Fluorescent
Lighting
Fluorescent lamps emit diffuse light from long glass
tubes. This characteristic of diffusivity has
enabled fluorescent fixtures to dominate the market
for lighting commercial, institutional, and
industrial spaces with ceilings less than 15 feet
high.
In recent years, however, the emergence of
more intense and efficient fluorescent lamps coupled
with specially designed reflecting fixtures has
enabled fluorescent systems to break through the
ceiling-height barrier and compete directly with
HID
lamps in
high-bay applications.
High-bay Fluorescent
advantages include:
-
Reduced energy consumption (50% or more)
-
Excellent
uniformity of illumination
-
No work time
loss due to momentary power interruptions
-
Better
color rendering, full color spectrum lighting
-
Redundancy through multiple lamps per fixture
-
Superior maintained lamp output over lamp life
-
Available lighting controls and dimming options
-
Improved productivity, plant safety and worker
morale
-
Reduced cooling loads
-
Reduced maintenance costs
The lamp life for fluorescents is about the same as
for HID lamps, but fluorescents may have a slight
advantage when you factor in their lower lumen
depreciation rates. There may also be a slight
convenience advantage for fluorescent fixtures when
it comes to changing lamps: HID lamps need to be
replaced immediately when they fail, but when a
fluorescent lamp fails, several other lamps in the
fixture will still be working. |
