General service bulbs are inexpensive and readily
available in a wide variety of wattages and shapes.
They produce a yellow-white light that is emitted in
all directions, and are used in almost all types of
fixtures, including table and floor lamps, ceiling
fixtures, wall fixtures and chandeliers. They are
available in either a clear or frosted finish.

Federal legislation implemented in 2012 has increased
the energy-efficiency of standard incandescent bulbs.
Check with your ALA lighting showroom for more
information on these changes and the new types of
bulbs now available.
Reflectorized bulbs have a reflective coating inside the
bulb that directs the light in one direction, providing
better beam control than general service lamps. All
reflectorized bulbs are available in a variety of beam
shapes such as flood (FL), narrow flood (NFL), spot
(SP) and narrow spot (NSP).
Bulged reflector (BR) bulbs provide a soft quality
of directional light, and they are very common for
recessed and track lighting.
