Standard street light bulbs would normally make use of the old bulbs which eat up a lot of energy, thus escalating the electric bills of city governments. Additionally, they do have waste problems should the eventually fizzle out. Add the both and you have a pretty serious problem as far as electricity expense, useful life and garbage woes, something which has been given an alternative in the form of LED bulbs.
Not only do LED bulbs last longer, they are more economical. They are sure to bring down the utility bills. The city of Los Angeles seems has obviously taken this into serious consideration retrofitting old street light bulbs with LED bulbs.
Over 141,089 street lights were changed to energy-efficient LEDs. Other cities have reportedly followed in the bulb swap initiative, great news for wiser city spending, not to mention greener ways of rendering needed illumination in public areas.
