Ott-Lite's VisionSaver Lamps are designed to bring the visual acuity of natural daylight to your desk or workspace, without glare (or installing a skylight), in an effort to minimize eyestrain and discomfort. While everyone can appreciate less reflective glare on computer screens, graphic designers will be especially grateful for this light's ability to make details and colors appear clearer, thanks its low heat and high contrast. With a double-jointed neck that can rotate to illuminate large areas, the crane lamp features counterbalancing tension springs and a weighted base for stability. The head swings horizontally and adjusts vertically for precise lighting. The lamp can be converted to a clamp-on model for those who need every last inch of desk space. The included 18-watt bulb is rated to last 10,000 hours, replacing up to a 100-watt incandescent for energy savings.
