1. Basic Meaning of Wattage
Wattage (W) refers to the power and energy consumption of a bulb.
Brightness comparison: LEDs are 5–10 times brighter than incandescent bulbs at the same wattage.
Selection logic: Choose wattage based on space size and usage, not the higher the better.
2. Common Wattages and Applications
Low Wattage: 1W–5W
Soft and mild light, suitable for night lights, cabinet lights, corridor sensor lights and decorative lighting.
Medium-Low Wattage: 6W–12W
Moderate brightness, ideal for bathrooms, balconies, corridors, storage rooms and small bedrooms.
Medium Wattage: 13W–18W
Sufficient brightness for daily use, perfect for bedrooms, studies, dining rooms and small living rooms.
Medium-High Wattage: 19W–30W
Bright and uniform lighting, suitable for large living rooms, offices, classrooms and shops.
High Wattage: Above 30W
Ultra-bright for large areas, used in factories, warehouses, halls, courtyards and street lights.
3. Quick Wattage Guide by Space
Below 5㎡: 5W–10W
5–10㎡: 10W–15W
10–20㎡: 15W–24W
Above 20㎡: 24W–36W
Industrial / Outdoor: Above 50W
4. Key Selection Tips
Choose higher wattage for larger spaces.
Higher brightness for reading and working; lower brightness for rest and atmosphere.
Prioritize LED bulbs for energy saving and longer life.
Warm light for bedrooms; white light for living rooms, kitchens and offices.
Summary
Wattage is the core standard to match space, function and comfort. Low wattage is for atmosphere, medium wattage for daily home use, and high wattage for large areas and industrial scenes. By selecting the right wattage based on space size and using LED bulbs, you can get suitable, energy-efficient and durable lighting for all scenarios.
