Description of HDQ4S - 2G 1 or 2W 2x250W Dimmer Dimension Screwless Premium White

VARILIGHT® dimmer switches have an industry-wide reputation for exceptional performance, long life and innovation at attractive prices. Like all our products these dimmers are designed to meet the latest European Safety Legislation.


It is important to select the correct dimmer switch for your application so please read the following information carefully.



Our standard dimmers are recommended for mains voltage lighting only, although they can also be used on low voltage applications, but the Intelligent (IQ) Dimmer and Touch/Remote Dimmers are best suited for these applications.



The lights are dimmed by a rotary control knob and turned on and off by a push on/ push off action. Push on/ push off dimmers are suitable for 1-way and 2-way circuits.
When selecting a standard dimmer add up the wattages of the bulbs you wish to dim and choose a dimmer with a suitable maximum load rating. If you have a 2-way circuit (where the same lights are controlled by two switches) you must choose a push-on/push-off dimmer and replace one of the switches with that dimmer. You can only use one push-on/push-off dimmer in a 2-way circuit. It must be used in conjunction with a normal switch. When you switch on a push-on/off dimmer the lights will come on at the same level they were at before they were last switched off.



1 or 2 way Push on/push off dimmers can be used for mains incandescent GLS lamps (standard mains light bulbs), maximum load as specified on the dimmer. It can also dim GU10 or similar Hi Spot Mains Halogen lamps (only use quality UK supplied lamps) maximum load as specified on dimmer. [Please note by using Touch/Remote Dimmers there is a zero risk of damage in case of lamp failiure and a dramatically improved lamp life].



If you are using the dimmer with quality low voltage transformers such as VARILIGHT® low voltage transformers (product codes: yt70, yt105, yt150, yt250) you can control them up to maximum load as specified on the dimmer. If you are using other low voltage transformers, not made by VARILIGHT® we recommend only to control up to 5 low voltage transformers per circuit, as long as the total load does not exceed maximum wattage stated on the dimmer. [Noise levels may vary depending on type, quality and quantity of transformers used].



You are not able to use Rotary Push on/push off Dimmers on Wire Wound Transformers or fans and other Inductive Loads (for these products see Intelligent Dimmers, Touch/Remote Dimmers, and Fan Regulators).

YCA20D-E27 The NEW Varilight Dimmer Dimmable Energy Saving Lamp with Edison screwed Fitting
VARILIGHT Switch Dimmable EnergySaver+ Lamp. This new 20W T3 spiral Dimmable EnergySaver+ CFL, can be dimmed using a standard dimmer switch from 2.46% to 100% brightness and is predicted to save the purchaser more than £100 on energy bills, during its 16000 hour lifetime, compared with an equivalent 100W GLS lamp. Combining the energy-saving properties of a CFL with the capacity to dim results in superb energy efficiency calculated to reduce carbon emissions by more than half a tonne with every GLS lamp replaced.

This is the Varilight Dimmer Dimmable Energy Saving Lamp with Edison (Screwed) fitting, which you are able to run using a light dimmer. If you are looking to buy the bayonet version, the stock code is YCA20D-B22.

The dimmer dimmable lamp (YCA20D-B22 or YCA20D-E27) can be used with most dimmers, but for best results please use the Varilight touch/remote dimmer that has a minimum wattage of 20watts. With these dimmers you are able to dim just 1 lamp and up to 24 lamps depending on the maximum wattage of the touch/remote dimmer chosen.

This version is the Varilight Dimmer Dimmable Energy Saving Lamp with Edison (screwed) fitting. If you would prefer the Varilight Dimmer Dimmable Energy Saving Lamp with bayonet fitting, please choose YCA20D-B22.

The Dimmable Energy Saving Lamp produces an output of 1300 lumens. Further benefits are provided by the DigiFlux® digital dimming technology with excellent power factor correction delivering a power factor of over 0.95 for the Dimmable EnergySaver+. This compares with a power factor of less than 0.6 for most CFLs, which results in inefficient energy distribution and higher energy costs.

At a time when governments have energy-saving high on their agenda, and with energy costs soaring, we expect these new products to appeal to local authorities, industry and householders alike.

This light bulb is designed to be used with a standard domestic dimmer switch (with phase cut technology, leading or trailing edge). For optimum compatibility choose Varilight dimmer switches.

Check the loading limits of your dimmer: This energy saving light bulb is rated at 20W.
Please note that dimmer switches have minimum load limits. Therefore you must check the minimum load of your (usually on the rear of the dimmer or on the packaging) and make sure the minimum load is met. For example, if the dimmer has a minimum load of 40 watts (W) you need to use at least 2 Dimmable Energy saving light bulbs (2x20W = 40W).

Special Varilight low load dimmers are available with a minimum load of 20W if you want to use just one Dimmable Energy Saving lamp with a dimmer...Please look in the REMOTE DIMMERS Category, and choose any of these.

Also check the maximum load limit, so that if your dimmer has a maximum load limit of 250W then you can use a maximum of 12 Dimmable energy saving light bulbs (12 x 20W = 240W)



**Approximate values based on average usageThis dimmer dimmable energy saving lamp can be used with dimmers only, for the switch dimmable version please see YCA20S-E27.
