FAQ
CAN YOU EXPLAIN TO ME WHAT A LED LIGHT IS?
A LED, or light emitting diode, is a semiconductor light source that produces light in a much more efficient manner then conventional lighting technologies such as the incandescent and fluorescent lighting.
Technically, a semiconducting chip is doped (intermixing impurities into a semiconductor of high purity levels to modulate electrical properties) to create what is called a p-n junction. The ‘p’ represents the anode from which electrons flow into the ‘n’ or cathode. “Charge carriers” taking on the form of ‘holes and electrons’ flow into the p-n junction where upon electrons to fall into holes of a lower energy level, causing energy to be liberated in the form of photons. This process, known as electroluminescence, leads to light being generated.


WHAT MAKES LED LIGHTS BETTER THAN OTHER CONVENTIONAL LIGHTS?
LEDs innovative design provide many advantages over that of traditional light bulbs including a longer shelf life, lower energy consumption, size, and an overall improved robustness. Not only are they much more environmentally friendly compared to that of CFL and fluorescent lighting, which contain mercury and other harmful toxins, but also are available in a diverse range of styles, shapes & sizes.


HOW LONG DO LED LIGHTS LAST?
The usual length of time that LED lights last is generally between 30,000 to 50,000 hours. This length of time can vary somewhat depending upon the quality and type of driver used and the number of power surges and electrical fluctuations that the lights are exposed to. Our LEDs are rated to last for more than 10 years, powered by high quality drivers and the revolutionary CREE chip, this type of lighting truly is a smart investment!


WHY ARE LEDS MORE EXPENSIVE THAN CONVENTIONAL LIGHT BULBS?
Considering that LEDs are made using durable, high quality materials that are designed to be shock and heat resistant, joined with the additional manufacturing costs required to produce them, LED lights are often more expensive than their inefficient conventional counterparts. This added cost is readily recouped though through an energy saving of up to 90% on household lighting costs and a much longer shelf life.


IS IT TRUE THAT LED LIGHTS ARE MORE ENERGY EFFICIENT THAN OTHER LIGHTS?
Yes. Light emitting diodes are designed in such a way that enables small amounts of electricity to efficiently generate a large amount of light. LEDs innovative design converts approximately 90% of the electricity used into light, whereas traditional incandescent and florescent lighting technologies utilize a mere 10 – 15% of the electricity, with the rest being lost as heat. This leads to LEDs being much more efficient and heating up to a much lesser extent.


WHAT IS THE DIFFERENCE BETWEEN CREE, EPISTAR & BRIGELUX LED LIGHTS?
The main point of difference between CREE LED lights to that of Brigelux & Epistar is the chip technology that the LED light contains. Taking the lead in the lighting industry for their advanced design, CREE LED chips are much more advanced than their counterparts, producing more lumens per watt of electricity used, whilst possessing a much greater efficiency rating than Brigelux & Epistar models.

WHAT TYPE OF FITTING PIECE WILL I NEED?
When purchasing it is important to know what kind of light fittings you currently have installed in your home or business and to purchase lights with that kind of fitting. For example, if your household lighting currently has GU10 light fittings then you will need to purchase GU10 LEDs, otherwise the light will not fit. Presently, we stock the most commonly used fittings including MR16, GU10, E27 & B22 models. For more information pertaining to fitting types, and pictures outlying how these fittings look, please check out our LED fitting types page.

I’VE HEARD THAT SOME ENERGY EFFICIENT LIGHTS SUCH AS CFL’S CAN BE DANGEROUS. IS THIS TRUE?
Prior to LED lights coming onto the marketplace the mainstay energy efficient lighting source came in the form of a CFL, or Compact Fluorescent Light. Despite being efficient, they are in effect quite similar to neon fluorescent tubes predominantly used in kitchens and office spaces. Such lighting gives off a blue-white luminescence and uses much less energy than other conventional lighting sources such as incandescent and halogen lights. Despite this, CFL and fluorescent light sources contain mercury and a variety of other harmful materials that are detrimental to ones’ health. Being made from glass these lights can and often do break making them a significant health and safety issue for households and businesses alike.
LEDs on the other hand do not contain such toxic materials, come in a wide variety of stylish designs, are durable and do not flicker like CFL and Fluorescent lights.

DO LEDS BURN OUT THE SAME WAY TRADITIONAL LIGHT BULBS DO?
LEDs work differently than traditional lights and they do not use a filament. Traditional lighting sources have a filament that heats up, and upon doing so it produces light. Incandescent bulbs continually repeat the heating cycle, which causes the filament to fail. Since LEDs do not have filament within them, but rather a semi-conductor diode, they can last for more than 50,000 hours. Instead of burning out, after many years, these lights will simply begin to fade.


IS IT POSSIBLE TO GET DIMMABLE LED LIGHTS?
YES. The majority of our lighting products are dimmable and can readily be integrated into your existing household fittings, providing you have a dimmable lighting system already in place.

WHY DO SOME LED LIGHTS REQUIRE TRANSFORMERS AND OTHERS DO NOT?
The reason why some lights require transformers and others do not is due to how the buildings wiring is set up. Most households use high voltage 240V AC, which is more compatible with the majority of appliances and electrical goods sold on the marketplace.
MR16 lights run on 12V Direct Current (DC) and as a result will require a transformer if used within a 240V wiring system. Conversely, GU10, E27 & B22 LED lights operate on 240V Alternating Current (AC) and as such will not require a transformer to operate if you have a 240V electrical system set up.
Prior to purchasing LEDs it is always prudent to find out how your house hold wiring system is set up to determine which type of light fitting you will require.


CAN YOU EXPLAIN WHAT THE TERM BEAM ANGLE REFERS TO?
When choosing an LED it is important to consider what type of beam angle would work best for the area being lit. If the beam angle is too low (less than 45 degrees) then the beam of light will concentrate over a much smaller area, producing a spotlight appearance. Such a beam angle results in limited light distribution for a larger room, but often works well for areas such as kitchen benches or bathroom mirrors which may require such lighting. For general household or business lighting applications having a larger beam angle (60 degrees) is the best option. A beam angle of this variety results in the light illuminating much more of the room and this is often the preferred option for the majority of room types.
