The engineers at Lotus Design have employed new advancements in LED and battery technologies to create the Lotus Design Model LEDLUX14 Rechargeable Music Stand Light. The Model LEDLUX14 uses 14 innovative CREE LED lamps which produce a warmer 4000K white light and are more energy efficient. Unlike other lights, the 14 LEDs are closely spaced to spread the light evenly and avoid shadows and glare. Lotus Lights are powered by a powerful rechargeable lithium polymer battery. Like other modern mobile devices, just plug the included power supply into the light to recharge the battery. The power supply adapts to the line voltage you plug into, so you can use it anywhere in the world with an inexpensive plug end adapter.. The Lotus Light Model LEDLUX14 features a 13" shade and a runtime of 6hrs 40min on low power and 3hrs 20min on high power. It comes with the detachable clamp, neoprene travel pouch, and AC Adaptor(US).
