First of all, to judge which lighting power supply is suitable, we need to establish what shape, what type the lighting will be, where and how it will be placed and what it will be used for. Lighting for the home or office, for example, that is available commercially can be accent, auxiliary or main. It can also be designed for outdoor or indoor use. Commercial and industrial lighting also have different uses, which in turn will require different power supplies.
In addition to powering different types of lighting, power supplies can also act as a transformer, stabilizer or protection, absorbing various types of voltage peaks and dips and preventing conditions that can damage the lighting fixture.
