We should consider the relationship between living space and lighting. Soft and bright lights depend on the cooperation of lampshades and bulbs. The brightness of the bulb affects people's visual function, vision maintenance and physical and mental health. Secondly, considering the room space and lighting brightness, too large power lamp waste electricity, easy to heat, may cause all kinds of incidents; choose too small power, and can not achieve better lighting effect.




一般卫生间的照明每平方米2瓦就可以了;餐厅和厨房每平方米3瓦足够了，而书房和客厅要大些，每平方米需4瓦;在写字台和床头柜上的台灯可用15至60瓦的灯泡，最好不要超越60瓦。卧室用40到50W左右就可以了，书房40W，客厅60W到80W，卫生间20W左右，厨房30W。以上也不是绝对的，跟个人喜爱也有联系，只需自己绝对适宜就行。


General toilet lighting per square metre of 2 Watt is OK; dining room and kitchen per square metre of 3 Watt is enough, and the study and living room is larger, 4 watt per square metre; desk lamp on desk and bedside table can use 15 to 60 watt bulb, had better not exceed 60 watt. Bedroom 40 to 50W or so can be, study 40W, living room 60W to 80W, toilet 20W or so, kitchen 30W. The above is not absolute. It is also related to personal love.
