This very versatile reading lamp can be shaped in any direction with its goose neck stem. A ring of 20 LED's provide a bright cool image at 500 lumens. The LED's provide flicker free and anti glare light and are extremely long lasting (life). The lamp is attached to a table with a rubber protected clamp with an opening of 6 cms making it suitable to clip onto a wide range of objects. Powered by a built in battery with USB charging. It is an excellent choice for using along side a non illuminated magnifier.
