The Issen Flush Mount lighting collection uses a delicate, pressed, White Opal Etched glass diffuser, which is presented in a beautiful pattern representative of an emerald cut diamond and softly diffuses the light. Issen is available in three universally-appealing finishes â€" Chrome, Satin Nickel or Oil Rubbed Bronze - and adds a touch of elegance to surrounding decor. Issen fixtures are round with a 13.5" diameter, and are damp-rated, making them suitable for bathrooms or anywhere beautiful ceiling lighting is desired.
