Twisthdm

The Twisthink team developed Limelight, an outdoor lighting control system, with the belief that its idea could revolutionize the lighting industry. This IoT lighting solution maximizes energy savings, streamlines maintenance, enhances safety and reduces the total cost of ownership.

Challenge

On average, there are 6.5 billion kilowatt hours wasted on parking garage lighting, which amounts to over $2 million per day and $730 million annually. This energy is wasted because lighting, particularly in parking garages and parking lots, are being left on all 24 hours of the day. The Twisthink team saw an opportunity to reduce energy costs and maintenance costs by only using light when, where and to what degree is needed. We also saw an opportunity to create a safer and most sustainable environment. 

“LMELIGHT HAS ENHANCED CAMPUS SAFETY, PROVIDING US WITH POSITIVE ENVIRONMENTAL CHANGES AND SAVINGS THAT HAS PROVIDED A QUICK R.O.I.”

Solution

Limelight is a sustainable and safer way to produce more efficient lighting, it combines high density mesh (HDM) wireless and advanced luminaire technologies that allows two-way communications to continually monitor and adjust parking garage light levels.

Connected Technology 

The Limelight technology combines high density mesh (HDM) wireless and advanced luminaire technology that allows two-way communications to continually monitor and adjust lighting levels. It allows users to light harvest both day and night. Facilities are “perfectly calibrated” throughout the daylight hours, and set to low light output until activity is detected in the evening hours. Users also receive monthly energy savings report to evaluate how their facility is performing and can make changes accordingly through the Limelight dashboard. 

User Experience

User Experience

With a motion sensor in every fixture, Limelight safeguards the entire structure and warrants that if a customer enters or exits the garage at anytime, the system will light the way. Fixture grouping allows an entire row or floor to illuminate on demand once motion is detected at entry point. As cars leave the facility, the floor path the vehicle travels will light up well ahead of time, escorting the patron through the facility. Patrons experience a seamless and 100% uniformly illuminated space, unaware of the behind-the-scenes controls. Facility managers and owners also benefit from the flexibility of Limelight by being able to control the luminaries remotely from any location through the Limelight website.

Energy Cost Reduction

Year ROI or less

Only Limelight’s IoT lighting controls can provide daylight and nighttime harvest for any fixture, report on the status of each fixture, provide real-time information on lighting status, and track facility activity overall delivering an ROI in less than 3 years. Limelight is a key asset in minimizing maintenance costs both labor and general upkeep. Limelight has saved its users an average of 70% in energy costs and continues to bring value to clients across North America in the applications of: parking garages, site and area lighting, parking lots, warehouses, manufacturing, exhibit halls, convention centers and even outdoor car dealerships.
