To calculate the cost of running a 28-watt fluorescent bulb, multiply 28 by the number of hours the lamp is used and then multiply by the cost of electricity in your area. For example, if you use a fluorescent lamp for 5 hours per day, the daily cost would be: 28 watts * 5 hours * $0.12/kWh = $0.02/day. To determine the monthly cost, multiply ...
