How many watts of ceiling light does a 10 square meter bedroom require?
So even if the number of tiles, as long as the flux or temperature is not the same, so the illumination of the lamp is not the same.
Warm white light: also called middle color, its color temperature is between 3300K - 5300K;
Luminous efficiency = luminous flux / electric power (unit lm/w); illuminance = luminous flux / area (unit LX).
This is not just watch watts, but also depends on luminous flux and color temperature of lamps.
