In the first step of your calculations, you need to choose the type of area and activity that you want to illuminate. 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. Intuitively, ambient light in the bedroom shouldn't affect our preparations for sleep time and won't be as intensive as the light required for sewing. The next thing you need to determine is the illuminated area.

In the case of a bedroom or a bathroom, it will simply be the room's total area. 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. Once you know all these values, the foot-candle calculator will determine how many lumens you need. We use the following equation:. You can use illumination units of lux or foot candles. If you want to recalculate between these units, remember that one foot-candle equals Also, check out our lumens to watts calculator if you're curious about how many lumens various light bulbs produce under a given wattage.

Once you know how many lumens you need, you can start figuring out how many light bulbs will suffice to illuminate your surface. To do it, use the formula below:. BL stands for the number of lumens that a light bulb emits. You can usually find this number on the bulb packaging. It's a much better indicator of the bulb's luminosity than the wattage, as LED lights often need less power than regular light bulbs. Choose the area of the house that you want to illuminate. Let's say you're planning the lighting for your kitchen, including the kitchen counter. Check the optimal lighting level. Determine the dimensions of your illuminated space. The whole kitchen is a rectangle of length 4 m and width 2. Then, choose the type of a light bulb you want to use.

Let's assume you're using a standard bulb that emits lumens for the kitchen and small LED lights that emit lumens each above the counter. Divide the total number of lumens by the efficiency of the bulb and round up to figure out the number of bulbs you need:. You will need two light bulbs lumens each to illuminate the whole kitchen and additional 7 LED lights lumens each above the counter. If you're wondering how much you'll pay for electricity when using all of this lighting, take a look at the electricity cost calculator! The lux is a measurement of the received light per area unit.

The lumens is a unit that measures the amount of light emitted by a light source. If you plan to use lightbulbs with an intensity of lm , you'll need five of them. The lumen is a unit of luminous flux; lumens correspond to the amount of light emitted by a source as a lightbulb or a candle, regardless of direction. Lux is used to measure the amount of light shining on a surface. A high amount of lux corresponds to a brightly lit surface. Embed Share via. Lighting Calculator Created by Bogna Szyk.
