UK local councils are being sold very expensive LED lanterns, to replace the HPS lanterns, in order to reduce the councils energy and service cost bills by 70%. I have developed a low cost alternitive useing a traditional lanter head that incorparated a HP sodium bulb, instead uses a LED screw in corn bulb, that comes with a life of 50,000 hrs. While the lantern casing has a life of 20 + years. If your council or country is looking to reduce its street/road lighting costs, contact me today
