Traditional roadway lighting uses high-pressure sodium light
sources, which provide high photometric efficacy.
West Caldwell, NJ, March 22, 2013 --(PR.com)-- Transforming existing inefficient fixtures into energy efficient lighting with improved efficacy and lower maintenance costs, MaxLite[R] has introduced the LED Post Top Retrofit Lamp as a replacement for traditional metal halide or high-pressure sodium light
The replacement lanterns, like those now installed in Thorntons Way, have a high-pressure sodium light

Phillips said savings from the switch would add up, noting that the older, high-pressure sodium lights
burn at 400 watts, taking up more power than the new-tech light-emitting diode (LED) bulbs, which are at 100 watts yet are much more brilliant.
However, we do know that Cree's LED production factory in China, which sends product to the U.S., is in line to be affected by tariffs. And while high-pressure sodium lights
are still the preferred lighting used when growing marijuana indoors, LED lights are (https://www.fool.com/investing/2018/05/11/contact-high-3-stocks-that-give-investors-secondha.aspx) expected to grow in popularity .
If the new system is instead compared to the savings from replacing the old units with 65,000 modern high-pressure sodium lights
at wattages of 150, 250 and 400W, the LEDs save roughly 34 million kWh and $2.4 million.
The LED installations also offer a 70% reduction in carbon emissions, compared to the old high-pressure sodium lights
"The big difference is that the [IES Type II medium distribution] LED luminaires produce a very even wash on the street and there are fewer hot spots than with the high-pressure sodium lights
," says Peiniger.
