Fluorescent Light Lux Level

You can calculate lux from watts luminous efficacy and surface area.

Fluorescent light lux level.

The same 1 000 lumens spread out over ten square metres produces an illuminance level of only 100 lux. The illuminance e v in lux lx is equal to 10 76391 times the power p in watts w times the luminous efficacy η in lumens per watt lm w divided by the surface area a in square feet ft 2. E v lx 10 76391 p w η lm w a ft 2 watts to lux calculation with area in square meters. Thus lighting a larger area to the same level of lux requires a greater number of lumens.

Lighting larger areas to the same necessary lux levels will requires a larger measured level of lumens this is usually achieved by increasing the number of light fixtures and hence the power consumed. Achieving an illuminance of 500 lux might be possible in a home kitchen with a single fluorescent light fixture with an output of 12 000 lumens. How to convert watts to lux. Watt and lux units represent different quantities so you can t convert watts to lux.

To light a factory floor with dozens of times the area of the kitchen would require dozens of such fixtures. How to convert electric power in watts w to illuminance in lux lx. The amount of light that is cast on a surface is called illuminance which is measured in lux this can be thought of as light intensity within a specific area. Let s say you re planning the lighting for your kitchen including the kitchen counter.

For the whole kitchen it is 108 lux and for the counter detailed tasks 538 lux. Choose the area of the house that you want to illuminate. Watts to lux calculation with area in square feet. Check the optimal lighting level.
