Can somebody suggest me what all i would need to install the spotlights in my garden?
Hi @mann, welcome to Workshop.
My apologies, but could you please let us know if you are referring to a particular product or have you seen these spotlights in a project on the site or somewhere else? We'd be happy to help if you could provide a little more detail about what you'd like to do and where you might have got the inspiration from.
There's plenty of low voltage garden lights that you can install yourself without the need for an electrician.
Obviously anything that is not low voltage though you would need to contact an electrician to install. Please don't DIY any electrical work - use a licensed tradie.
