Start with the room and the purpose.
Consider where light is needed for tasks, movement and general ambience. Table lamps, pendants, wall lights and outdoor fittings have different roles, but suitability depends on the verified specifications of the individual product.
Plan several layers of light.
A combination of ambient, task and accent lighting can give a room more flexibility than a single strong source. The number and position of fittings should suit the room, the electrical installation and the intended use.
Check product-specific information.
Before buying or installing a fitting, confirm its dimensions, voltage, wattage, lamp or LED type, dimming compatibility, ingress protection rating, location restrictions and installation requirements. Do not rely on general room imagery for technical suitability.
Use qualified advice where required.
Electrical installation and compliance requirements vary. Use a suitably qualified electrician and follow the manufacturer's verified instructions and applicable Australian requirements.
