LED
LED is highly energy-efficient
lighting
LED, aka Light Emitting Diode, is
highly energy-efficient, energy-saving, with much longer life-span than
incandescent lamps and even energy-saving lamps. An LED uses 90% less energy than a traditional
incandescent lamp to give out the same amount of light or same level of
lumen. LED is a cool light source; the
amount of heat it generates when being lit is much lower than traditional
lamps, hence reducing demand on indoor air-conditioning or cooling system.
New generation of LED is mercury
and infrared/UV free, and will not create colour fading effect on the lit
objects, making LED a green and energy-saving lighting choice.
Long Life Span reduces maintenance cost
LED life span refers to the total amount of
lit hours that the LED lamp having its original lumen level dropped to below
70%.
Most good quality LED has a rated average
life of 15,000 to 30,000 hours, depending on its usage and model. For most well-recognized LED brands, the LED
can still be used even after it reaches its 70% lumen threshold.
With long product life, seldom replacement required, meaning LED can bring significant maintenance savings.
Lumen and Wattage
When buying a lamp, look at its lumen (unit
shown in ‘lm’) to check its level of brightness. Lumen is the measure of the
total quantity of visible light emitted by a light source.
How much electricity a lamp consumes is
indicated by its wattage (unit shown in ‘W’).
LED is highly energy-efficient because:
E.g. an 2.5W LED bulb has a lumen output of 115 lm, while a 15W traditional incandescent bulb needs 15W to generate the same amount of 115 lm of light output (i.e. using 5 times more electricity!)
