Our combination lamp makes use of both incandescent and fluorescent light to produce an almost natural daylight. The ceramic socket allows the use of up to a 100 watt incandescent bulb along with a 22-watt tubular fluorescent bulb. Both bulbs are independently switched, allowing the user to select either incandescent light, fluorescent light or both at the same time. This sturdy lamp is made of all metal construction, no plastic parts to break. The lamp has a 46" reach on a spring loaded jointed arm that is mounted to a Tite-Grip metal clamp can be clamped to the edge of any flat work surface up to 2" in thickness. The Tite-Grip mount allows for 360 degrees of rotation. This lamp is available in two colors, White or Black. The universal pin mounting system on this lamp allows the lamp to be used in any number of permanent mounting brackets, table top stands and floor stands (See Stands and Mounts for more details).
