So how do we choose high quality wall washing lamp?
Wall washing lamp refers to whether the luminous Angle is four vertical surface layer, so that the overall target wall can achieve a certain symmetrical chroma, to build a bright and broad visual effect of the building facade; Good wall washing is the pursuit of perfect lighting symmetry, mild and comfortable, no focal length cohesion symmetry.
A, select reliable manufacturers to buy: well-known brands have to ensure that this truth is understood, but a lot of people in order to better map cheap, choose retailers and even non-regular manufacturers of goods, so the quality and after-sales service can not be reasonable to ensure.
