Cocoweb's Plug-in 22” Grand Piano Lamp showcases the finest piano lighting in classic style. This lamp is handcrafted from quality brass and aluminum, and coated to resist scratches and damage for a lifetime of use. Accented with elegant brass accents, this lamp features a rich black finish to blend in seamlessly with grand pianos of any make or model. Warm LED Lighting Cocoweb lights comes pre-installed with an integrated LED array (bulb), which provides over 50,000 hours of light (20 years with average use), making replacement bulbs a thing of the past. The array has evenly spaced LED nodes to provide a balanced light over the sheet music and keys while you play. Brightness Controller Controlling the brightness of the lamp is essential as having a light too bright can cause discomfort, and too dim can increase eye strain. Cocoweb includes a full range brightness controller (dimmer), allowing you to set the light output to the perfect setting for you. The dimmer has a turn knob so you can get the exact brightness rather than incremental dimming. The dimmer is optional and can be bypassed by plugging the adapter directly into the light. Plug-in Adapter This model of the 22 inch grand piano light operates on a 100-240Vac US Type A plug-in adapter. The adapter has a cord length of 10 feet (120 inches). Premium Felt Lining To protect and preserve your piano, the insides of the light clamp is lined with a soft protective felt that prevents any scratching or damage on the surface of the music board. Multiple Points of Adjustability The 22" Grand Piano Light utilizes a ball joint to allow the entire light bar to rotate in or out, and each side of the light bar rotates independently, allowing you to light up both the sheet music and keys simultaneously. Clamp on Design Cocoweb grand piano lights include a clamp on design allowing them to securely clamp onto music boards that are 1" thick or less. Easy On / Off Toggle Switch This light has an easily accessible on / off toggle switch located on the bottom side of the light bar, making it easy to turn the light on when ready to play or off when you finish. The light can also be powered on and off using the dimming controller. Adjustable Height The piano light is capable of raising or lowering by 7 inches by adjusting the screw on the back of the clamp, ensuring adequate space when turning the pages on your sheet music.
