You will need two light bulbs (800 lumens each) to illuminate the whole kitchen and additional 7 LED lights (200 lumens each) above the counter.HOME | LD ASSISTANT | GALLERY | SUPPORT | Let's assume you're using a standard bulb that emits 800 lumens for the kitchen and small LED lights that emit 200 lumens each above the counter.ĭivide the total number of lumens by the efficiency of the bulb and round up to figure out the number of bulbs you need: Then, choose the type of a light bulb you want to use. Multiply the required illumination level by the area to figure out how many lumens you need:.The counter is 4 meters long and 60 cm wide: The whole kitchen is a rectangle of length 4 m and width 2.5 m, so you can calculate the area as For the whole kitchen, it is 108 lux, and for the counter (detailed tasks) - 538 lux.ĭetermine the dimensions of your illuminated space.

You can use illumination units of lux or foot candles. Once you know all these values, the foot candle calculator will determine how many lumens you need in total. If you're trying to figure out LED lighting for your kitchen counter, the illuminated area will be calculated as the length of the counter multiplied by its width. In the case of a bedroom or a bathroom, it will simply be the total area of the room. The next thing you need to determine is the illuminated area. Intuitively, ambient light in the bedroom shouldn't affect our preparations to sleep time and won't be as intensive as the light required for sewing.
Simply select one of the options from the list, and our lighting calculator will automatically determine the optimal level of illumination in lux or foot candles (that is, how much light should be incident on the surface). In the first step of your calculations, you need to choose the type of area and activity that you want to illuminate.
