Though originally used in pharmacies because of their simple upkeep -- the glass is simple to dust, bulbs easily changed from removing the shade from below -- this pendant's silhouette is perhaps most famously known by students of the 1950s as ""the schoolhouse pendant"" thanks to a large government order that made this the official light of chemistry labs until the mid-70s when fluorescents were installed (forgive them!). We took inspiration from the original -- gracious curves, simple upkeep, and adjustable drop -- because if there is one thing we have learned, it's that great design never goes out of style.- Care Instructions: Before cleaning any lamp shade or fixture, disconnect the power source. Wipe with a soft, dry cloth. Avoid the use of chemicals and household cleaners as they may damage the finish.- Primary Material: 80% Metal/GlassProduct Specifications:- Finished in chrome, the metal and glass body would suit any color palette and won't oxidize- As this fixture must be hardwired, we recommend a professional electrician manage installation- Eco-friendly 4W LED bulb included- Takes one bulb and compatible with any 9W LED or 40W TYPE ""A"" or 13W CFL- UL Listed
