What does LED stand for?
LED stands for Light Emitting Diode, an example of solid state
lighting.
How much energy can I save if
I change to LED's
Of course lights for various purposes will have different
specifications but on average an LED will use 1/8th of the power of
a standard incandescent bulb. Most commonly used LED bulbs
use between 1 and 7 watts. Rarely will you see an LED that
uses more than 15 watts of power. This means that in
general, LED's use less power than compact fluoro bulbs which are
currently being marketed as 'energy saving'. For a detailed
comparison of various forms of lighting visit our comparison
table.
Why do I need to change
anyway?
In February 2007 the Australian government enacted a law that
will ban the sale of most incandescent bulbs by 2010. Until
recently the only alternative we had been given was to use compact
fluorescent bulbs which contain hazardous levels of mercury.
LED's are a far cleaner and safer choice.
Why haven't I heard of LED's
before?
LED's have been around for decades in our cars and as
indicators on electronic devices but their use was limited by
manufacturers inability to create a white LED. Recent developments have made a
white LED possible and the LED has since moved ahead in leaps and
bounds to the point where we can now offer an LED alternative for
any lighting application. Cost had also been a prohibitive factor
in popularising LED’s but as you can see from our prices
cost is no longer a concern, particularly when the LED’s long life
and energy efficiency are taken into
consideration.
How much do LED's cost compared to other lights on the
market?
The price of LED's varies depending on the application and the
number, size and quality of LED's included in any one light
bulb. In many cases LED's are available at a price that
is comparative to compact fluorescent bulbs. When
considering price, attention should also be given to how much
energy LED's save therefore reducing power bills and their
extremely long lifespan (up to 50 000 hours). Please refer to
our Comparison Table to get a comprehensive guide to the
benefits and costs of different types of lighting.
I have heard heat is a problem for
LED's?
Yes, heat is an LED's Number 1 enemy. When too much
wattage is pushed through an LED it creates too much heat and the
lamp will fail. This is the reason manufacturers have taken a
long time to develop brightness in small bulbs such as a 50W
halogen replacement, it is very difficult to create that level of
brightness in such a small area without also creating too much
heat. The environment in which the LED bulb is placed can
also impact it's lifespan. Ambient temperatures should be
between-20oC - +45oC and the bulb should be
adequately ventilated to allow any heat generated to dissipate. The
surface temperature of an LED will be approximately
50oC-60oC which is not too hot to touch but
probably too hot to be comfortable holding for long.
How long do LED's
last?
LED's may last up to and in many cases beyond 50 000
hours
Will I be able to put my
new LED bulb straight into my existing light fittings?
Yes. Our range of LED's comes in a range of bases and sizes
to fit most commonly used existing light fittings, with the
exception of the Tubelights and G24 bulbs which need to have the
starter removed and the ballast bypassed before they can be
installed. This must be done by a qualified electrician in
order to retain the warranty on these products.
Will LED's work with existing
dimmers?
No, you can't use LED's with existing dimmers. This is
something that manufacturers are working on and we hope to be able
to overcome in the future but at the moment using an LED bulb
on a circuit which includes a dimmer will void your warranty.
Are LED's as bright as normal
incandescent bulbs?
In the past LED's have had a reputation for not being bright
enough, you do need to be careful what you are buying and who you
are buying them from. Individual LED's can vary greatly in
size and quality. We have personally tested all
the LED's we sell on this site and we give an approximate
indication of the wattage of the incandescent bulb they are an
effective replacement for. LED light is usually more
directional than incandescent light and they do emit a
different kind of light to incandescent bulbs, it is
recommended that you install them and give yourself a day
or two to get used to the different look of the room.
The first time you turn them on the room may feel quite different
but you'll find after you've been away and then re-entered the room
a couple of times you get used to the new look very
quickly.
What is the difference between
warm white and cool white?
Lights come in different 'colour temperatures', warm white is
between 2500k and 3500k and has a yellowish glow. Cool whites
are between 5500k and 7000k and contain more blue tones,
they are closer to the colour of daylight and are good for
concentration. The warm white and cool white descriptions are only
a guide to colour within a certain range, different bulbs or
different batches of the same bulb may vary in colour within that
range. Visit our 'Warm
White or Cool White' page for a more detailed explaination.
Why should I choose LED's over
compact fluorescent light bulbs?
LEDs' are the superior choice for a multitude of reasons.
- LED's use very little energy, often far less than
the compact fluorescent bulbs that are currently being
marketed as 'energy saving'. This translates to significant savings
on your power bill.
- LED's may last up to and sometimes beyond a staggering 50
000hrs+ which means they can last 10 years even with heavy
usage. This makes them much cheaper than other bulbs in the
long term but also saves the time and inconvenience of having to
change bulbs regularly, particularly in hard to reach places.
- LED's emit no UV light and are safe for people with health
problems that are affected by fluorescent lights.
- LED's produce very little heat, greatly reducing the strain on
air conditioning systems and therefore further reducing energy
comsumption
- LED's can be retro fitted into most standard lighting
fixtures.
- LED's emit no audible buzz that can make fluorescent bulbs very
annoying and interfere with radio frequencies.
- LED's are mercury free, they pose no immediate threat if they
are broken and they do not require hazardous waste disposal.
Compact fluorescents are highly toxic if broken and do
require hazardous waste disposal.
- LED's come in a huge range of styles and colours to suit any
application.
- LED's are shock and vibration resistant, there are no fragile
filaments that can be easily damaged.
Disposal is a big problem for
compact fluorescents, how should LED's be disposed of?
Firstly, you shouldn't need to dispose of your LED bulb for at
least 10 years! If a bulb is broken, it poses absolutely no
immediate health risk, simply sweep up the pieces and place them in
the bin. Landfill is the recommended method of disposal.
What are Cree LED's?
Cree,
Inc. is a market-leading innovator and manufacturer of
semiconductors that enhance the value of LED solid-state lighting,
power and communications products by significantly increasing their
energy performance.
Many of our products use high quality Cree
LED's
What are the
CE and RoHS Certifications?
The CE marking is a mandatory European marking for
certain product groups to indicate conformity with the essential
health and safety requirements set out in European Directives. To
permit the use of a CE mark on a product, proof that the item meets
the relevant requirements must be documented.
The RoHS Directive stands for "the restriction
of the use of certain hazardous substances in electrical and
electronic equipment". This Directive bans the placing
on the EU market of new electrical and electronic equipment
containing more than agreed levels of lead, cadmium, mercury,
hexavalent chromium, polybrominated biphenyl (PBB) and
polybrominated diphenyl ether (PBDE) flame retardants.
Do you offer a
warranty?
Yes we do. All the products sold on this site come with a
12 month warranty on faulty goods.
