The University of Georgia has been in the forefront of evaluating alternative lighting systems.  In their study, comparisons were made among conventional incandescent bulbs, compact fluorescent lamps, cold cathode and LED bulbs in poultry houses.  It was demonstrated that dimming compact fluorescent bulbs below 5 lux resulted in a higher rate of lamp failure than operation at non-dimmed levels of light output. This loss in life span could however be reduced by limiting the extent of dimming.  All bulbs exhibited a loss of light output ranging from 25% to 50% over ...
