Trying to Solve the L.E.D. Quandary

Is there a workable business model for products that are built to last, rather than to fall apart? This is an idea that I explored here in July, in a story about the L.E.D. quandary. That quandary, in short: companies are making a good thing—light-emitting-diode bulbs that conserve energy and last for years—but they can’t make money in the long run from products that rarely need replacing. As global light sockets fill with L.E.D.s, century-old corporate titans are getting out of the bulb business even before “socket saturation” tips sales into a decline. The question remains whether any company has an incentive to make a product that is not designed to fall apart or become obsolete.
