Yes, LEDs can be bright and pleasant

Even though they have been a symbol of brilliant thoughts since 1879, the incandescent light bulb may not be such a bright idea after all.  With the average bulb using about 60 watts of energy, or .06kW(kilowatts) per hour and operating 8 hours a day, it comes out to use about 175.2 kW of energy a year. Multiply that by the 45 light bulbs an average American family has in their house hold to get a staggering 7884kW of energy spent on light bulbs alone.
