EASE EYESTRAIN WITH BELL & HOWELL LAMPS. Each Bell & Howell lamp has a full-spectrum bulb that simulates natural daylight which can help reduce eyestrain and brighten your mood. Clear, easy-on-the-eyes lighting is great for reading, writing or working on a computer because it doesn't create glare. Adjustable gooseneck lets you shine the light right where you need it. Each lamp includes a 27-watt bulb that lasts up to 5000 hours (and gives as much light as an ordinary 150 watt bulb). UL-listed.
