Internet of Things (IoT) architectures are rapidly driving smart lighting technology, according to Gartner. The company predicts that smart lighting installed base is projected to grow from 46 million units in 2015 to 2.54 billion units in 2020. In 2014, 300 million to 500 million square feet of commercial space worldwide could be considered to have intelligent or smart lighting. This space is expected to double in 2015, based on the rapid growth in the smart lighting market.

Gartner defines smart lighting as a lighting system that is connected to a network and can be both monitored and controlled from a centralized system or via the cloud.

"Smart solid-state lighting in office buildings and industrial installations has the potential to reduce energy costs by 90 percent; however, achieving these costs takes more than just installing light-emitting diode (LED) lighting," said Dean Freeman, research vice president at Gartner. "To successfully achieve the lowest electricity cost, in addition to achieving safety and security and enhancing the office environment, lighting product managers at technology and service providers will need to implement five key strategic phases of smart lighting: (1) LED lighting, (2) sensors and controls, (3) connectivity, (4) analytics and (5) intelligence."

Implementing all five phases will ensure the highest level of success in reducing lighting costs and accelerating the adoption of smart lighting solutions. With these solutions, smart lighting providers will be able to leverage the impact of sensor data and analytics on the IoT.

"Smart solid-state lighting (SSL) costs are now at a point at which it is compelling to implement just the lighting," said Freeman. "Energy savings of up to 50 percent have been well-documented in many installations, and they are difficult to resist when replacing incandescent or high-intensity discharge systems in a warehouse. In a fluorescent installation, energy cost savings of up to 25 percent can be achieved, along with considerable savings in lighting maintenance."
