What is the function of dimmers?
Dimmer varies the intensity of light emitted from an electric lamp and provides the flexibility to vary the amount of light in a given space, depending on the individual requirements, tasks or activities being performed.
What is a Universal Dimmer?
Universal Dimmers are designed to control incandescent, dimmable LED and dimmable CFL bulbs. They offer full-range dimming, smooth start-up, and eliminate flickering and fluttering of lights.
Why should I consider using a dimmer?
Dimmers provide three basic benefits. They create ambiance by giving the user the ability to adjust light levels appropriate to the activity, they reduce energy consumption for greener living and, based upon reduced energy consumption, help lower electric bills.
Does dimming the lights save energy?
Light dimmers save energy by reducing the flow of electricity to the bulb and allowing lights to operate with lower power outputs. Since lights under less stress shine longer, dimmers are known to extend the life span of your bulbs, too.
Where can dimmers be used?
Dimmers can be used to control lighting almost anywhere in a commercial building or residence: Commercial uses include hotel and hospitality, ballrooms, conference room, auditorium, cinema, health care, places of worship, restaurants, retail, office and other commercial spaces. Residential uses include living, dining and entertainment areas, bedrooms and bathrooms, kitchens and utility areas, family and game rooms, dens, home theater, hallways and exterior/ landscape/pool lighting.
Are all LED lamps dimmable?
If an LED is not listed as dimmable, it usually will not be. To be able to dim an LED, you must purchase one specifically designed for dimming. If an LED is dimmable, it will be listed on the packaging of the LED and possibly on the lamp base. Please contact the manufacturer to be sure.
How do I know what type of dimmer to buy?
You can select a dimmer based upon the electronic standard that your country uses, now we provide Australian, European, England, America standard and South Africa. Besides, it depends the fixture or the type of light source you wish to control. Dimmer switches are generally used for ceiling mounted fixtures. They come in a variety of styles including traditional rotary ,push button, bell door push and contemporary slide models.
What kind of dimming range can I expect?
Dimming range will depend on both the bulb and the control. Many LED bulbs are not capable of being dimmed below a 10% measured light level, regardless of the control used.
What LED lamps are compatible with your dimmers?
Our dimmers are compatible with most of the Mainstream LED lamp brands. If you are not sure, we can send some samples for you to test or you can send your light to us, we are glad to test it for you.
What are intelligent dimmers?
Intelligent dimmers include features that standard dimmers usually will not. They are in place to extend the life of the lamps and the dimmer by protecting against overloads and spikes in the circuit. The features include soft start and overload protection. All series dimmer we made are intelligent dimmers.
What is memory function feature?
During a loss of power, the system should retain all the programming information in internal memory (for up to 10 years). When power is restored, the system will automatically return all settings to their last state before power was lost. The system data should be stored in a secure removable memory module (EEprom or Flash) so that in the event of a system failure it can be simply exchanged without the need to reprogram the system.
What is the soft start feature?
When the dimmer is turned on, it will slowly bring the lights to the set level over a period of around a second. This is designed to extend the life of both the lamps and the dimmer but preventing any spikes on start up.
What is overload protection?
Our dimmers have an overload protection feature. This feature will work in different ways for each different dimmer. Overload protection mode will kick in if you mistakenly connect your dimmer to too many lights or transformers. It will protect itself from failure by turning the lights down or off until the load is corrected.
Does it have over-temperature protection?
To combat overloading or insufficient de-rating, a good dimmer will automatically reduce lamp brightness when the dimmer is getting too hot. Then once the dimmer has cooled down, it will automatically resume normal operation. This is an excellent safety feature and it’s good to explain this to homeowners.
Does it have short-circuit protection?
Like all quality electrical accessories, you want a dimmer with short circuit protection. If the dimmer receives a short circuit or surge due to faulty wiring or lamp failure, you want it to automatically turn off before damage can occur. Again, this is a feature that’s great to explain to homeowners so they feel secure and know what’s happening, as well as what to do if the lamp goes off.
How do I choose between trailing edge or leading edge?
In most dimming applications it is more desirable to use a trailing edge dimmer. Trailing edge technology ensures less EMI being generated in electronic transformers, is 100% silent, usually reduces or even completely eliminates high inrush currents into lamps or the electronics of the lamps, is generally capable of handling a larger maximum load (due to the lack of inrush current mentioned) and is in general more compatible with a majority of load types, including electronic transformers. There are however some applications or lamp types (especially some LED lamps) which specifically requires a leading edge dimming solution.
How do I know the size of dimmer I need?
To calculate, simply multiply the wattage of each lamp by the number of lamps. This gives the total wattage on that circuit. The dimmer should match or exceed that wattage per circuit (dimmer channel).
Should a non-dimmable CFL be used with a dimmer?
No. A CFL that is not specifically designed for dimming should not be used on a dimmer. The CFL may flash or flicker and the reliability of the CFL or the dimmer may be reduced.
Can I use dimmable CFL and LED bulbs on the same dimmer at the same time? What about using dimmable CFL, LED, and incandescent or halogen bulbs on the same dimmer?
Maybe. Use of different types of bulbs on the same dimmer is determined by the dimmer design, and not all dimmers will be approved for use with different loads. Contact us for details.
Can I use CFL bulbs from different manufacturers on the same dimmer?
Yes, but dimming performance may vary from bulb to bulb due to variations between manufacturers.
What is the difference between rated wattage vs. equivalent wattage?
Wattage is a measurement of power. Rated wattage is how much energy a bulb consumes. Equivalent wattage is often used by bulb manufacturers to give you an idea of the brightness of an LED or CFL compared to an incandescent. When figuring out how many bulbs can be used on a dimmer, it’s important to use the rated wattage, not the equivalent wattage.
What is the difference between triac, thyristor and alternistor dimmers?
Triacs and thyristors are similar components: A triac is essentially two thyristors combined in one package: Thyristors tend to be more expensive but more robust. Triacs have the advantage that they are less likely to ‘half wave’ on failure. Alternistors are a perfectly matched set of two thyristors (SCRs wired inverse parallel i.e. backto- back). This chip construction provides two electrically separate SCR structures, providing enhanced performance characteristics, and can be used with highly inductive loads – often used in motor drive applications.
What is the difference between single pole and 2-way applications?
Single pole means controlling one or more lighting fixtures from one location. 3-way is the ability to control one or more lighting fixtures from two separate switch locations. An example of a 3-way is the ability to control the same fixture from a switch at the top of a staircase and from another switch at the bottom of the staircase.
Question: Can I use the dimmer in the outdoor area (covered terrace)?
Answer: The dimmer has the degree of protection IP20. The zero means that there is no protection against water, so the dimmer can only be used indoors.
Question: Dimmer does not control, but the light can not be switched off. What did I do wrong?
Answer: Verified inputs and outputs. In the manual, the phase (L1) and the lamp are connected. Do not connect the ground, the dimmer will get over the lamp. And check what was connected. Is the lamp really dimmable? If everything is done correctly, the dimmer is defective. Mine smoked after two seconds of operation.
What is multiway control dimmer?
Traditional one way or two way control dimmer only allows you to dim and switch on/off the light in one location or switch on/off in two locations but only dim in one location. Multiway control dimmer solves this problem which enables you dim as well as switch light from any wall plate location, without additional wiring or control system.
What is 1 way, 2 way and multi-way ?
The one way switch means only one switch to controls one or one group illuminant device; The tow way switch means two switches which control one or one group illuminant device in different positions; The multi-way switch means switches which control one or one group illuminant device in three or more positions.

How do I know if the USB Charger Devices are charging my electronic device?
When an electronic device is plugged into the USB Charger, the device will indicate that it is charging. If your device is not indicating a charge, it may have high charging requirements. If using the 1.5A or 3.1 A USB Charger/Tamper-Resistant Outlet, switch the device to the high power port on the right to maximize its charging ability. Devices with a high current charging requirement, such as tablets, may still charge in the standard power port (left port), but will not charge at its maximum current and may not indicate a charge. Be sure to connect higher current devices to the high power port.
How long will it take my electronic device(s) to charge?
Due to different battery types and charging requirements, the charging time may vary from device to device.
Can I charge multiple tablets at once?
Yes. You can charge one tablet using the high power USB port (right side) and charge a second tablet using the Tamper-Resistant Outlet. For the safety of the devices, the charger will shut down if two high power devices are plugged into the USB ports at the same time.
What charging capacity does the socket provide?
The USB wall charger provides a total of 2.1A charging capacity. This means that if only one device is connected, the total rated output current of 2.1 A is available from either port. In the event that both ports are connected, the total rated current will be divided between the two ports. It detects differing charging configurations and requirements and reacts accordingly, for example if two devices were charging simultaneously, more current will be diverted to the device with the least charge and the biggest demand.
What happens if I mix and match a USB charger cable with a USB plug?
