Why switch to LED lights?

Because LED lights are not only more efficient than traditional lighting, they last longer (up to 50,000 hours), emit no infrared or ultraviolet radiation, turn on instantly, and are more durable. LED lights use much less electricity than traditional lighting – up to 90% less than incandescent lighting and up to 40% less than fluorescent lighting. Unlike fluorescent lights, LED lights contain no toxic substances such as mercury or lead, and most comply with RoHS standards. LED lights produce significantly less heat than traditional lighting resulting in reduced fire risk and air-conditioning cost savings.

What is an LED?

LED stands for Light-Emitting Diode, which is a solid-state electronic device containing chemical compounds that emit visible light when an electric current passes through them. Unlike incandescent lamps, LEDs have no filaments that can burn out or fail.

What are the benefits of LED lighting compared with traditional lighting?
  • Long operating life – usually more than 50,000 hours.
  • Low power consumption – around 60% to 90% more efficient than incandescent lighting and 20% to 40% more efficient than fluorescent lighting.
  • Environmentally friendly – contain no toxic materials such as lead or mercury, and made from recyclable metals such as aluminium and copper.
  • Low heat output – reduced fire risk and air-conditioning cost savings.
  • Reduced maintenance – need to be replaced less often.
  • No infrared (heat) or ultraviolet radiation – will not damage artworks and artefacts.
  • Durable – much more resistant to shock and vibration.
  • Instant on – need no time to ‘warm up’, unlike fluorescent lights.
  • Flicker free – unlike fluorescent lights.
How do LED lights differ from traditional lighting?

Incandescent lamps produce light by heating a thin filament of metal to a very high temperature. Fluorescent lamps produce ultraviolet light when electricity is passed through a mercury vapour, causing the coating inside the fluorescent tube to glow or ‘fluoresce’. Neither of these systems is as energy efficient as LED lights, which use semiconductors to produce light, have a longer lifespan, and are more durable.

Can LED lamps be used in existing light fittings?

Yes, most of the products we sell are fully capable of being retrofitted into existing light fittings. In some cases you may need to replace your existing transformers with a compatible LED driver (we supply LED drivers with all products that require them).  See our product pages for more information.

Can LED lights be dimmed?

Yes, we offer dimmable options for some of our lights – see our products pages for more information.

How efficient are LED lights compared with incandescent lights?

LED lights are generally between 60% and 90% more efficient than equivalent incandescent lights, emit less heat, and last many times longer – up to 50,000 hours compared with 1,000 to 3,000 hours for incandescent lights.

How efficient are LED lights compared with fluorescent lights?

LED lights are generally between 20% and 40% more efficient than equivalent fluorescent lights, do not contain toxic materials such as the lead and mercury found in fluorescent lights, and last many times longer – up to 50,000 hours compared with 5,000 to 10,000 hours for fluorescent lights.

Do LED lights contain mercury or lead?

No, unlike fluorescent lighting technology, LED lighting products do not use mercury or lead. Most of the products we sell conform to RoHS standards. See our glossary for more information on RoHS compliance.

Why do LED lights last so much longer than traditional lights?

LED lights produce light in a much more efficient way than traditional lighting so less energy is wasted as heat. And because LED lights produce minimal heat they are less prone to wearing out over time. In addition, as LED lighting is a solid-state technology (no moving parts, no filaments, and no gas-filled tubes), LED lights are less prone to failure by heat, shock, or vibration, and can be cycled on and off without excessive wear.

Why are LED lights more expensive to buy than traditional lighting?

LED lights generally cost more upfront than traditional lighting but are much cheaper in the long run due to lower operating and maintenance costs. The solid-state technology in LED lights is more energy-efficient than traditional lighting but costs more to manufacture, hence the price difference.

Do LED lights produce as much heat as incandescent or fluorescent lights?

No. LED lights produce significantly less heat than incandescent and fluorescent lights. Because LED lighting is highly energy efficient, minimal energy is wasted as heat. Incandescent lights, on the other hand, waste up to 95% of the energy they consume as heat, making them more prone to failure and reducing their operating life. LED lights pose a low fire risk compared with incandescent lights and can also help you save on air-conditioning costs.

What is a heat sink?

LED lights generate much less heat than incandescent lights but they still produce enough heat to affect lamp performance. To move this heat away from the lamp, a heat sink, typically made of aluminium, is incorporated into the lamp design.

Do you provide warranties for your products?

Yes, we provide warranties for most of our products – see our products pages for more information.

How good is the light quality of LED lighting?

LED lights offer exceptional light quality. The latest advancements in LED technology mean that LED lighting can reproduce a wide range of white colours from around 2700K (Warm White) to 6500K (Cool White) as well as producing vivid reds, greens, and blues for accent lighting applications.
