By using special materials which deliver 90% reflection of light, Rays has conducted more than 20,000 experiments and tests and developed its unique reflective light board with special reflective angles for fluorescent tubes. Based on geometrical and optical theory, the light reflector can produce multiple diffusion and refraction through various angles, height and width, and direct the wasted light to the dark zones to form  "visual lighting". The array of light tubes can be spaced further apart, fully utilizing the light source.
