PoE Lighting Gives New Life to Old Fixtures
Power over Ethernet and LED lighting join forces to salvage a unique lighting installation for The Waldinger Corporation’s headquarters.
Business Challenges
The central Iowa headquarters office of The Waldinger Corporation has always captured attention. The unique space has been showcased in architectural magazines, where the publications highlight features like exposed ductwork, high ceilings, and pendant lights. Although those lights may be a thing of beauty, they had become a bit of a headache. The lights were difficult to maintain, expensive to operate, and in need of replacement. The company wanted to change the lights to eliminate the headaches, while also protecting the contemporary aesthetics the lights provided.
At the same time, the design-build company had also been looking at intelligent lighting as a solution to add to their portfolio. Combining LED luminaires, sensors and software with Power over Ethernet (PoE) and an IP network, drives new levels of control, intelligence, and performance. As a low-voltage contractor, Waldinger was already installing PoE and IP networks for their customers. Adding PoE-based lighting to the networks was a logical next step. Waldinger President Tom Mass, however, is a firm believer in gaining some first-hand experience with a new solution before offering it to his customers. “I won’t put anything in a customer facility that we haven’t tried here,” Mass explains.
“Now we can show our customers how it works.
They can see it and experience it first-hand, and we can have confidence
designing it into their projects.”Tom Mass

The Solution
The solution was a retrofit of their existing lighting fixtures to an intelligent LED solution, powered by PoE, installed by their own team of low-voltage technicians.
Innovative Lighting, one of the first LED lighting manufacturers in the U.S., stepped in with their GENISYS PoE Lighting System, a solution that would meet Waldinger’s goals of keeping the existing aesthetic, while reducing both energy consumption and operating expenses. Innovative Lighting supplied LED components that Waldinger installed in the existing fixtures, converting the lights to a PoE-powered LED solution.
The large pendant fixtures are the primary light source for an open office area (15,000 square feet) that houses 30 people. Private offices form the perimeter of the space. To further test PoE lighting, Waldinger converted the lighting in four of those offices to the GENISYS PoE Lighting System, with four 2x2 troffers within each space. Occupants control the color and brightness of the lights to create a space where each worker is most comfortable and consequently, most productive.
Innovative Lighting’s GENISYS PoE Lighting System includes the GENISYS Intellidrive, a node that drives multiple lights, control, and sensors, all from a single unit. GENISYS software – an easy-to-use web-based interface – is also part of the solution, and enables control of fixtures either individually, or within a zone.
The PoE part of the solution is made possible by three Cisco Catalyst 3850 PoE switches and a PanGen Category 6 cabling system. General Cable GenSPEED 6 Cabling, terminated with Panduit TX6 PLUS Category 6 modular plugs, connects from the switch into each GENISYS Intellidrive. Panduit TX6 PLUS UTP patch cords then connect from each Intellidrive port to each fixture. According to Waldinger’s Matt Hall, project manager, the PanGen solution was their first choice for the cabling infrastructure, knowing it would deliver quality and performance at the right price.
Waldinger’s low-voltage team completed the installation and networking of the lights. “We did all the installation work ourselves,” Mass explains. “Our low-voltage guys pulled the cable. They cabled it right the first time and it worked right the first time.”
The PoE switches are housed in a rack in a controlled and conditioned area, which was selected based on its location relative to the length of cable runs needed for the lights. Today, that area is supporting only the PoE lights.
Business Benefits
Since switching to the PoE lighting system, Waldinger has realized several significant benefits:
• Financial savings: Wattage consumption has been cut by 60% monthly; The large pendant lights were previously about 400 W each; today, they consume less than 100 W per fixture; In addition, maintenance costs are improved, as bulbs do not need to be changed routinely
• Improved performance: The previous lights showed lines and shadows behind the light lenses, which are now gone; the refurbished fixtures boast an even glow and light output; The lights also deliver improved control and data collection
• Status quo: The retrofit allowed Waldinger to maintain the aesthetics of the office and the look of the light fixtures contribute to the space
• Lighting control: The GENISYS PoE Lighting System gives users control over the light color and brightness in their space to achieve a level that is unique and right for each individual; Because the pendant lights are in a communal space, the company tweaked the light levels and colors until they reached a level that all occupants could agree on; Office dwellers can change light levels in their office as needed depending upon the task they are working on, time of day, and outside light levels
Perhaps just as critical, is the experience the contractor gained by installing the PoE lighting solution in their own space. “Now we can show our customers how it works,” Tom Mass says. “They can see it and experience it first-hand, and we can have confidence designing it into their projects.”
With the success of the implementation in the current building, PoE lighting is being planned for inclusion in a new headquarters building that is on the drawing boards, which will accommodate Waldinger’s growing operation.
