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. Lumen 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 daylight white 6,000 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 6,000
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 temperature),  Lumens (brightness) and contrast 
(colour of  the area) .
