New LED Lights on Inman Street. Let Us Know What You Think!

On March 3, 2011, the City replaced the lights on Inman Street between Massachusetts Avenue and Broadway with energy efficient LED light fixtures.  Working with consultants from PB Americas, the lighting has been customized for Inman Street’s sidewalk and street width and to minimize issues such as light trespass into front yards, based on feedback previously received during a month-long pilot LED study on Inman Street in 2009.  The LED lights now installed on Inman Street use almost 50% less energy than the high pressure sodium fixtures they replaced.

Over the last few years, the City has been exploring energy efficient sources for street lighting.  A 2010 Cambridge Lighting Study indicated that the City would like to further evaluate new luminaires emerging in the market before identifying the preferred LED luminaires for use in Cambridge.  While cost continues to be an issue, LED technology, which was adopted for the City’s traffic signals in 2003, has evolved greatly and is now considered more appropriate for street light applications.

Please let us know what you think of the light levels, quality of light, visibility on the sidewalk or any other thoughts about the new lighting on Inman Street.  Please send comments to Iram Farooq at or George Fernandes at
