Every item in the series has a version in see-through mirror glass and one in black glass. Both versions obscure the light source when turned off, but have a different light diffusion and view on the inner construction. The one-way mirror glass creates a spectacular play of overlapping patches of light around the lamp and clearly reveals the light source, the black variant has a soft glowing core that spreads a softer, warmer light.
