Energy Saving

Saving energy is good for the environment as well as your bank balance and, with modern lighting technology, is as easy as plugging in a new light bulb! Choosing an Energy Saving Lightbulb to replace your existing bulb has never been easier, please use our interactive calculator below or visit our Choosing Energy Savers section Here

    FAQ

    Compact Fluorescent (CFL) or LED?? We answer some of the most common questions about both technologies here…

    Do they flicker when you turn them on?

    CFL

    Unlike early energy saver lamps a few years ago, the latest designs include electronic rapid start circuitry to make the lamp light in less than 1 second with virtually no flickering.

    LED

    Never. The way that LEDs work means that they always switch cleanly on or off. If they flicker, there’s a problem with the circuits inside.

    Don’t they give a rather harsh light?

    CFL

    Some older designs had quite a high “colour temperature” see glossary which may be perceived as “colder” but many energy saving lamps now give off a “Warm White” light to make the light very similar to a normal incandescent bulb.

    LED

    Less reputable manufacturers will cut corners with their LEDs and often this will affect the colour of light they give out. Good quality LEDs give out light in either a fresh Daylight colour or much more commonly, a cosy Warm White colour - and they give a better representation of colour than CFLs.

    Do they take time to “warm up”?

    CFL

    The latest compact fluorescent lamps “warm up” very much faster than older designs, typically reaching 95% of their full light output in under a minute.

    LED

    None at all. LEDs light instantly at full brightness.

    They are always too long and stick out above my lampshade!

    CFL

    Again, with the latest designs, this need not happen. Many compact fluorescents are now so small that they are virtually the same size, or even smaller, than ordinary bulbs. If the bulb is visible, you can choose from one of the designs that uses a decorative outer bulb to cover the fluorescent tubes.

    LED

    LED technology is much more compact than CFL and the bulbs nearly always identical in shape and size.

    Do Enery Savers get hot?

    CFL

    Compact fluorescents are far more energy efficient than normal light bulbs so they give out far less heat, making them safer for use in unattended security or night light applications. This also makes them ideal for use with lampshades made of delicate materials that can be damaged by heat. All lamps do however give off some heat and should not be used in a totally enclosed light fitting unless there is some way for the heat to escape.

    LED

    Like CFL bulbs, LEDs run at much cooler temperatures than traditional bulbs. However, it is necessary to keep the chip inside the bulb as cool as possible. LED bulb bodies are therefore often made up of heat-sinks which can feel hot-to-touch after prolonged use.

    Can energy savers be used with a dimmer switch?

    Most compact fluorescent energy savers available on the UK market cannot be dimmed using a standard domestic dimmer. The latest technology “Dimmerable” energy savers started to be introduced in October 2007 and can be dimmed simply by rotating a standard dimmer switch. Please check to ensure that you are ordering the correct item before using an energy saver with a dimmer switch.

    Are “Energy Saver” and “Long Life” bulbs the same thing?

    Yes and no! Compact fluorescent lamps do generally have much longer life than ordinary incandescent bulbs but there are also many other types of “long life” bulb, most of which do not also save energy. Generally a normal incandescent bulb will have a rated life of around 1000 hours whereas compact fluorescent energy saving bulbs have a rated life of between 3,000 and 15,000 hours. LEDs are more efficient and even longer lasting than CFLs. With average lives of 20,000 - 50,000 hours and higher, they truly are both long life and energy saving.
