How many downlights should I use to light a room?
This one of the most frequently asked questions, and one that does not have a standard answer. The light level and coverage varies greatly with room usage. For general lighting applications a good rule of thumb is to space fixtures not more than half the ceiling height. For example if a room has an 8’ ceiling you would not exceed 4’ between fixtures. This ensures even coverage but may be far more than a den needs and less than a reading area or work station needs. Use this principle as a base line.
