The lighting bulb that offers the best value for money is the LED bulb. LED bulbs are highly energy-efficient, lasting up to 25 times longer than traditional incandescent bulbs and 10 times longer than compact fluorescent lamps (CFLs). According to the U.S. Department of Energy, LED bulbs use at least 75% less energy than incandescents and last 25,000 hours or more, which is equivalent to 22 years of continuous use at 3 hours per day. This longevity and energy efficiency make LED bulbs a cost-effective choice in the long run. While the initial cost of LED bulbs may be higher than that of incandescents or CFLs, the savings on energy bills and the reduction in bulb replacements over time more than compensate for the initial investment.
