WASHINGTON — D.C. is in the midst of modernizing its streetlights, converting mercury vapor lamps to LED lighting.

Some D.C. residents are carefully watching the District’s plans, hoping to keep streetlights warm and glowing instead of exceedingly bright and glaring.

“We are opposed to anything but 2,700-Kelvin streetlights, LED streetlights,” said Delores Bushong of Northeast, a member of the D.C. Street Light Task Force, a group of citizens concerned about the streetlights the city has been installing.

“The Kelvin is the color temperature, the warmness of the light — the lower the Kelvin, the warmer the light; the old-fashioned streetlights were more amber-colored,” said Rebecca Maydak, the Advisory Neighborhood Commission commissioner for Chevy Chase.

Some residents say 4,000-Kelvin lights installed by D.C. in some alleys in Chevy Chase between Broad Branch Road and 32nd Street meet the criteria for safety and security but the lights are way too bright.
