Area of 400 square meters, height of 5 meters, what explosion-proof lamps can guarantee lighting?
Your request is not specific enough. How much illumination do you want? Do you want to see walking or do machining?
LED watts can be a little lower. Generally with this exquisite point, really need to calculate the illumination and effective radiation area, directly ask the lighting manufacturers, these parameters are better.
Or look at your lighting layout, metal halide lamp and high-pressure sodium lamp wattage slightly higher, you are low in height, 200W below can.
