Expert: Retail lighting primarily LED by 2025
New York — By 2025, most retail lighting will be LED, or light-emitting diode, according to lighting expert Dr. Laura Priestwood Thompson, director of the TCU Center for Lighting Education, Texas Christian University.
“The majority of interior retail lighting in 2025 will be LED. This includes retrofitting and new construction,” Dr. Thompson told attendees as Chain Store Age’s 50th annual SPECS conference, which was held March 9 –12, in Grapevine, Texas.
Thompson said there are several advantages to using LED lighting. Although LED lighting is still somewhat expensive short term, in the long term it may still represent a more cost-effective investment than cheaper traditional lighting. In addition to various rebate programs, Thompson also cited the resiliency and power of LED lighting.
“You get a lot of lumens from a few watts,” she explained. “You get thirteen to fifteen lumens from 60 watts to 70 watts. This translates to high ROI from high efficacy. LED lights last 50,000-plus hours, so maintenance in changing them is lower. There is no mercury, lead or glass. They are durable and dimmable.”
Furthermore, Thompson said LED is becoming a mainstream lighting technology, meaning its cost will decline as time goes on.
“LED will be affordable for the masses in 10 to 15 years,” predicted Thompson. “Today, it is mostly deployed for artistic and creative uses Fluorescent lighting still exists. It has applicability in some places.”
Part of the expansion in retail LED lighting Thompson sees in the next 10 years or so is a vast increase in its use for exterior, as well as interior, lighting.
“By 2025, virtually all exterior lighting will be LED,” stated Thompson. “Right now, we have serious light pollution. Light is wasted shining up or on ‘light trespass,’ which is the uncontrolled glare or light from another property intruding on a property. If the property is another retailer they probably won’t care, but if it is residential or mixed use, they will probably mind.”
What's not discussed and never brought up from someone who comes from a "Lighting Education Center" is enlightening the users. What should be know is that all light sources have their pro's and con's. LEDs have their weakness's too. Heat being one of them, the other is getting enough usable light, in reality "Lumens" do nothing. This is hyped up term that is very hard for the average consumer to ever measure, and it's a number that is bloated by the LED manufacturer. We want to know usable light, how much it lights a surface or a room. I myself come from the electric sign industry and like everything else when it comes to retrofitting here is another "con" for LEDs. Most of the time the user will hear ROI in just a few years. Nothing is further from the truth, most of the time the reality is 20+ years, 40+ in a lot of cases. There is a big reason why big theme parks like Disney have gone from LED back to Neon. One of the biggest marketing terms is "LEDs" are 80% more efficient than T12 lamps, or Neon, or HID lamps. Again, false. When you measure usable light from LEDs vs say...Neon, or HO Fluor Lamps. The comparisons are like putting a penlight to a Maglite and saying the penlight is more efficient. True, it is but it's only putting out a fraction of light as the maglite and then claiming it's more efficient. It's also not fair to take money from tax payers in the form of a rebate and give it so someone who decides to use a lamp over their neighbor. That's stealing from Paul to give to Peter. This gives the false notion that LEDs are cost effective. What they just did was have government pick a winner, not the free market or consumer. LEDs should not be handicapped instead they should stand on their own merit. Mercury, Lead, Glass, just nothing more than environmental scare, or marketing material for the consumer to buy LED. Fact is most inexpensive LEDs are made in China. China has coal plants and it takes more energy to make LEDs than a Neon or Fluorescent lamp...MUCH more and that is putting more mercury into the air than what is contained in a mercury lamp which is all contained in a glass. So it's better to spend 150 watts to save 5 watts from another light source? Since the earlier marketing claims have not worked out so well especially in the electric sign industry where rebates have disappeared, Energy Efficiency in ROI has been debunked as a non factor and mercury is no longer a valid fear factor the new marketing point is "Light Trespass". This one really makes my chuckle. anything to sell I suppose. The reality is and another con for LEDs is, LEDs are angled pinpoint light that does not disperse very well and you need alot of it to light up a room or surface. Neon, Fluorescent, and incandescent lamps have a bigger advantage that they are 360 degree lamps. Most LEDs are 120. In short, just remember the basic laws of physics. You will only get back what you put into it. In other words, there is no magic wand or wonder product that gives you something for nothing. All light sources have their strengths and weaknesses, and they should be picked according to their application. There is NO wonder product that fits all applications. As a user, if that’s your intention, you will be paying more for something and get less back in return...that’s reality
Mexico’s Tiendas Soriana in Latin America’s biggest distributed solar deal
Monterrey, Mexico — Tiendas Soriana S.A. de C.V., Mexico’s second largest retail company, and Hanwha Q CELLS, a leading full-service solar power companies, announced a 20-year power purchase agreement for 31 megawatts (MW) of photovoltaic (PV) solar power at 120 retail locations across Mexico that will create significant long-term energy savings for Soriana. Soriana operates more than 640 grocery and department stores.
Hanwha Q CELLS will partner with Mexican developer and construction company ILIOSS to install rooftop and carport systems in Soriana’s stores in Mexico City and the states of Mexico, Jalisco, Querétaro and 12 others. Soriana will reduce a significant portion of their energy demand by using onsite solar power while fixing its long-term energy cost.
Hanwha Q CELLS will finance all 31 MW.
Hanwha Q CELLS and ILIOSS have already begun construction on the first seven solar systems in Baja California Sur, which will feature more than 12,000 high-efficiency, German engineered Q CELLS Q.PRO-G3 250 W panels to provide approximately 3.05 megawatts of combined generation capacity. Construction on all 120 sites is expected to be completed by early 2015.
“With this association Hanwha Q CELLS, Soriana and ILIOSS join forces to provide the most advanced technology to obtain clean energy at preferential costs. This project allows Soriana to meet both its sustainability and cost saving goals” said Aurelio Adán, CFO of Soriana.

Kohl’s honored by EPA for reducing greenhouse gas emissions
New York — Kohl’s Department Stores was honored by the U.S. Environmental Protection Agency for its efforts to reduce emissions linked to climate change. The retailer was recognized with EPA’s Excellence in Greenhouse Gas Management (Goal Achievement) Award for reducing carbon emissions by improving the energy efficiency in its stores and buying renewable energy and installing solar panels.
In 2009, Kohl’s established an absolute GHG reduction goal under EPA’s former Climate Leaders program to reduce its emissions by 100% each year from 2010 to 2012.
“To meet its goal, Kohl’s carried out a variety of GHG [greenhouse gas] reduction activities, including upgrading its stores’ lighting to lower-wattage and longer-lasting technologies and utilizing a centralized energy management system to help control, standardize, and eliminate energy waste,” the EPA stated. “Kohl’s also purchased renewable energy and carbon offsets each year of the goal period.”
Kohl’s was also honored for setting a new goal to reduce 100% of its absolute GHG emissions from its U.S. operations from 2013 to 2015.
“To help meet its new GHG target, Kohl’s will deploy new energy efficiency technologies throughout its stores including building controls, lighting, lamps, and HVAC innovation,” the EPA stated.
The retailer will continue to support renewable energy technologies through both on-site generation of solar and wind energy and the purchase of renewable energy
Kohl’s has been recognized with numerous EPA Energy Star and Green Power Leadership Awards during the past several years.
