Another Faulty LED Street Lamp

From the DeadSure app for reporting faulty street lighting.

Too early to make a judgement, but something tells me these new LED street lights are less reliable than the older sodium ones. Which makes sense, considering sodium lamps are simpler and purely electrical/electromechanical, whereas LED lamps have more working parts not moving parts, but semiconductorsthat can fail. I reported this one that I noticed tonight because the upper path in the Valley Park seemed dark. There may be a couple more not lighting, further out the road closer to St. Brigid's Well.

LED lighting theoretically has a lifespan in the tens of thousands of hours (30,000 to 40,000 hours). However, in reality it can be less than this because the driver electronics fails.
