As the name implies, the light duty cables are used for lighter application eg. flexible control cables, building wires, single & multi-core flexible cables for panel wiring, appliances wiring, flat cables for submersible cables, CCTV cables, indoor telephone cables, screened cables etc.
You can use 2.5mm wire for lighting. However, 2.5mm is thicker, less flexible, and more expensive. The standard cables for lighting are 1.5mm.
Aluminum, copper, and high-strength alloys are the main materials you'll find at the center of your wire and cable. Each of these metals have different properties and levels of conductiveness so it's important to know how they could affect your next cable or wiring application.
Light-duty cords are created with low amperage compared to heavy-duty cords since light-duty devices draw less current than heavy-duty appliances. For example, a lamp consumes as low as half an amp while a leaf blower draws up to 12 amps. Most light-duty cords can't handle the current needed by a leaf blower.
