you running it off a fused spur?

    Unless the cable is suitably protected via an adequately rated circuit breaker or fuse then it is not safe to use it.

    I am just adding 2 more lights to existing light that was there already so I have now 3 lights instead of 1 I will have 60 watt led bulbs in 3 of them.

    With the greatest of respect, if you have to ask the question you probably shouldn't be doing it.

    How big is the shed ? They are pretty big LEDs.

    60w LED? You trying to light up a football field?
    If as I assume you are talking about 60w equivalent (so maybe 9w LED bulb)...

    Anyways, either way, you are fine with the 0.75mm

    Don't be smart this is a DIY forum and I am looking for a second opinion.

    And there's no need to be defensive, I'm just offering my opinion.

    FWIW my personal preference in this application (a shed) is to wire LED lights using low voltage DC (12V or 24V) and limit the mains runs to a short distance between fuse box and a single well-speciifed transformer. There's no need to be running mains cable for lighting in 2020, although you do have to be careful about voltage drop.

    But I'm not an electrician and know my limits. :)

    Go get some 1.5mm^2 cable and do it right. Existing light circuit is most likely protected by a 10A breaker (you should confirm this). You don't size the cable on what might be drawn from the light, rather you ensure it is capable of carrying more load than the breaker allows.

    Someone could come along in years to come and put in a bigger/different light that will overload the 0.75 cable.
