Power Usage of Dimmed Incandescent Light Bulbs

Electronic dimmers have proven over the years to be an indispensable tool allowing poultry producers to precisely control lighting levels over the course of a flock. Though very effective in dimming incandescent light bulbs, many producers wonder if electronic dimmers are as effective in reducing lighting costs as they are in reducing lighting intensity. The fact is that power usage is does go down as incandescent lights are dimmed. The only problem is that the reduction in power usage is not pr...oportional to the reduction in light intensity. That is, a 50% reduction in house light intensity, doesn’t result in a 50% reduction in power usage.
