LED technology continues to rapidly expand and advance, and we at Twin Supplies are here to help you make sense of it all! One of the most crucial components of the new generation of LED fixtures are the advanced lighting controls, including occupancy sensor and daylight harvesting capabilities. Local utility companies offer significant rebates for upgrading to lighting fixtures with advanced controls, and Twin Supplies is always ready to help. Check out some useful information below relating to these technologies and how they can benefit your bottom line!
The first advanced lighting components we will analyze come from Philips, and they are known simply as the EasySense “Sensor 200” line. The SNS200 module is used used on 2×4, 2×2, and 1×4 lay-in troffer style fixtures, as well as on surface mounted strip lights. The second version, called the SNH 200, is used on highbay fixtures in high ceiling settings.
Both sensors have the same functions and capabilities, the only difference is the height ranges in which they can be used. The first function of both is occupancy sensing, and this ensures that fixtures will turn themselves on as soon as they detect occupancy in the room using their PIR sensor function. Then, after there is no more movement present in the room for any programmed amount of time between 30 seconds and one hour, the fixture will dim down to a preset background light level of 20%, or any other desired percentage you may choose. After another chosen time of 30 seconds to 3 hours after that, the fixture will then completely shut off.
The second function of the Sensor 200 is daylight harvesting. These photometric sensor capabilities will dim the fixtures according the amount of light that is ambient in the room. By detecting how much natural sunlight is being let into the area, the sensor is able to reduce the amount of power being drawn from the fixture while also maintaining adequate light levels. As the day goes by, the system detects when there is inadequate sunlight remaining to supplement the lighting, and it returns the fixtures to full power. As we understand that some areas require constant light operations, for example manufacturing plants that operate 24/7, both functions can be tweaked if need be, depending on the specifically grouped area where they are being implemented. They can also be task tuned in a variety of ways to achieve the light level and sensor functions needed.
The aforementioned sensors can also be meshed together through a near-network using a module from Zigbee, which allows for convenient, wireless control of grouped lighting fixtures. A sensor is mounted on each fixture to achieve this networked connection from fixture to fixture. Zigbee is a low-cost, low-power, wireless mesh network standard targeted at devices in wireless control and monitoring applications. The Zigbee product delivers low latency communication, which allows the grouped lights to “talk” to each other. For instance, when you walk into a room, the first light that detects occupancy will tell all the other lights of the occupancy instantly, and all lights in the room will come on at once. Likewise when all sensors detect no occupancy after the set time (factory Setting is 15 minutes), they in turn tell all the other lights to first dim down to their background light level (factory Setting is 20%), and then turn off fully after another set period of time (factory setting is 15 minutes).
The EasySense sensor operates with the established Xitanium SR driver standard to make a simple two-wire connection between sensor and driver,thus eliminating the need for multiple components and auxiliary devices. There is no need to pull low voltage dimming wire, and no need for CAT-5 cables. The result of this pairing of EasySense sensor and Xitanium SR Driver is a cost effective and easy to design solution ideal for energy savings, and lighting and control improvements. An intuitive app operated from a cell phone makes configuration and commissioning during and after installation fast and easy using Philips field apps.
Here at Twin Supplies, we have control specialists who have been working with these systems since the very first generation and will get the light task tuned to the exact unique needs of your business. Contact us today to learn more!

To our valued Twin Supplies clients, vendors and business partners,
As part of our commitment to your health and safety, we are continuing to closely monitor the COVID-19 situation and are taking extra precautions in order to ensure the healthiest possible environment for all. As you may have heard, Illinois Governor J.B. Pritzker issued an executive order on March 20th, asking all citizens of the state to shelter in place. In this order, the governor also made distinctions regarding essential businesses. Twin Supplies, within the guidelines set forward by the governor, is continuing operations so that we can support other essential businesses with the products and services they require to remain operational.
While we are currently maintaining a “no visitor” policy at our office, we continue to remain available at any time via e-mail, phone, or in person with limited contact, and are working remotely to ensure all projects and orders continue to move along as smoothly as possible.
We realize that every entity, whether in the public or private sector, is going through an unprecedented time right now, and we just wanted to remind you that our team continues to be available for any of your lighting needs, no matter how big or small. Please accept our sincere thanks for your continued patronage and business as we all work through this challenge.
Find out how you can still take advantage of ComEd’s LED streetlight replacement bonus program and get as much as 2.1 times the regular ComEd energy rebate. The offer only extends through the end of 2017 and available on a first come first serve basis!
This job was completed at Korex Corporation, a manufacturing facility located on the south side of Chicago. This project focused specifically on the installation of energy efficient lighting in their storage warehouse. The total project cost was $23,447, with the company receiving $18,698 worth of rebates from the ComEd Energy Efficiency Program. Korex wound up paying only $5,541 out of pocket for the total project – less than 25% of the total project cost!
This simple project consisted of replacing Qty (48) – 400W existing Mercury Vapor fixtures with Qty (33) Delviro Titan 160W LED highbay fixtures. The Titan LED fixtures were a perfect solution for this application because they perform better in high, open areas and provide optimal lighting for vertical surfaces, such as shelving. Furthermore, since this location is primarily a storage facility, the occupancy sensor was an ideal way to deliver even more energy savings. For example, the fixtures turn on once a customer enters the area, remain on while they source the material and deliver it to another part of the factory. After 30 minutes of no activity, the lights in the storage area shut off automatically, saving additional energy and reducing operating costs even more.
In the end, Korex reduced their monthly electrical charge from $900 to $300 saving the company $600 a month in just electric charges! The payback on this project is a little over 9 months. Also, the Delviro fixtures used in this project came with a 10-year warranty and are virtually maintenance free for the duration of the life of the fixture. “These provide incredible maintenance savings!” Jim Barca reported, “[the new lights] brighten my day every day, and I am so happy I am saving money and not burning unnecessary energy.”

Twin Supplies recently completed an energy upgrade project at Holy Cross Church in Chicago, IL. The high ceilings and beautiful cathedral-like structure made replacing incandescent bulbs in the ceiling a costly and time consuming ordeal.
Twin Supplies recently completed a lighting renovation project of the main gym and workout areas at the former Chicago Bulls practice facility in Deerfield, IL. The project was paid for in part through the Smart Ideas for Your Business incentive program offered by ComEd, known as the Small Business Energy Savings Program (SBES). The balance of the project was paid for by the new owner of the facility, Event Creative of Chicago, IL.
According to Mr. Sean Cannon, co-partner of the New Venue One North Shore as the facility will now be known, “We’re very happy with the new look of the facility. I’m really glad (Twin Supplies) pushed the project through with us here at Event Creative.”
Replacing the existing metal halide lights in the gym and workout areas with LED “Spun Bays” from Lumecon Corp. in Farmington Hills, MI reduced the wattage in those areas by 83% (50,760W to 8,460W). The total project cost was $54,732 with incentives from ComEd totaling a whopping $33,840 and resulting in a total out-of-pocket cost for Venue One of $20,892. Estimated annual electrical savings are $14,545 making the simple ROI of this project just 1.4 years or a little over 16 months.
As estimated by the project workbook provided by the Smart Ideas for Your Business incentive program offered by ComEd, the environmental benefits from replacing 47 gym lights with LED luminaires is the equivalent of 28 less cars driven per year; or 15,078 gallons of gasoline saved; or even 18.4 tree seedlings grown for 10 years – truly an environmentally friendly event if there ever was one.

The average kilowatt rate in the USA is ten cents per kilowatt hour and climbing. If, for example, you leave a 100-watt bulb running continuously (730 hours a month), and you pay10¢/kWh, your cost to run the bulb all month is 100 x 730 ÷ 1000 x 10¢ = $7.30. Per Bulb. What if you could get the same amount of light but only use 18W, reducing that $7.30/per bulb to 1.31!
