The quantity is calculated from the illuminance target of the space type (EN 12464-1) and the product's power and lumen data. This is a preliminary design; we prepare a DIALux design for the final layout.
How is it calculated?
- Choosing the type of space fills in the EN 12464-1 illuminance target and maintenance factor.
- The lumen method is applied with the product's power and lumen data, the room size and ceiling height; the quantity is laid out evenly in columns × rows.
- With automatic power, the variant that keeps the spacing best suited to the mounting height is chosen. You can change the power and the layout yourself.
- The result is a preliminary design; we prepare a DIALux design for the final layout and light distribution.
Frequently asked questions
How many m² does a 600×600 LED panel light?
With a 500 lx office target, a 36 W, approx. 4,300 lm 600×600 panel lights about 5.5 m² at 3 m ceiling height. In 100 lx areas such as corridors it covers more than 15 m².
Is the quantity final?
It is a preliminary estimate. The lumen method gives the average illuminance; the exact distribution with furniture, columns and windows is confirmed in a DIALux calculation.
