Desk lamps are used often at home and offices. Furthermore, some individuals leave the luminaries on 24/7, when serving as a dim lighting option at night. Because of this, it is important to incorporate robust task lighting techniques to improve the functionality of the fixture.

Beam Angle, Light Diffuser

Desk Lamps are notorious for creating hotspots, because they are usually positioned too close to the target. Using a unit without a dimmer can also contribute to this issue. To address this, one must use a desk lamp with an arm that can be positioned overhead.

A 30-degree beam angle (maximum) is highly recommended for avoiding light spillage. Additionally, individuals should avoid directing the beam on shiny surfaces. A light diffuser can also be applied to the fixture to dampen the intensity of the luminary. This technique is suitable for lamp heads that are close to computer screens. With a light diffuser in place, visual strain is reduced when an individual briefly scans the area, as he or she looks up at the computer screen.

CRI Ratings and Lighting Technology

For clarity during illumination, it is vital to utilize a light source with CRI values above 75 (aim for 80+). Since work performed on desks is usually meticulous and detailed, a fixture with low CRI levels could make color depiction less accurate. This is very applicable to designers, artists, interior designers, architects and engineers.

LED desk lamps are great choices for task lighting. The units offer up 50,000+ hours of use and are safer touch (less heat) than filament or gas-based lamps. Small desks can benefit from LED spotlights, because the units are very compact. Fluorescent, halogen and incandescent desk lamps are suitable for tasks requiring high CRI ratings. However, the outdated lighting technologies are prone to running hot, when left on for long periods of time.
