The brand new site visitors lights you're seeing are made out of arrays of light emitting diodes (LEDs). These are tiny, purely digital lights which can be extraordinarily power efficient and have a really lengthy life. Each LED is about the size of a pencil eraser, EcoLight so a whole lot of them are used collectively in an array. The LEDs are replacing the old-model incandescent halogen bulbs rated at between 50 and a hundred and fifty watts. LEDs are brighter.

The light is on 24 hours a day, so it uses 2.4 kilowatt-hours per day. In case you assume power prices 8 cents per kilowatt-hour, it means that one visitors sign prices about 20 cents a day to function, or about $seventy three per yr. There are perhaps eight signals per intersection, so that's almost $600 per 12 months in power per intersection. A big metropolis has 1000's of intersections, so it may possibly cost millions of dollars simply to power all the visitors lights. LED bulbs would possibly consume 15 or 20 watts instead of 100, so the power consumption drops by an element of 5 or 6. A city can easily save one million dollars a yr by replacing all the bulbs with LED units. These low-energy bulbs additionally open the potential of utilizing photo voltaic panels instead of working an electrical line, which saves cash in remote areas. What are amps, watts, volts and ohms?
