Don't fluorescent lights flicker and buzz? |
New fluorescent lights provide steady and even lighting with no
buzzing or flickering. The new T8 lights use electronic ballasts,
rather than the "magnetic" ballast old fluorescent lights use.
Magnetic ballast lamps operate at about 60 cycles per second, which
some people perceive as a flicker. New electronic ballast operate at
about 24,000 cycles per second, eliminating the flicker. The
"buzzing" is also gone, since there is no magnetic transformer
core to vibrate at the lower frequency.
