Energy savings were even greater when comparing the 130-watt LED light with the 250-watt conventional version.
The 130-watt LED light consumed 40, 46, 26 and 31 watts in four readings, about half as much as the 250-watt predecessor: 93, 78, 62 and 67 watts consumed.
“While we are finding significant energy savings in this initial analysis, we will need a full year of data to perform a more thorough analysis,’’ Xcel said.
The firm said it found largely positive reactions in a survey of 952 West St. Paul households. About 150, or 16 percent, were aware of the new lights.
“Of those aware, the sentiment is very strong: Nearly nine out of 10 customers said they were satisfied with the LED street lighting and 77 percent said they were highly satisfied. ... Almost two-thirds of the customers surveyed see the new lighting as enhancing the appearance of their neighborhoods (64 percent) and making their neighborhood safer (61 percent).’’
Zanmiller said a few residents were initially unhappy with the additional light the LED lamps produce. Xcel either redirected the light or put up screens to shield windows and yards.
