Wireless Dimmers Technologies: How to Choose the Right One

Dimmers for Lighting Control

Dimmers are devices that allow you to adjust the light intensity of installed fixtures. This enables you to tailor the lighting to your preferences, needs, and activities. These devices connect to your fixtures through your home’s existing wiring and can be controlled using wireless technologies, meaning you don’t need to do any construction. In some cases, an additional (neutral) wire may need to be installed using the already installed tubing.

Wireless dimmers offer many benefits for lighting control. In this article, we will explain how they work, what types of fixtures are compatible, how they connect, and the advantages they offer. We’ll also show you how Schallertech can help you install and set up a lighting control system based on the wireless dimmers that best suit your space and budget.

How Do Wireless Dimmers Work?

Wireless dimmers operate based on the principle of Pulse Width Modulation (PWM). This means they send electrical pulses to the fixtures to vary the time they are on or off. This adjusts the intensity of the light they emit.

Wireless dimmers can use various types of technologies to communicate with the fixtures. Some of the most common are Zigbee, Z-Wave, and WiFi. Each has its own characteristics, pros, and cons.

Zigbee

Zigbee is a wireless communication protocol that uses low-power, high-frequency radio waves. Zigbee is known for creating a mesh network among connected devices, meaning each one can act as a signal repeater. This results in greater coverage and reliability.

Zigbee has several advantages for lighting control. For example:

• It is compatible with many smart devices from various brands and manufacturers.
• It has low energy consumption and long battery life.
• It offers high security and data encryption.
• It allows the control of up to 65,000 devices on a single network.

Zigbee also has some disadvantages. For example:

• Requires a hub or bridge to connect to the internet and control devices through a mobile app or a virtual assistant.
• Can interfere with other WiFi networks that use the same frequency (2.4 GHz).

Z-Wave

Z-Wave is another wireless communication protocol that also uses low-power radio waves. Z-Wave also creates a mesh network among connected devices but operates on a different frequency than Zigbee (868 MHz in Europe and 908 MHz in America).

Z-Wave has some similar advantages to Zigbee. For example:

• It is compatible with many smart devices from various brands and manufacturers.
• Has low energy consumption and long battery life.
• Offers high security and data encryption.
• Allows control of up to 232 devices on a single network.

Z-Wave also has some disadvantages. For example:

• Requires a hub or bridge to connect to the internet and control devices through a mobile app or a virtual assistant.
• Has a shorter range and slower speed than Zigbee.

WiFi

WiFi is the most well-known and widely-used technology for wireless communication. WiFi uses high-power and high-frequency radio waves (2.4 GHz or 5 GHz) to transmit data between devices connected to a local network or the internet.

WiFi has some advantages for lighting control. For example:

• Does not require a hub or bridge to connect to the internet and control devices via a mobile app or voice assistant.
• Has greater coverage and speed than Zigbee or Z-Wave.
• Is compatible with many smart devices from various brands and manufacturers.

WiFi also has some disadvantages. For example:

• Has higher energy consumption.
• Can interfere or be affected by other WiFi networks using the same frequency.

What types of light fixtures are compatible with dimmers?

Not all light fixtures are compatible with dimmers. To be controlled by these devices, light fixtures must have certain characteristics, such as the type of power supply, voltage, wattage, etc.

The most common types of light fixtures that can be used with wireless dimmers are LEDs, halogens, and fluorescents. Each has its own particularities, benefits, and drawbacks.

LED Light Fixtures

LED light fixtures are the most popular and recommended for lighting control. LEDs are light-emitting diodes that illuminate when an electric current passes through them. LEDs have many advantages in terms of energy efficiency and light quality. For example:

• Consume up to 80% less energy than traditional light fixtures.
• Have a very long lifespan (up to 50,000 hours).
• Do not generate heat or emit ultraviolet or infrared radiation.
• Offer a wide variety of colors and light temperatures.

To regulate LED light fixtures with dimmers, it is necessary that they be dimmable. This means they have an integrated circuit that allows the light output to vary based on the voltage received. Not all LEDs are dimmable, so it is important to check before purchasing or installing them.

Usually, dimmable light fixtures announce it on their packaging.

It is also necessary that the type of dimmer is compatible with the type of LED. There are two main types: leading-edge dimmers and trailing-edge dimmers. The former are cheaper and simpler but can cause flickering or noise in LEDs. The latter are more expensive and complex but offer better performance and quality in LEDs.

Halogen Light Fixtures

Halogen light fixtures use an incandescent filament surrounded by a halogen gas (such as bromine or iodine). Halogens have some advantages in terms of light quality. For example:

• They offer bright and natural light (with a high color rendering index).
• They have good dimming responsiveness (can be regulated from 100% to 0% without losing quality).

However, halogens also have many drawbacks in terms of consumption and heat. For example:

• They consume up to 90% more energy than LEDs.
• They have a very short lifespan (up to 2,000 hours).
• They generate a lot of heat (can reach up to 300°C), which can be dangerous or uncomfortable.
• They emit ultraviolet and infrared radiation (which can damage objects or skin).

To control halogen light fixtures with wireless dimmers, it is necessary that they are compatible with the dimmer’s type of voltage. There are two main types: AC dimmers or alternating current, and DC dimmers or direct current. The former are more common and easier to install, but can cause flickering or noise in halogens. The latter are rarer and more difficult to install, but offer better performance and quality in halogens.

Fluorescent Light Fixtures

Fluorescent light fixtures use a tube filled with gas (such as argon or mercury) that illuminates when an electric current passes through it. Fluorescents have some advantages in terms of energy efficiency and durability. For example:

• They consume up to 70% less energy than halogens.
• They have an average lifespan (up to 10,000 hours).
• They do not generate as much heat as halogens.

However, fluorescents also have many drawbacks in terms of light quality and dimming. For example:

• They offer cold and artificial light (with a low color rendering index).
• They have poor dimming responsiveness (they can lose quality, flicker, or make noise when regulated).
• They contain mercury (a toxic metal that can be harmful to the environment and health).

To control fluorescent light fixtures with wireless dimmers, it is necessary for them to have a ballast or an electronic driver that allows the light output to vary according to the voltage received. Not all fluorescents have this component, so it is important to check before purchasing or installing them.

It is also necessary for the type of dimmer to be compatible with the type of fluorescent. There are two main types: analog dimmers or by variable voltage signal, and digital dimmers or by specific control signal. The former are simpler and cheaper but can cause compatibility or performance issues in fluorescents. The latter are more sophisticated and expensive but offer greater accuracy and quality in fluorescents.

How are dimmers connected?

The installation and configuration process for dimmers depends on the type of technology they use and the type of light fixture they will control. However, there are some common elements needed to connect wireless dimmers. These are:

• A hub or bridge: it is a device that acts as the control center of the wireless network. It connects to the internet and allows communication with the dimmers and light fixtures via a mobile app or a virtual assistant. It is necessary for dimmers that use Zigbee or Z-Wave, but not for those using WiFi.
• A mobile app or virtual assistant: it is the means by which you can control the lighting from anywhere inside or outside the home or office. It allows you to create scenes, schedule times, adjust brightness or color, etc. It is necessary for all types of wireless dimmers.
• Pairing: it is the process by which a connection between the dimmers and compatible light fixtures is established. A specific protocol or code is used to identify and synchronize the devices.
