Для примерного расчёта мощности светильников можно воспользоваться формулой:
P = pS/N,
где р - удельная мощность на освещение, Вт/м2; S- площадь рассчитываемого помещения, м2; N - количество светильников.
Р = 200 х 50 : 8 = 1250 ватт
Рассчёт уровня искусственного освещения осуществляется методом удельным мощности (методом ватт), основанном на подсчёте суммарной мощности всех источников света (W) в помещении и рассчёте удельной мощности ламп:
P = e x W / S
где S - площадь помещения, е - коэффициент показывающий какую освещённость даёт удельная мощность (напряжённость в сети 220 В, следовательно е = 2,5)
Р = 2,5 х 200 : 50 = 10 Вт
По стандарту в помещении 50 м2 удельная мощность общего освещения светильниками мощностью 100-200 Вт = от 11,7 до 16,9 Вт
В Вашем случае в помещение нужно добавить немного освщения.
