How many LIFX bulbs do I need to light my room or house?

The number of bulbs needed for a room or house varies depending on your how bright you want a room to be. Below is a rough guide for fitting out your whole house or a room with LIFX bulbs.
Determine square footage of the room
Multiply the Length times the Width of the Room to get the square footage of the room. For example, if the room is 10 feet wide and 10 feet long, the square footage of the room will be 100 square feet.
Determine the foot-candles by room type or room purpose
A foot-candle is how bright the light is one foot away from the source. Lighting needs vary, depending on the type of room being lit and on your personal preferences. We have included a general guide for common rooms below. Example: a bathroom or kitchen will need more foot-candles than a living room or bedroom.

Room Foot-Candles suggested

Living Room 20-30
Kitchen 40-60
Dining Room 30-40
Bedroom 20-30
Bathroom 40-60
Hallway 10-20


Determine the Lumens needed to light the room

A lumen is a unit of measurement of light. LIFX bulbs provide different lumens depending on model. They are dimmable, so you can use more of them at a lower brightness if that's what your room needs.

 Multiply the square footage of your room, by the foot-candle rule in the table above. This will tell you how many bulbs in general, you need for use in a room. For a 100 square foot living room, you need 20-30 foot-candles. That would be 2,000-3,000 lumens, or 2-3 LIFX A19 lights, or possibly 3-4 LIFX Mini lights. There is always the option to add more or have less lights in the room, for your own personal taste.
