Up-front costs for warehouse lighting are easing, and options are expanding
From the outside looking in, warehouses can appear to be sleeping giants, with workers inside laboring under conditions unchanged since the first tilt-wall was lifted. But a look inside shows today’s warehouse operations today that are progressively more robust and dynamic in many way, including how lighting – the biggest draw on energy – is managed.
Around the turn of the millennium, high-intensity fluorescent lighting brought a significant number of benefits to warehouse environments, benefits that outshined high-pressure sodium and metal halide HID fixtures. Now, high-bay LED lighting is quickly gaining on or surpassing comparable fluorescent technology, as the overall cost for solid-state technology continues to come down. (And doing so without the high initial costs that once caused owners and operators to pause over LED installation or retrofitting.)
In addition to significant energy savings, today’s high-bay LED lighting provides high luminosity, high-temperature tolerance, long and reliable life, low-maintenance operation, compatibility with controls – and up-front affordability.
One example of a cost efficient LED luminaire for warehouse applications is the I-BEAM® LED fixture from Lithonia Lighting®, which was specifically designed as a one-for-one replacement of fluorescent and HID systems. This high-performance, high-quality, configurable LED luminaires pays for itself in as little as two years when compared to fluorescent lighting counterparts. And, as with most LED lighting products, the I-EAM LED fixtures pays dividends for years to come by way of a low total cost of operation.
Controls and daylighting take occupancy-cost savings even further
The I-BEAM LED luminaire is also an example of how LED fixtures can be integrated with controls technology to maximize the return on a high-bay-lighting investment for the modern-day warehouse. The luminaire can be equipped with an occupancy sensor, photocell, nLight® or nWiFi™ controls, devices that are factory-installed and that require minimal labor to set up during fixture installation.
An advanced energy-efficient warehouse goes a step further to combine lighting systems such as the I-BEAM LED and the compatible controls with daylighting. Daylighting products from Sunoptics®, for example, provide tremendous cost savings by harvesting the light of the sun. By integrating high-performance prismatic daylighting with a lighting-control system, building owners can create the optimum level of energy efficiency while creating an environment of high productivity for the workers using the space.

Acuity Brands is pleased to add Easyl™ Touch to our family of DMX RGB control products. Easyl Touch improves control of RGB LED luminaires with an astronomic time clock, intuitive scheduling and remote station support. The color LCD touch screen allows users to modify preprogrammed shows to create subtle or dramatic eye-catching lighting effects. Easyl’s intuitive user interface and show preview bar invite users to play.
The Easyl Touch is ideal for:
• Retail displays
• Building facades
Easyl Touch is compliant with DMX512-A, which means it can work with virtually any DMX luminaire, including those with RDM support. Control, programming and maintenance of DMX color-changing lighting have never been easier. Pairing Easyl Touch with the Parata flood from Winona Lighting or other DMX RGB luminaires from Acuity Brands ensures the highest level of performance and quality from a single source.
- Astronomic Time Clock: starts shows, plays a color, triggers a rainbow, or turns off based on time of day or offset from sunrise and sunset
- Battery Backup: keeps clock running for 10+ years in case of power failure
- Accessory Control Stations: hard button or touch screens station allow control from up to 3 locations

Lighting Survey Tool Measures Occupant Satisfaction
Building owners acknowledge the importance of lighting quality, but decisions are usually made solely on the bases of cost. Part of the problem is that while individual elements of lighting quality are definable and can be expressed using metrics, an overriding lighting quality metric remains unattainable.
A new free tool from the Pacific Northwest National Laboratory (PNNL), launched in association with the Department of Energy’s Commercial Lighting Solutions program, seeks to define lighting quality in office buildings. Funded by the Department of Energy, General Services Administration, National Electrical Manufacturers Association and the Lighting Controls Association, the Light Right Survey Tool enables building owners to survey office lighting workers about their lighting equipment, level of satisfaction, and preferences.
The result is a metric for lighting quality—as expressed by the people who use the lighting.
The Light Right Survey Tool uses 50 questions to profile respondents. It identifies the type of lighting in their workspace, how satisfied they are with various aspects of their lighting, and their preferences. The questions were developed by people with a high level of knowledge in lighting—including TED’s lighting columnist Craig DiLouie—but geared toward people with very little knowledge.
The results can be used to identify problem areas for corrective action, measure the effectiveness of lighting upgrades, justify investments in higher-quality lighting to the building owner, facilitate communication across stakeholders, and support choices that produce higher satisfaction. By studying the results, the owner will be told by the people who actually use the lighting—workers whom the owner wants to see satisfied and productive. Distributors can use the results to justify various lighting options that not only save energy, but may also improve lighting quality.
The survey begins with general questions about the type of work performed and asks respondents to describe their personal workspace, type of computer screen, availability of windows, etc. It then goes on to ask further questions about the lighting environment, such as:
To what extent can light levels from your overhead lights be adjusted?
What type of shading system do you have to control the amount of daylight entering your windows?
Are you satisfied with your ability to control your overhead lighting?
Are you satisfied with your ability to control your task lighting?
Are you satisfied with your ability to control your window shades or blinds?
Is your work surface is evenly lighted without very bright or dim spots?
If the majority of respondents indicate that there isn’t sufficient light levels for tasks they perform, this information can be used to determine which fixtures to include in an upgrade project.
Acuity Brands has an extensive portfolio of lighting fixtures, giving building owners and lighting designers a wide range of options to best meet the occupant needs that are indentified in this survey. One example is the Lithonia Lighting AL LED, which provides superior light quality and color consistency. When the nLight™ lighting control system is included in the solution, the end result is a lighting system that provides quality lighting while reducing energy use.
Survey results that detect insufficient satisfaction with the availability of natural light could indicate that a Sunoptics High-Performance Daylighting Solution should be included in the project. Sunoptics patented signature series prismatic system provides greater daylighting with no hot spots, glare, moving parts or UV damage. When combined with Acuity Brands lighting and control systems, building owners and designers can provide one of the most cost-effective, aesthetically pleasing lighting environments available.
