This is the Mighty Bright XtraFlex Duet Super LED Music Stand Light:

• Black
• Chordless
• Two XtraFlex arms with independent heads with super LEDs
• Each is 3-times brighter than a regular LED
• Use one light or two and because each head has a lense over the LED, the light spreads evenly with no hot spots
• No bulbs to replace
• Requires three AAA batteries (not included!)
