Frequently asked questions
Short answers to the questions we get most often. If yours is not here, send an inquiry — we answer directly.
Buying and inquiries
Can I buy a product directly on this site?
No. This is a catalog, not a webshop. You pick the product here and send an inquiry; we then connect you with the nearest authorised partner or come back to you with an offer.
Send an inquiryHow do I get a price?
Send an inquiry with the product code and the quantity. For larger quantities and projects we agree the price through the partner programme.
Wholesale and projectsWhere can I see a product in person?
At our authorised partners. The store locator lets you search partners by city and see which ones are closest to you.
Where to buyHow quickly do you answer an inquiry?
We process inquiries on working days. An inquiry sent outside business hours is answered on the next working day.
ContactProducts and choosing
How do I choose the light colour?
Light colour is measured in kelvin. Warm white (2700–3000 K) suits living rooms and bedrooms, neutral white (4000 K) suits kitchens, bathrooms and offices, and cool white (5000–6500 K) suits workshops and industrial spaces.
Advice and guidesWhat does the IP rating mean?
The IP rating says how well a luminaire is protected against dust and water. In a bathroom the installation zone decides the rating you need; outdoors you need a higher level of water protection.
Advice and guidesHow do I know what capacity of air conditioner I need?
The capacity depends on the room area and height, insulation, sun orientation and how many people use it. Send us the room details through an inquiry and we will propose a size.
Send an inquiryWhere are the technical data and manuals?
The specifications sit on each product page. Catalogs, datasheets and manuals are on the documentation page, where you can search and filter them.
