The good news on LEDs are that these lights, quality-wise, are quite good and they put out enough light for a lot of needs. But there's no getting around the fact that LED bulbs for general lighting are a new technology that comes with a price premium. Home Depot's is priced at just under $40 and consumes 12 watts. A 40-watt equivalent from Lighting Sciences Group, which consumes less than 8 watts, costs just under $18.
