BOSTON--The Northeast Sustainable Energy Association every year puts on the Building Energy conference here, where there are green building products on display. One of the few new products at this year's event last week were these LED bulbs for the home. On the far left is a 60-watt equivalent from Philips and on the far right is a downlight from Cree. LED bulbs are far more efficient than incandescent bulbs and more efficient than compact florescents. They are also supposed to last 15 to 25 years. The problem? Cost. The Philips bulb costs almost $40. Costs are coming down, though, and there are some rebates available.
