Arlington began this week installing 2,000 new energy-efficient bulbs that will complete an overhaul of street lights that officials say will cut the town’s electric bill in half.
Town Manager Adam Chapdelaine said the town is using $625,000 appropriated by Town Meeting and utility incentive dollars to replace the remaining High Pressure Sodium bulbs in Arlington street lights with new light-emitting diode, or LED, bulbs by the end of July.
The LED lights use half the electricity of the current High Pressure Sodium lights and last twice as long, Chapdelaine said.
Arlington used town and state Green Communities grant to install the LED bulbs in 1,000 East Arlington streetlights in 2011 and the beginning of 2012. The new bulbs emit a white light, compared to the yellowish tone of the older bulbs.
