Sharp's energy-efficient LED ceiling lights are hip to be square

If you live in Japan and are looking to lower your household electricity bill, you might have to empty your bank account first. Sharp recently introduced its new line of ELM-branded LED ceiling lights and the highly energy-efficient, square-shaped bulbs won't come cheap -- retailing between 35,000 yen (about $456) and 55,000 yen (about $717). Pulling inspiration from the LEDs used in LCD televisions, the company was able to achieve an industry-leading 81.3 lumens per watt for the smallest of its three designs, and an average life of 40,000 hours for the entire lot . The energy-sipping set of overhead bulbs come housed in an insectproof shell, offering over 100-plus ambient light settings, controllable via remote. You can snag these utility-friendly lights on August 27th, just don't complain at the checkout when you see the price -- we warned you. Peep the video explanation after the break.
