Dritz's Flexible LED Light is perfect for sewing machines, sergers, crafts, and more. It has a 13-1/2" flexible arm with an adjustable light head that can be adjusted to any angle. The bright LED bulb has a 10,000-hour life, so you should never have to replace the bulb. The Bendable Sewing Light can operate freestanding on your work surface, clipped to a book or belt, and mounted to a sewing machine or computer with adhesive strips or to a wall with screws. You will need three triple A batteries (not included).
