Eco Trip: Episode 5 - Light Bulb
In this episode, David tries to find out if you can really affect the environment by simply changing a light bulb. In his quest for answers, David discovers that most of the energy in an incandescent bulb generates heat rather than light and looks into the future of LED bulbs, which can last 20 years while only using 1/30 the energy of a standard 60 watt bulb.
