The MathBy converting your existing fluorescent lamps with Kowa LED tubes, one may able to create an average 53-watt saving per fixture (assuming a standard fixture with three 4 ft. T8 fluorescent lamps consumes 88 W). This switch may save about 233 kilowatt hours (kWh) of electricity a year ― approximately a $25.60 utility cost reduction (based on an $0.11 kWh and 4,400 hours of operation). One may also anticipate less maintenance: a user of fixtures with fluorescent lamps may end up replacing old lamps and ballasts each year.
