This document compares the performance of IBTS LED street lights to high-pressure sodium (HPS) street lights. Key points include: - IBTS LED lights have higher efficiency, illuminance, color rendering index, and lifespan than HPS lights. They also use less electricity. - Specifically, IBTS 115W LED lights use 130W per hour compared to 295W for 250W HPS lights, resulting in 50.8% lower electricity costs. - The monthly electricity costs per IBTS LED light are RMB39.9 compared to RMB90.3 for HPS lights, showing significant savings with LED.
