Holland 4-Light Flush Mount Light, 4315. The handmade glass in front of Holland’s light source is pebbled on the inside and comprised of domes of varied sizes on the outward-facing side. The open metalwork along the sides not only creates visual intrigue, but also allows for more light to escape the fixture. Whether mounted on wall or ceiling, Holland makes a strong impression, its unique glass plate creating a pleasing diffusion effect.
