Wattage in lighting

Wattage in lighting indicates how much energy a lamp consumes while it is in use. Power is expressed in watts (W). In the past, wattage was often used to determine brightness, but this is no longer the case with modern lighting.

Why is wattage important for lamps?

Wattage mainly indicates the energy consumption and efficiency of a lamp. The lower the wattage, the less electricity the lamp uses. This is especially important when choosing energy-efficient lighting and controlling your energy costs. Today, a low-wattage lamp can produce just as much light as an old high-wattage bulb.

Wattage and light output

With modern lighting, such as LED lamps, wattage is no longer decisive for the amount of light. Instead, you should look at the number of lumens. Lumens indicate how much light a lamp actually produces. For example, a 5-watt LED lamp can have the same light output as a 40-watt incandescent bulb.

Wattage comparison by lamp type

Different types of lamps use different wattages for the same light output. LED lighting is the most energy-efficient, followed by energy-saving lamps. Halogen and incandescent lamps consume significantly more watts to achieve the same level of brightness.

What should you consider when choosing the right wattage?

When buying lighting, do not focus solely on wattage, but mainly on the combination of lumens, colour temperature and application. Functional spaces such as kitchens require more light than ambient lighting in living rooms. By choosing the right wattage in combination with the correct number of lumens, you save energy without compromising light quality.
