What is bright light?
Bright light is a kind of light with an intensity between 2,500 lux and 10,000 lux, which is generated by an appliance with special tube lamps. Normal artificial lighting usually has an intensity of only 500 lux. 2,500 lux is the amount of light you receive when sitting by a window on a bright summer's day. The Philips Bright Light has been designed in such a way that, if used normally, it does not harm the eyes or health in general. The Bright Light does not tan or cause any skin reactions because the UV radiation has been filtered out.
