Frequently Asked Questions (FAQ)
Are all your LED products dimmable?
As technology advances, so do the conditions. Nowadays it is hardly ever necessary to wonder whether or not the products are dimmable.
All of our indoor products are dimmable.
Our HP and COB diodes are controlled on the primary side of our dimmable drivers.
Our SMD diodes (frequently used on LED strips) are controlled secondarily, in other words; you receive a 12-24 V DC dimmer and place it following the driver, adjacent to the load.
The only products where dimmability cannot be taken for granted are the ones intended for outdoor use. The vast majority of the in-ground and landscape fixtures, as well as the deck lights are primarily designed for effect lighting. This is why it has been considered unnecessary for these fixtures to be dimmable.
If you are unsure whether or not a product is dimmable, please check the symbols associated with the product.
What type of cable should I use, and what length is appropriate?
Upon installation of our LED products, a multithread 0.75 mm two-wire cable is preferably used. The most commonly used one is RKUB but any kind of multithread cable will do (RK/MK).
We recommend that the total length of wiring when installing constant current diodes (350/500/700 mA) should be a maximum of 30 m. Increasing the thickness of the conductors will raise the conductive capacity and the length of wiring can thus be increased, provided it is still a multithread cable.
Do I have to use safety boxes when mounting LED down lights?
When installing LED fixtures in insulated spaces, a safety box is always required. If you consider the air space in between the vapor barrier and the flush mounted surface to be sufficient enough to waive this requirement, that is a decision that should ultimately be supported by the electrician.
The general distance we recommend in between our recessed products and non-combustible material is 30 mm (at the top).
Exempt are our mini down lights which naturally require much less of an air space at the top and the LED FOR WORKERS products that are mounted directly into the socket.
What dimmers are suitable for use in conjunction with your LED products?
Our drivers are adapted for both leading and trailing-edge control. Dimmers we have tested toward our products and recommend.
Do you have a dimmer of a different type or make? Contact the manufacturer and let them know that you wish to dim an LED load of 350/500/700 mA alt. 12/24 V DC.
You could also refer to the dimmers we already recommend and see if they have anything technically equivalent to those.
Is there any driver available for DIN mounting?
Absolutely, Designlight is proud to offer a driver that very easily can be mounted onto the DIN bar in your switchbox.
Now you can gather all the drivers where they belong, with the rest of the electrical equipment.
Upon coupling of multiple drivers, hardwire the 1-10 V connection.
What distance should I keep between my spotlights?
The preferable distance between walls and fixtures varies depending on the situation. When calculating the preferred distance, take into account:
- Ceiling height
- The technical data for the fixture itself (beam spread etc.)
- Degree of reflection on walls and floors.
Assuming there is a space with a regular ceiling height of 2400 mm, a light wall color, and a fairly light floor as well, it is possible to offer general recommendations regarding distances.
- Distance from walls: Ceiling height divided by four (2400/4=600mm).
- Distance between fixtures: 1200-1600 mm
For a correct placement of your fixtures, always contact a professional for a more detailed lighting proposal.
What kind of encapsulation requirements are placed on lighting in bathrooms and other wet rooms?
Previously, wet rooms have been divided into different zones from floor to ceiling and thus have had different encapsulation requirements depending on how far from the actual bath or shower they have been placed.
Nowadays, zone 3 is not only defined on a vertical plane but also on a horizontal plane.
As long as the ceiling height is more than 2.25 m, the ceiling will be considered a dry environment. This means that you could mount an adjustable IP21 fixture in a ceiling like that without any problems.
However, it is usually a good idea to install an IP44 classified fixture above showers since there is a possibility that a showerhead could be directed toward the ceiling.
If the ceiling height is less than 2.25 m, the IP classification must be adjusted to the applicable zone.
