An anonymous reader writes: One of the most exciting aspects of the advent of LED lighting has been the chance for companies to take unique approaches to how they want to solve the challenges presented by the shift in technology. Now 3M, a company not generally associated with light bulbs, has entered the LED market with its own novel design. The company developed an LED bulb that was able to take advantage of its experience in edge-lit TVs and LED backlighting. Rather than using a more conventional design, the Advanced Light — the company’s first home bulb — uses lightguides in order to distribute the light generated inside. This comes with some interesting advantages, most importantly a design that looks a lot like a conventional incandescent bulb and one that casts a similar light pattern.
