What is the RGB Easy+ system?

The RGB control system is a LEDS C4 system. It requires master controllers and slave controllers with push buttons and/or a remote control. The system includes a memory function to store the most recently assigned programme and/or colour. The 71-E069 master controller has a push button and remote control and the 71-E011 master controller has a push button without remote control. The 71-E070 slave controller is only suitable for our products with electronics designed for control with EASY RGB+ protocol. 

The products available with the RGB Easy+ system are Cube RGB Easy+, Aqua Spotlight AISI 316 RGB Easy+ and Gea Easy+. 

Download the EASY RGB+ system manual for detailed information about how to connect the product, distances and cabling sections to use, how to synchronise the remote control with the master controller, a description of the buttons on the remote, its reach and the type of batteries it uses.

How can I install outdoor recessed uplights?

We recommend following the instruction in this video for installing any of our outdoor recessed uplights.

What is the Play series configurator?

It helps configure the code for the chosen composition. It allows you to configure your PLAY product, using a large variety of available frames, LED modules, accessories and finishes. Click here to configure yours.

What is the Casambi system? What are the Casambi modules and what are they for?

It is a control system based on Bluetooth technology that can be directly controlled from a smartphone or tablet without having to change the existing installation. A scalable solution from one to several lines of lights, with point-to-point control or centralised control. To turn a conventional light into a light controlled using CASAMBI, the product must be dimmable, and a small module will need to be added either inside or outside the product and this will have to be bought separately. 

We have two different modules to choose from depending on the product protocol or dimming control:

  • Module 71-5961 for products with 0-10V dimming and DALI control.
  • Module 71-5959 for dimmable products with short phase trailing edge protocol. 

If the product can be dimmed, LEDS C4 will include the dimming protocol for the product in the general catalogue, on the website and technical sheets. 

What maintenance does stainless steel need?

Although stainless steel as a material is resistant to corrosion, we recommend planning regular maintenance and cleaning to extend its corrosion resistance and good appearance for many years. The frequency of this maintenance will depend on the environmental conditions where the piece is installed. For products installed at the seaside and in indoor pools we recommend more frequent cleaning. We particularly recommend cleaning to remove surface residue that may contain damaging substances and that may cause corrosion from scratches, lime and chloride. We recommend using specific products to clean stainless steel, water, nylon brushes and rinsing well with water.

What are MacAdam Steps? And how are they related to light quality?

With the introduction of LED technology, it is easy to find LED products installed in the same location but with notable differences in colour tone, which are easy-to-maintain but do not create a space with a comfortable feel. This is why it is necessary to use a system to control the colour, for example in clothing stores where fabrics can seem to be different colours depending on the light quality.

MacAdam ellipses were created by Dr David McAdam in 1942 and make it possible to acquire LEDS that represent regions on a chromaticity diagram containing colours the human eye cannot distinguish between.

The MacAdam “steps” are groups of LEDs in small or large chromatic regions which guarantee they have similar characteristics. The smaller the steps of the smaller the difference in colour and the higher the price. How many steps you need depends on how you plan to use the product. Currently products which require higher light quality should use LEDs with at least three MacAdam steps.

What is UGR?

UGR is an index developed by the International Commission on Illumination and establishes direct glare depending on the position of lights, the features of the environment and the position of those operating the light.

UGR values range from 10 to 30. The lower the number, the less glare is produced. European lighting regulations require a UGR rating for each use.

UGR information is presented in tables, two values are taken for each observation position; a longitudinal value and a transverse value. These two values are determined depending on the reflections from the ceiling, walls and floor, the height of installation and the transverse and longitudinal position of the operator in the space.

What is the difference between fans with AC or DC motors?

Our brand offers fans with two types of motor, AC and DC. DC fans are quieter than AC fans, more efficient in energy terms, they weigh less and offer greater control in terms of speed (fans with DC motors have five speeds compared to the three speeds offered by AC motors). They also have a longer useful life and are multivoltage. 

Can fans be installed on sloping ceilings?

Most of our fans can be installed on sloping ceilings with slopes of up to 15°, except for the Stem, Garbí, Fus, Formentera and Rodas models. 

How can I synchronise the remote with the fan receiver?

We have three different types of remote control depending on the model of fan. The technical manual for each fan provides specific information about the remote control included with each fan, click here.

What is the recommended height to install a ceiling fan? What diameter fan is recommended for each room?

We recommend installing the fans 2.3 m from the floor as this is the height the blades should be installed at.

Depending on the size of the room we recommend different sized fans. As a guide, we recommend using fans with the following diameters:

  • Up to 110 cm for rooms of up to 15 m²
  • Up to 150 cm for rooms between 15 m² and 30 m²
  • Larger than 200 cm for areas over 30 m²
What is the winter or inverse setting and the summer setting? Where is this setting on our fans?

The fans have a feature to change the direction in which the blades turn. On the summer setting, warm air is directed to the upper part of the space, on the winter setting the warm air is directed downwards.

The fans with AC motors have a switch just above the blades next to the motor.

For the fans with DC motors, the direction the blades turn can be changed using the remote control.

What will I find in the fans technical manual?

Download our general guide for fans to check our full list of fans, the type of remote control that each fan uses, available accessories, wiring diagrams for controlling the fan using a remote control, a wall switch, a chain or controller fixed to the wall. You will also find information about how to reduce vibrations from the fans and synchronise different fans using one remote control. Click here.

Are all models of fans compatible with the fixed wall controller? How many fans can be controlled with one controller?

The fixed wall controller is only available for fans with AC motors. We have two types of wall controllers: with switch (71-4932) or without switch (71-4933), depending on whether the fan has a light or not.

Each controller can only be used for one fan.
