Philips' latest innovation: flatten the lightbulb

 Philips has given the lowly lightbulb a makeover. Instead of the cylindrical shape synonymous with lightbulbs for the past 100 years, this new version is flat. 

The so-called SlimStyle is a 10.5-watt LED bulb that emits light at a brightness equivalent to a 60-watt incandescent. It has a lifespan of 25,000 hours, or about 22 years, and reduces energy use by 85 percent, Philips said in information sent via email. 

The bulb will be available on beginning Jan. 2, around the same time the final phase of the Energy Independence and Security Act, which places efficiency standards on 60-watt incandescent bulbs, goes into effect. 

The energy efficiency specs, which are similar to those found in many modern LEDs, are not what makes the bulb standout. It's the novel design. 

But this isn't design, for design sake. There's a purpose to the flatness. Philips flattened it to help pull heat away from the LEDs, eliminating the need for heavy aluminum heat sinks, which in turn, reduces the cost of bulb.
