Use the recessed lighting calculator on this page to calculate the placement and spacing for general lighting in a room. Just select the layout, enter the room’s dimensions, and hit calculate. You can also use the calculator to determine the placement for recessed task lighting above a surface by using its dimensions rather than the entire room.

Luxiflux Area; Buy. Web-Based Interior Lighting Calculator. Luxiflux Zonal is a zonal cavity (lumen method) calculation tool allowing a potential customer to quickly estimate the light level (illuminance), number of luminaires, power density and lighting layout, for a simple rectangular space. Click the button above to try it out! The Area Tool will then optimize the spacing in the X direction in 30' (or 9m) steps, and to the maximum spacing in Y that meets the illuminance criteria. The solution is the arrangement that covers the largest area while maintaining the illuminance criteria. NOTE: Please choose proper unit of your room area to help us count led lights (Lux and watts calculation) required per square foot/meter/inch. This Lumen calculation formula is using predefined standard LUX Levels required for different room types. Result may defer according to spacing layout of led lights and position from wall. Use this calculator to determine either the size of the circle of light, how far away you should place the light, or which degree of lens you should use. Put in two of the values and then hit calculate to find the third value. Values can be in feet or meters, but both values must match. Area Lighting, an important aspect of outdoor lighting, is very effective for the following: Lighting wide open areas such as construction sites, railway marshalling yards, ship yards, docks, airport aprons, parking areas and filling stations.

Note: You can actually use any format with the calculator – inches, centimetres, or feet. I recommend using inches or centimetres rather than feet because it is more precise.

Obviously this calculator does not cover all of the possible room shapes, layouts, or quantity of recessed lights a room may need. However, it should give you an idea of how to apply the formula for the placement and spacing of recessed lighting.

If you’re unsure where to begin, you can also use our general lighting calculator to help you determine how many recessed lights the room needs.
