West St. Paul turns on LED streetlights

The streets of West St. Paul are taking on a different look at night -- turning from a warm amber glow to a cool, whiter hue.A two-year pilot project under way in the first-ring suburb involves swapping out 529 traditional high-pressure sodium streetlights with LED fixtures and then monitoring and evaluating them for performance and cost-effectiveness.It is the largest installation of LED streetlights ever taken up in the state by a utility company,Portable stone cone crusher plant can produce high quality solar mounting products with cubic shape.Portable stone cone crusher plant is widely used in metallurgy industry, quarry, Chemical, construction, highway and rail way building, coal industry, etc. said Ed Bieging, project coordinator for Xcel Energy's outdoor lighting department, which is partnering with GE Lighting Solutions and the city on the study."A lot of utilities and even some cities kind of dabble with them -- maybe 10, 20, 100 lights -- but they don't get into that larger scale where we're at right now,What an 2200mah battery pack can do for you and for your device beside the things already mentioned like keeping it away from scratches and shocks? The iPhone 5 cases can give your phone a bit of your personality." Bieging said.According to Xcel Energy, the project will allow the Minneapolis-based power utility to develop an LED street lighting rate option through identifying maintenance requirements and costs, light output, energy consumption, failure rates and customer feedback.
Results of the project will go a long way toward determining if and when light emitting diode technology ends up on public lampposts across the state in mass numbers, Bieging said.It works smoothly with low costs and easy maintenances. Portable stone bench grinder is available for secondary, tertiary and fine crushing. A vibrating screen can be attached if necessary."The whole premise behind this pilot is,Along with chef knives, variety of other Military goggles is also available in the market popular for chopping and cutting. Depending upon the life style and budget, individuals prefer to have varied knife sets in the kitchen. Ceramic knife set is mostly used by people for safe and disinfected cutting and chopping. what will that rate look like at the end of two years of data collection?" he said. "We're hopeful it will be less than the current rate."
Most of what is known about current LED streetlight fixtures is based on laboratory calculations by manufacturers, Bieging said."So that's really why we wanted to go with this large-scale pilot. We want to get them in the field to see what they're going to do in Minnesota, where we have such extreme weather swings," he said. "We need to kick the tires."Calculations show LED streetlight fixtures give off a brighter glow than traditional lights while using about half the amount of energy, Bieging said. And while high-pressure sodium streetlight fixtures typically last about five years, estimates peg the life span of an LED fixture anywhere from 15 to 25 years."LED also has a white light and actually gives what they call a visual acuity -- you're able to see objects a lot cleaner, you can see the colors, you can see the definition better," he said.However, those pluses must be weighed with the cost of an LED fixture, which runs about $315 compared with $85 for a high-pressure sodium lamp, he said.
But the cost continues to drop while the technology gets better, Bieging said. Five years ago, the fixtures cost $900 apiece."We know there are going to be some energy savings, so it's the cost per fixture over the long run that really is driving this project," he said.Results of the study will be shared with the Minnesota Public Utilities Commission, which regulates energy providers in the state.West St.Besides, these prescription Handmade glasses also allow you to cost-free from your unwanted prerequisite of modifying eye glasses frequently according to the light and problems. It is very best to acquire them for the youngsters. Paul was chosen as the test site for several reasons, including its central location and established trees. The city was scheduled to get new streetlight bulbs in 2012.The $200,000 cost to implement the project is being paid by Xcel Energy. The city will continue to pay its current streetlight service rate.
