Light colour temperature and working benefits.

Zoomup

In a barbers' salon the lighting is mainly ceiling track lighting with G.U. 10  daylight lamps. The barber wants increased lighting so that he can see better to fashion and cut hair and beards. He wants the light to originate from behind the seated customers from high level. I can add more ceiling mounted track heads...but.......is it better to use warm white lamps as opposed to daylight lamps that appear gloomy and grey in colour, regarding the need to do close work. In other  words are warm white lamps better or worse than daylight lamps for doing close work? Or is there no difference?

Oh, and what are the brightest .G.U. 10 L.E.D. lamps available?

Thanks,

Z.

    Two factors influence the choice of colour temperature. 

    Firstly lighting level, in general the greater the intensity of the light, then the higher is the optimum colour temperature. A room lit to say 2000 lux with cool white lamps tends to look "bright, efficient and businesslike" and to be preferred by most. A low light level of say 20 lux tends to look more attractive with warm white lamps.

    Secondly personal preferences vary a lot.

    But in general high light levels = cool white lamps

    Low light levels=warm white lamps.
