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.
The amount of light that is produced by a lamp is called lumen's and the more lumen's the lamp has the brighter it will be. Lumen's work in conjunction with kelvins and 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 lumen's and you then had another lamp which was a cool white 5,000 kelvins which also produced 300 lumen's 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 onto a dark wall and a warm 2,700 kelvin lamp onto 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 into account the area you want to illuminate and think about Kelvins ( colour ), Lumen's ( brightness) and contrast ( colour of area).
