Diffrient Task Lighting With asymmetric reflector shades and counterbalance adjustments, our new different task lights are shining examples of ergonomic design and superior engineering. This task light utilizes a compact fluorescent bulb to provide an ideal light source while saving energy and minimizing risk of burns. Task lights allow the general lighting levels in the office to be much lower (for comfort and energy savings), and allow workers to set their own lighting levels as required by their age, vision, and tasks. Available with Black or Silver bases.
