Let's plan lights for your room

Do you know how to calculate lights for your room?
I'll teach you in few seconds. First of all you need to check the squire feet of room. you should place minimum light in bedroom, a little more in living room, little more in kitchen and you should use maximum light in office room.
If you have 100Sq.ft bedroom you need to use 2000 lumens light and if you have 100Sq.ftliving room you need to use 3000 lumens light and if you have 100Sq.kitchen than you need to use 4000 lumens light.
