Fluorescent Electronic Ballast Starting Technology Options Affect Lamp Life

Commercial fluorescent lighting systems consist primarily of T8 lamps and electronic ballasts. While LED linear tubes now compete as replacements for traditional fluorescent, the vast majority of existing and replacement ceiling lighting in offices, schools, hospitals and other institutions is fluorescent. At it’s best, fluorescent lamp/ballast systems can offer efficiencies, lamp life and cost effectiveness that rival LED.…

What is the Difference Between Fluorescent and Germicidal Bulbs?

Fluorescent vs. Ultraviolet bulbs

Most germicidal bulbs look like linear fluorescent light bulbs. They have the same shape. They share similar base types. Both use low pressure mercury arc technology. They both have hot cathode and cold cathode lamp types. And both produce the same ultraviolet radiation inside the bulb. So what’s the difference? The fluorescent bulb is coated on the inside…

Some Fluorescent Bulbs Use Amalgam Technology. What Does It Do?

The performance of both fluorescent tubes and compact fluorescent light bulbs deteriorates in ambient temperatures that rise above certain design parameters. CFLs are particularly affected. At high fixture and room temperatures, light output and color characteristics deteriorate. The reason has to do with mercury vapor pressure within the lamp, which depends on temperature. Some fluorescent…

What to Know About Mercury in Light Bulbs

Mercury is highly toxic to humans and wildlife. Fluorescent tubes, compact fluorescent, germicidal, blacklight, metal halide and other HID light bulbs all contain mercury compounds. Incandescent, halogen and LED bulbs do not contain mercury. Extreme care should be taken in both the handling of broken light bulbs and the disposal of burned out bulbs that…

Upgrade T8 Fluorescent Lamps to Improve Light Quality in Classrooms

overhead fluorescent lighting in classroom

There have been several studies in the last few years documenting the positive affect of daylight on student alertness and academic performance in classrooms. Today, daylight harvesting is a major component of integrated lighting designs for newly built schools. For existing schools, expensive remodels to bring more natural light into the classroom may not be…
