All-encompassing systems that control the lighting are not new, but again the fact that technology has continued to improve so rapidly over the years means the differences in today’s generation of controls compared to ones just a few years old is much better than before. Newer LED systems even offer faster startup times compared to older ones.
“We installed light-saving devices with the sodiums, there was a five to 10 minute lag-time between switching them on or off,” noted Kuehne+Nagel’s Kevin Greene. “So we weren’t realizing any particular benefit, and the switching on and off shortens the life of the lamps. The LEDs come on instantly and have no issues at all with switching.”
One only has to look at the developments in California to see that many people believe that integrated control systems are the future, since California’s Title 24 is set to require companies that want the benefits of an incentive from their utility companies to help pay for upgrades, must first have integrated control systems in their buildings. The trend of tying incentives to these advanced systems is something Digital Lumens’ Allison Parker claims “could spread across North America as other utilities follow their lead.”
The results speak for themselves
One common theme among the warehouse managers and companies that have chosen to spend the money and make the upgrade to LED lighting is satisfaction. In situations where a larger company installs LED lighting to just one or a few “test” facilities, the short-term results of the upgrade are so impressive that they typically make the switch company-wide.
“We’ve been so impressed with the performance and warranty of LEDs that we’ve begun retrofitting nearly all of our other facilities to improve efficiency, lighting efficacy and safety throughout our operations,” said Tim Schofield, Financial Controller at MMD Shipping in the UK. “I don’t understand why everyone doesn’t go LED. Between the energy and maintenance savings, and the tax incentives, the switch to LED fittings was a no brainer.”
Leading LED providers and products
For those looking to upgrade their facilities to an LED product or an LED system, following are some leading companies and products worth noting:
The Digital Lumens Intelligent LED System (intelligent LED fixtures and LightRules software) is now in more than 50 million square feet of industrial space worldwide. The actual fixture output, either 13,000 lumens, 18,000 lumens, or 26,000 lumens, depends on the light-level requirements, ceiling height, facility layout and fixture spacing.
LightRules is being used to manage the system, generate ongoing energy reports, and provide key data for utility measurement and verification. For Digital Lumens customers like Associated Grocers of New England (AGNE), as well as Ben E. Keith, ConAgra, and Mutual Logistics in France, the success these companies in the food supply chain have had with the LED System and LightRules software has been tremendous.
Dialight recently announced its new DuroSite LED High Bay and Low Bay products with a new long life power supply. With efficiencies up to 107 lumens per watt, the new power supply will be available in 17,000-3,800 lumen output fixture versions. This newly integrated solid state power supply is the latest innovation in Dialight’s rapid technology development program that has turned out a number of first-to-market technologies, including the first Class I, Div. 2 hazardous location certified high output LED fixture available with a 10-year full performance warranty.
This latest achievement in Dialight’s LED power supply development gives customers up to a 7 percent increase in efficiency across the high bay and low bay portfolio, according to Roy Burton, Dialight’s Group Chief Executive.
Orion Energy Systems offers a wide array of commercial LED fixtures in their ISON Class of LED products, including a Cold Storage High Bay fixture that offers optimum performance in cooler and freezer applications. With a 150,000+ hour lifespan and 173W high output, Orion’s Cold Storage High Bay fixture is providing savings that companies like US Foods can realize on their balance sheet.
