Fluorescent Lighting
Fluorescent lighting is the "standard" technology for lighting spaces such as offices and classrooms, and is up to four times more efficient than the incandescent lamp. However, older, obsolete fluorescent lighting systems can result in poor light quality and flicker. Advancements in fluorescent lighting systems have resulted in the introduction of new systems that provide improved energy efficiency, lighting quality, and design flexibility.The primary components of standard fluorescent lighting systems are the ballast, which modifies incoming voltage and controls electrical current, and the lamp (bulb or tube), the source of artificial light.
Traditional Systems:
- T12 Fluorescent Lamps: One of the most common, but least efficient fluorescent systems. T12 lamps can be identified by their 1.5-inch diameter.
- Magnetic Ballasts: Magnetic ballasts are common and still used extensively today due to their low initial cost. However, these ballasts are considerably less efficient than new electronic ballast designs and are prone to flicker and humming (particularly as they age).
