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,
