Frequently Asked Questions

Will I save money and energy by switching to LEDs?
If you buy quality LED lamps, you will almost certainly save money and energy and will last longer than incandescent lamps. There are lots of poor quality LED lamps on the market that will not necessarily last long enough for the money saved on lower energy bills to equal the higher purchase cost of good quality LED lamps.

Are LEDs safe?
Yes, LEDs do not contain mercury. They give off comparatively little heat, making them safer to handle after prolonged use. Almost all LED chips actually operate on low voltage so it is possible to power an entire buildings LED lighting system on a safe low voltage power. The absence of glass enclosures and fragile parts also reduces the probability of breakage.

Are LED bulbs dimmable?
We offer both dimmable and non-dimmable LED bulbs as well as dimmers & controls.

LED bulbs can only be used with a dimmer switch if they specifically state it is dimmable. For an optimum performance, the trailing edge dimmers is required which have lower minimum loads of are designed to be used with LED bulbs.

Do LED bulbs switch on immediately?
LED bulbs are come on instantly, and come up to full light output with microseconds when switched on and do not suffer from rapid switching weakness. LED bulbs do not give off any potentially harmful IR (infrared radiation) or UV (ultraviolet radiation) emissions.

Does the level of light produced, reduce over the lifetime of the LED bulb?
There is a slow and gradual reduction in light output over time. The Lifetime - L70 value is an industry approved standard for quoting the average rated life of the LED product and states the number of hours at which a product is expected to perform above 70% of its prime performance.

Why do LEDss use less power than a compact fluorescent lamp?
LEDs do not use a filament where a conductor is heated and light is created. Filament based lighting consumes more power than the light produced. LEDs produce very little amount of heat and do not use filaments making them far more efficient in consumption and output.

Is LED light a different type of light?
LED lights are thought to be safer and healthier. LEDs do not produce any sort of ultraviolet radiation which causes colour fading. With LED lights, there is no noise or flickering.

Should LEDs be used in enclosed fixtures?
Not if they are completely enclosed. In order for an LED to function correctly, they must be in a non-enclosed fixture to allow for heat to dissipate from the heat sink. Otherwise, they can overheat and may fail early.

Are bulbs with more LEDs brighter than bulbs with less?
The number of LEDs is not the determining factor of the bulbs brightness. Different types of LEDs vary greatly in size and light output. The most accurate indicators of the brightness of Led bulbs are the measured lumens or lux. Lumens measure the total amount of light is on a surface at a specified distance.

Is an LED going to produce enough light to replace my existing bulb?
For most applications, it will.

What is thermal management and why does it matter?
Heat generated by electronic circuitry must be dissipated to improve reliability and prevent premature failure and degradation of the lamp. A typical lamp will degrade significantly for every increase of 10 degrees Celsius, and this applies to all lamp technologies. In ceilings, temperatures can rise to 65 degrees. The best performing lamps will have a well-balanced combination of driver, chip and heat sink, which will provide the most consistent light level and colour over the longest lifespan.

What are the advantages of LEDs compared with the conventional incandescent lights?
There are several obvious advantages LED;s have over traditional incandescent light bulbs, they are as follows:

• Low power consumption – energy saving
• Long lasting
• Cold lighting
• Ruggedness
• Small size and weight
• Fast switch times
• Simple to use

Is the lifespan reduced if the LEDs are frequently turned on and off?
Unlike discharge lamps, LEDs are semiconductors and their life span is not affected by the number of times they are turned on and off.

What are the factors that affect the lifespan of LEDs?
LED light bulbs behave differently from traditional lights. Factors that will affect the life span of LEDs include power supply, ambient temperature and components. High quality heat sinks have to be designed to prevent premature failure of LEDs. Higher ambient temperatures than that for which the product is rated also reduces the life of the LEDs.

Could you give a more detailed explanation about these LED advantages?
Yes, currently available LEDs are more energy efficient than incandescent bulbs, but less than florescent bulbs with the same light output. The power consumption of popular LEDs ranges from 30mW to 200mW. People can save money and energy by using LEDs instead of equivalent incandescent decorative bulbs.

The rated average working life of LED is around / up to 50,000 hours compared with 1,000 hours of incandescent bulbs.

LEDs emit cold lights as working LEDs generate very small amount of heat, so LEDs are much after than equivalent incandescent light bulbs in terms of danger of fire. LEDs do not have filaments to heat up in order to emit lights just like the case of incandescent bulbs. Lights are emitted from LEDs as a result of energy exchange occurring in the different semiconductor materials an LED is made of.

LEDs are usually shielded with solid transparent plastic materials so they are more rugged than incandescent and florescent bulbs that are usually sealed with glass.

LEDs can be powered by either AC voltage or DC voltage. The circuit that is required to appropriately drive LEDs is much simpler than that for florescent bulbs.

Are they more efficient than traditional lighting?
LEDs work in a completely different way to traditional lighting as they typically use 75% less energy whilst producing the same amount of light.

Why should I buy LED bulbs? With rising energy costs, it is critical to improve your households energy efficiency. Around 11% of an average British households electrical usage is attributed to lighting. One of the easiest steps you can take towards greater energy efficiency can be done in a matter of seconds - change your old light bulbs to LED bulbs. LEDs consume far less energy than incandescent, halogen, or compact fluorescent bulbs. You will save money and reduce carbon emissions - all from replacing a tiny light bulb!

What are the economic advantages of using LEDs over conventional light sources?
Although the cost of conventional light bulbs is less than LED versions, they do not take into account the operational and maintenance cost of the lighting system. LEDs, on average last significantly longer, reduce maintenance and lamp replacement cost. This reduces cost of labour to replace lamps and the cost of new lamps at the end of lamp life cycle. LEDs, also consume less energy. Overall the cost of a LED lamp can thus be significantly lower than conventional lighting systems when they are compared side by side over time.

Where is it appropriate to install LED bulbs?
LED light bulbs are appropriate when you need powerful directional lighting. Presently, LEDs excel over other bulbs in spot and flood lighting applications. Track lighting, spot lighting, canister lighting, and outdoor flood lights are currently the most common places to use and replace incandescent bulbs to LED versions.

Do your LED bulbs contain mercury?
Our LED bulbs are mercury-free and meet the strict requirements of the Restriction of Hazardous Substances Directive (RoHS).

Do LED bulbs work in regular light sockets and fixtures?
Yes, LED light bulbs will work in most standard light sockets and fixtures, such as Edison screw-in base and MR16 track lighting.

Are LEDs easy to install?
Yes, installing or changing an LED light bulb is like changing any other bulb, with the advantage that you will need to change it far less often!

What precautions are/can be taken when mounting LED drivers?
LED drivers need to be mounted in a ventilated space. Access to the driver needs to be provided for general maintenance purposes. The IP (Ingress Protection) rating of the driver needs to be considered before finalising the mounting location of the driver (only those drivers designed for outdoor environments can be installed outdoors). The distance between the driver and the light source needs to be taken into consideration to prevent voltage drop that results in reduced output of the LEDs.

How bright are LED bulbs? What is the light quality of an LED bulb?
The light quality of LED is terrific - equal to or better than conventional bulbs. There is no radiant glare and LEDs produce a cleaner light quality.

Most people discuss light brightness in terms of lumens. One important thing to understand is that colour temperature is an important consideration alongside lumens. For example, a light bulb may have high lumens, but a low colour temperature, resulting in poor colour rendition. So, although a light is supposed to have a high light output, its low colour temperature renders visible objects very poorly. A good experiment you can do is to observe a yellow-coloured street light at night - the light gives off a lot of light (high lumen output), but it is still very difficult for your eyes to perceive objects. Now, contrast this with a light bulb that may or may not have high lumen output, but has a higher (whiter) colour temperature. In every case, even at a lower lumen output, a higher colour temperature means that your eyes will better perceive objects and colour.

Although LED light bulbs may have lower lumens than conventional bulbs, they compensate with their excellent colour temperature, especially true with outdoor lighting, a higher colour temperature (whiter bulb) translates into better lighting.

Do LED bulbs give of heat?
LED light bulbs only give off ambient, room temperature heat around the LED itself. One reason LEDs are efficient is due to the low amount of heat around the LED diode junction. To accomplish this efficiency, heatsinks are required to draw heat away from the LED junction. The heatsink may get hot, so be careful not to touch it.

What transformer can I use with MR16 LED bulbs?
You should use a transformer rated 12V only. As good general practice, please test your transformer's voltage before using LED or any other light bulb. A transformer not operating at 12V will create bulb flicker and potentially ruin the bulb.

Is low voltage or a main circuit better for an LED?
We generally recommend that you use mains voltage unless you are using an LED driver to run 12V lamps. Drivers and transformers not designed to run LED bulbs will cause premature failure and are not covered under our warranty. This issue relates to all LED lamps bulbs irrespective of manufacturer. We always recommend that you consult an electrician who is familiar with LED lighting products if you are unsure.

Do your LEDs work with dimmers?
We do not recommend using our LED bulbs with traditional dimmer switches, as it may diminish the lifetime of the bulb.

Why is the colour of LED important?
Most LEDs are monochromatic. Light colour is associated with the light wavelength. LEDs are made with different semiconductor materials emit lights in different wavelengths. LED light wavelengths range from 400 nanometers (blue) to 800 nanometers (red) and 2700 Kelvin to 7000 Kelvin for white. The colours of popularly available LEDs in the market are red, orange, amber, yellow, green, blue and white.

You make all these amazing claims about your products but, how can I be assured they will actually deliver these promises of efficiency and light output?
We appreciate that, as LEDs are a new technology there is a lot of inconsistency out there in performance and claims made. We thoroughly test all our fittings on site and all our designs are independently tested for performance.

How do we know that your LED lamps are better than your competitors?
We are not tied to any one manufacturer of LEDs so we can afford to test various products from different manufacturers to ensure we are getting the best components and designs for our products. We specify technology that protects the LEDs ensuring no matter what the indoor or outdoor conditions are, we are confident that the LED life always remains within its optimum operating parameters.

We ensure all of our components are of the highest quality and are tested by 3rd party test houses. We are also aware of other potential issues with changing from the traditional lighting to LED. We have components within the system we provide to alleviate these problems, otherwise within a couple of years the clients will see many failed power supplies on the lights.
