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 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 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 ), Lumens ( brightness) and contrast ( c olour of area ) .
Example of energy efficient lamps
Choosing the right lamp is a combination of 3 main factors, Lumens, Kelvins and efficiency. Efficiency matters because you want the maximum light output possible ( Lumens ) from the minimum amounts of watts consumed. The latest LED lamps will reduce energy bills with no loss of light output and helps the environment too.
