Recessed ceiling spotlights/downlights are available in many different versions. These parameters primarily define this product family: 
  • Hole diameter - We recommend selecting the spots first, then drilling the holes. Otherwise the limitation is predetermined Output 
  • Light output in lumens, or wattage. How much light is needed in the room. There is no general answer to this question. Use the following link for the project enquiry 
  • Installation depth - usually a mandatory requirement in terms of drill hole depth or distance from suspended ceiling. 
  • Color temperature dimmability - We recommend modern options such as DALI or Casambi. 
  • Beam angle - For uniform room illumination. Usually determined by the distribution of the spots in the room and the room height. 
  • Fastening - Installation in false ceiling or concrete ceiling Glare - Depending on the viewing angle, lower LEDs in the spotlight can often no longer be perceived as a bright point of light, thus ensuring pleasant lighting.

If you have a lighting project and would like to use downlights, please use the link provided for our project enquiry form. We will try to answer all your questions.

It is a challenging topic. A basic distinction can be made between these types of LED luminaires: 
  • designer luminaires (the eye pays the price regardless of the technical design) 
  • luminaires with replaceable LED light sources (less sustainable) 
  • luminaires with permanently integrated LED boards and their own LED driver (most sustainable solution with the best efficiency and flexible options for dimming via DALI, 1-10V, etc.) 
  • technical luminaires with special lighting tasks such as LED downlights.

Colloquially, they are often equated with each other. However, lighting experts make a clear distinction between lamps and luminaires.

This also applies to LEDs. A lamp is the typical light source (e.g. a light bulb) that is screwed into the socket of a luminaire. That already explains it. Luminaire is the system consisting of lamp, base, lampshade, etc. LED luminaires are available with a replaceable LED light source (lamp) and with a permanently installed LED module. The advantages and disadvantages can be found in another FAQ.
