Illuminating a room properly is a task that often seems easier than it actually is. The lighting must be bright enough, but must not dazzle or damage the eyes. It should save energy and costs, but must provide sufficient light for the respective activities in the room - especially in the business area. Companies often even have to adhere to lighting guidelines in order to comply with occupational safety regulations.
In your private life, you can decide much more freely about your preferred room lighting in your home. However, it is also recommended here to inform yourself beforehand about the proper exposure in order to avoid unintentionally investing a lot of money in unsuitable lamps.
On this page you will find answers to popular questions before purchasing LED lamps. We will be happy to help you find the perfect light sources for your particular space!
If you are still new to the subject, we advise you to also have a look at our encyclopedia of light page.
How many LED lamps do I need?
There are a number of factors that influence the lux values (illuminance on an area) and lumen values (luminous flux from a source) and that ultimately determine how many LED light sources you need.
- The height of the ceiling: A high ceiling means less light on the floor and thus a lower lux value. 1 lux corresponds to 1 lumen/m2.
- Windows: If a lot of outside light enters the room, less artificial lighting is needed during the day. This does not apply in the evening/at night, but should be taken into account during the day (e.g. in offices).
- The colour of the ceiling, walls and floor: a white room reflects much more light than a dark room. In a brighter room, therefore, fewer light sources are required.
