Example of LED lamp energy savings
Lamp colour ( Kelvins )
The colour of a lamp is defined as a measurement called kelvins. A standard GLS light bulb in your house would be 2,700 kelvins
which is in the warm colour spectrum and a lamp with 5,000 kelvins would be at the very cold white spectrum. Getting the
right colour temperature of a lamp does matter as the warm colour wavelength helps to soften the tone of the area and gives
a warm soft relaxed feel and ideal for colourful flower beds and rockery areas especially with wooden bark and at the other
end of the scale a 4,000 to 5,000 kelvin lamp colour would be used against a light background such as white walls or to accentuate
grey blueish foliage in shrubs and small trees. When you buy a new, energy efficient bulb, keep your application and
colour scheme in mind and make sure to buy the bulb with a colour temperature to match.
Light output ( Lumens )
The amount of light that is produced by a lamp is called lumens and the more lumens
the lamp has the brighter it will be. Lumens work in conjunction with kelvins and
watts should not be taken in isolation of each other, for example if you had a very
warm white lamp at 2,700 kelvins and it produced 300 lumens and you then had another
lamp which was a cool white 5,000 kelvins which also produced 300 lumens the cooler
lamp colour would always appear brighter to the naked eye than the warmer one this
is due to the receptors in the eye that react better to a white light spectrum. Another
factor on how bright a light may appear is contrast so if you shine a white 5,000
kelvin light on to a dark wall and a warm 2,700 kelvin lamp on to a white wall the
warmer lamp would appear brighter due to the contrast of the material it is focused
on. So when choosing a lamp always take in to account the area you want to illuminate
and think about Kelvins ( colour ), Lumens ( brightness) and contrast ( colour of
area ) The more lumens produced per watt the more energy efficient the lamp will
