These custom glass BLOX, made with clear or frosted glass in any color, include a 9 LED card with white dimmable light. In addition to the image reflection of the optical glass, the LED lighting gives you the ability to easily switch between daylight and artificial light. You can play with the clear and frosted glass knowing that two faces of clear glass will give you complete image reflection of what is behind one side; one face of clear glass and one face of frosted glass will give you the image reflection on the frosted side only. Two faces of frosted glass will not allow image reflection. You can create a pattern of alternating clear and frosted BLOX in any design you wish.
