LED Lighting FAQ
What are LED lights?
A. Light Emitting Diodes (LEDs) have been in common use for over half a century, mainly in electronic equipment, where they’re used as signals and indicators (standby lights, for example). It is only in recent years that LED light bulbs have been widely available. They are an energy efficient, longer lasting replacement for incandescent light bulbs. They emit the same brightness as traditional bulbs, using only a fraction of the power.
Why are LED light bulbs ỏe expensive?
A. LED light bulbs are still a relatively new technology, and in the past they have been much more expensive than traditional bulbs. However, in the last 6 years, the price of LED light bulbs has dropped by around 80%. While they cost more upfront, LED bulbs will actually save households money, thanks to their energy efficiency.

Why buy LED light bulbs?
A. LED bulbs consume 90% less energy than traditional light bulbs. They also last 10-20 times longer. Over the lifetime of a typical LED light bulb, households could save a significant amount of money from reduced energy bills. Unlike energy saving CFLs, LED light bulbs can also be recycled.
Are LED bulbs dimmer than traditional bulbs?
A. No. LED light bulbs use a lot less energy than incandescent bulbs, but are just as bright. When shopping for LED bulbs, remember that the wattage doesn’t denote its brightness. A 5W LED bulb is as bright as a 50W incandescent bulb. The lumens (lm) rating of a light bulb is instead the best indicator of its brightness.
Can i use LED light bulbs with a dimmer switch?
A. Some LED light bulbs are dimmable. They may need specific LED dimmers to operate correctly, however. A dimmable LED may not work correctly, or at all, if used with a non-specific dimmer switch. Always check product listings for compatibility before purchase.

Q. Are LED light bulbs waterproof?
A. A bulb’s Ingress Protection (IP) rating will tell you if it’s suitable for wet environments. The IP rating is a two-digit number: the first digit indicates how protected the light is against the ingress of solid objects, while the second tells you how waterproof it is. The higher the numbers, the more protected it is. An IP rating of 65 is recommended for any bulb that will be used in wet areas
How long do LED light last?
A. The lifespan of LED bulbs is many times that of incandescent bulbs. Typically, LED light bulbs have an average rated light of anywhere from 15,000-20,000 hours, compared to just 1,000 for traditional bulbs. More durable lights could have a lifespan of 30,000 hours or more. Click here to learn more about the lifespan of LED light bulbs.
Why are LED bulbs use less power?
A. Traditional incandescent light bulbs generate light by heating a small filament until it glows brightly. Unfortunately, this means that up to 90% of the bulb’s energy is lost through heat. LED bulbs are instead illuminated by the movement of electrons in a semiconductor material, a process that generates very little heat. Much less energy is wasted this way, so the bulb can achieve the same brightness as an incandescent bulb while consuming much less power.

Q. What are "smart"n light?
A. Smart lighting systems connect to your home Wi-Fi network, allowing you to control your lights through your smartphone or tablet. You can change the colour or colour temperature of your lights in an instant, or set schedules so the lights activate according to the timings you set. Some smart lighting systems are compatible with smart home systems like Amazon Echo, giving you the ability to control your lights with your voice.
Q.Are LED lights safe?
A. The European Commission recently published a report that found no evidence to suggest that LED lights are harmful in normal use.
Will LED light bulbs work with my current light fittings?
A. There is a direct LED equivalent for almost any incandescent bulb, and they are compatible with existing light fittings. They are available in a variety of cap types, including the most common B22d bayonet cap (BC) and E27 Edison screw (ES). Some specialist light bulbs, such as oven and microwave bulbs, do not have an LED equivalent yet.
Q. What are lumens?
A. Lumens (lm) are a measure of the amount of visible light that a lamp emits. It is used to determine the brightness of a bulb (unlike a bulb’s wattage, which has no direct relation to its brightness). A typical bulb for use around the home might have a lumens output between 300-500lm, while high-powered floodlights can have a lumens output in excess of 20,000lm
