Wattage is the unit of power. When setting up household appliances, it is very important to choose the one with the proper wattage. The higher the wattage, the more electricity consumed, which means you will have to pay more for your electric bills.
So does lighting. When choosing a light with high wattage, the electricity will be high as well to produce bright illumination. But many researches show that too much light all the time is not good for the eyes or psychological health. Hence, choosing a matching wattage for lighting in different rooms is the lesson we need to learn before we purchase lamps for interior lighting.
In previous articles, we have introduced a lot about the knowledge of the lighting industry, color temperature, lighting design, lighting effects, etc. Today we are going to introduce something also concerned with money and lighting at the same time, wattage. For different spaces in the house, for example, entrance, living room, kitchen, bathroom, bedroom, children's bedroom, elders' room, stairs, etc.
1. Lighting wattage for entrance
Since the entrance is not so spacious for a house, it is enough to install a 5W downlight/spotlight. If there is no ceiling, you can also install a surface-mounted downlight, if you like a chandelier, you can also install one. The height from the ground is recommended to be 2~2.1, and 5W is also enough.
2. Lighting wattage for living room
The living room is an area with frequent activities of family members. It is not only the activity center of the family but also the place to entertain relatives and friends. It must be transparent and bright.
Therefore, the requirements for the wattage of the bulb are relatively high, and the wattage of the bulb is calculated according to 2.5~3W per square meter.
If a dining area or an open study room is set up in the living room, then these functional areas also need to add targeted lighting. For instance, in the reading location, it is recommended to place an arc floor lamp.
For the space of the living room, different dimension also requires different lighting wattage. Here are some corresponding recommendations for the living room.
Living room area: 20-30㎡，60-80W； 30-40㎡，100-150W； 40-50㎡，220-280W； 50-70㎡，300-350W； 70-80㎡，400-450W.
3. Lighting wattage for Kitchen
To reduce the inconvenience and danger when cooking, the kitchen needs to have adequate lighting without leaving dark areas.
Use chandeliers, ceiling lamps, or downlights, and calculate the wattage of the bulb according to 2.5~3W per square meter.
In addition, due to a large amount of water vapor and oil pollution in the kitchen, it is necessary to choose lamps that are easy to scrub, corrosion-resistant and oil-resistant to avoid smoke generated during long-term cooking and affecting lighting, otherwise, it will cause certain safety hazards. When wiping, clean with a dry cloth.
Kitchen area: 3-5㎡，8-13W； 5-10㎡，13-25W； 10-15㎡，25-38W.
4. Lighting wattage for bathroom
In the bathroom, only 12-16w lights are enough.
If possible, you can design two buttons: one is a cool color light, and the other is a warm color light and the wattage is not very high. This prevents eye discomfort caused by the bright lights at night and also drives away drowsiness.
Because bathrooms and toilets are a space with humid internal air, it is best to choose lamps with good waterproof performance.
5. Lighting wattage for bedroom
The lighting settings should be mainly soft, which can help people quickly enter a sleep state, and the wattage of the lamp needs to be lower.
If you have the habit of waking up at night, you can install a hidden light strip at the bottom of the cabinet and bed, so that you can see under soft light, so that it can illuminate the ground without disturbing your partner.
Bedroom area and relative lighting wattage: 5-10㎡，13-25W； 10-15㎡，25-38W； 15-20㎡，38-50W； >20㎡，>50W.
6. Children's bedroom
Children are in the developmental stage, their eyes are very sensitive to light, but they like to look at bright light sources very much, which is not good for the eyes; therefore, all light sources should be avoided as far as possible. The easiest way is to use a ceiling lamp, and then arrange an eye-protecting desk lamp is fine.
Children's bedroom area and relative lighting wattage: 5-10㎡，13-25W； 10-15㎡，25-38W； 15-20㎡，38-50W； >20㎡，>50W.
7. Elders' room
Unlike children, elderly people need brighter lights to see clearly due to their aging eyesight. Therefore, it should be calculated according to 5~8W per square meter, or a higher standard.
If you can't figure it out, it's best to ask the opinion of the aged. If it's not too bright, you have to buy a larger wattage.
The elderly room must be equipped with night lights, and the sensor light strips or sensor wall lights under the bed are very good.
Elders' bedroom area and relative lighting wattage: 5-10㎡，25-50W； 10-15㎡，50-75W； 15-20㎡，75-100W； >20㎡，>100W.
Because stairs are the connection between two floors, it is recommended to lay out lighting along stairs, wall light, or strip light.
After knowing the wattage requirements for different rooms, it will be easier to buy related lamps for your home.
