This method is developed based on the characteristics of acrylic light transmittance. It is recommended to use a lamp tube to emit white light to penetrate the acrylic sheet. If you see yellow or yellowish color, it means that the quality of acrylic is not good. The light rate is very high and the light after penetration is white light, and it does not absorb colored light.
