Light Bulbs - A Short History

Used in my review for the Philips Ambient LED light bulb: www.lifeisaprayer.com/review/miscellaneous/philips-dimmab...

 

From left to right: A standard 100W incandescent, an older GE spiral CFL (13W/60W equivalent), a Philips AmbientLED bulb (12.5W/60W equivalent), a Sylvania micro-mini CFL (13W/60W equivalent), and a Sylvania Halogen bulb (43W/60W equivalent).
