Electronic Ballasts: Relief for the Senses (IAEEL 1/96) New research on fluorescent lighting indicates that light modulation ("flicker") at invisible frequencies from conventional fluorescent lighting may induce discomfort in humans claiming hypersensitivity to electricity.

In The Dark About The Lumen (IAEEL 2/95) The present definition of the lumen is based on experiments performed in the 1920s and may be inaccurate for nighttime tasks such as driving, writes guest author Mark Rea.

High-quality task lighting (IAEEL 3/93) Electronic high-frequency ballasts offer several advantages over standard electromagnetic ballasts:

The ABCs of UV (IAEEL 3/93) Ultraviolet radiation (UV), including that from electric lighting, always has been a concern for art galleries, museums, etc., because of its harmful impact on artifacts.

Tuning the Light Spectrum To Improve Energy Efficiency (IAEEL 2/92) New research suggests that by tuning the light spectrum, light levels can be reduced without compromising visual performance.
