Light quality, levels, and duration are all extremely
important to broilers. Light is one of the major microclimate
factors for poultry production that influences
growth development and physiological functioning,
among others. Artificial lighting is extensively
used in raising commercial poultry. One of the major
functions of lighting programs, especially intensity,
is to influence growth rate of broilers, which allows birds to achieve physiological maturity prior to
maximal rate of muscle mass accretion. Most countries
around the world, including the United States,
have passed measures to phase out inefficient incandescent
(ICD) light bulbs in favor of more energyefficient
lighting alternatives
