There has been a transformation in the lighting industry it is moving from fluorescent to LEDs. The Internet of Things is helping the lighting industry. Increasing efficiency in lighting would save billions of dollars as lighting consumes 461 billion kWh of electricity in a year. LEDs can provide that efficiency, along with a number of other benefits. Energy efficiency is the main force behind the industry wide transition to LEDs. Initial cost of replacing may be high but in the long run it will save substantial amount of money. This problem of high initial cost has been addressed by companies like Philips, by offering lighting-as-a-service. Philips covers the initial installation costs. But offering lighting-as-a-service for something like a commercial building creates challenges as lighting is metered with other equipment in the building  and it is difficult to measure the amount of power light is actually consuming and making cost benefit analysis somewhat  speculative. All the problems associated with lighting can be addressed with the help of Internet. One way to solve the problem is to use Power over Ethernet (PoE) networks, where the Ethernet switch provides a centralized environment where metering and monitoring can take place. Read more at:
