The answer depends on how you currently use your existing lighting. While 80-90% of the electricity supplied to conventional lighting is converted to heat and wasted, LEDs instead converts 90% to light, so a switch will always provide substantial savings. The amount you save instead depends on the wattage of your current lighting and the number of hours you use those lights each month. ECO Energy Management can provide you with a straight forward energy analysis of your business or home which will determine the cost, savings, and return on investment (ROI). Most businesses find the ROI for replacing old fluorescent and other types of commercial lighting to be 2 years or less.
