Dialight delivers light relief for cold-store workers

As anyone who has ever had the misfortune to have to work under HID lighting will testify, working in poor lighting is no picnic. It’s not just a question of personal preference either. Colours look wrong; it’s difficult and tiring trying to make out detail on job sheets or packing lists and the pervasive gloominess seems to make every task a slog. Combine poor lighting with -20 degree temperatures and you’ve got some idea how difficult life was for the workers at a cold storage facility we visited in Japan recently. That is, before Dialight came to the rescue.

Dialight Debuts Next-Generation StreetSense® LED Roadway Sign Light

Latest Innovation Cuts Energy Consumption by 30% over its Predecessor; Flexible Mounting Options, In-Line Connectivity and Zero Maintenance Make New 70W and 40W Units the Most Cost Effective, Versatile Solution on the Market

Farmingdale, NJ (January 16th, 2013) – Dialight (LSE: DIA.L), the innovative global leader in LED lighting technology, today unveiled its next-generation StreetSense® LED Roadway Sign Light, delivering the industry’s most efficient and versatile lighting solution for roadway and infrastructure signage. Offering unprecedented flexible mounting options and years of maintenance-free illumination backed by Dialight’s full-performance 5 year warranty, the new StreetSense fixtures are ideal for both new construction and retrofit from existing HID metal halide, high-pressure sodium and phased-out mercury vapor fixtures.

The new StreetSense Roadway Sign Light is available in two versions. A 6,000-lumen, 70W unit used in multiples to illuminate signs larger than 14 x 14 feet provides exceptional cost savings and a greener lighting solution by consuming 30 percent less energy than previous generation fixtures. The 4,000-lumen, 40W version, used in multiples on signs equal to or smaller than 14 x 14 feet, provides even greater energy savings with its impressive 100 lumens per watt performance.

In addition to superior energy efficiency and cost savings, the newest editions offer both top- and bottom-mount flexibility with a pivoting head for more precise light placement on the sign. Weighing in at less than 20 pounds, each unit also features two terminal blocks which allows for through-hole, in-line connectivity and the ability to wire one fixture directly to another in daisy-chain fashion. This simplifies installation by eliminating the need for dedicated wiring for each individual fixture. A slip fitter mounting accessory enables the units to be affixed to either a pipe or a plate.

“Typical roadway sign lighting is costly to operate and a major drain on maintenance resources, not to mention the traffic headaches caused by the frequent bulb changes required of HID lighting fixtures,” said Roy Burton, Dialight’s Group Chief Executive. “This new StreetSense LED fixture resolves all those challenges, slashing operating and maintenance costs by nearly 75 percent compared to traditional 100-250W HID sources and freeing up precious manpower for other more important projects.”

Unlike conventional fixtures that fade over time, the Dialight StreetSense LED Roadway Sign Light delivers longer-lasting, high-visibility cool white light with more than 70 percent lumen maintenance and a minimum of 20 footcandles output after 60,000 hours. Dialight’s emphasis on light quality is also exemplified with uniformity ratios of 6:1 or better. Compared with conventional fixtures, “hot spots”—or islands of light surrounded by darkness—are no longer a problem.

Each unit comes standard with a robust 6KV surge protector, and Dialight is the only manufacturer to offer an optional 10KV and 10KA surge protector for greater resistance against lightning strikes or high-voltage/high-amperage spikes. The ruggedized fixtures are highly resistant to shock and vibration up to 3G, withstanding even the heaviest truck traffic on overpasses and bridges with Caltrans QTL specifications pending. And, unlike conventional lighting that’s prone to long warm-up and re-strike periods, especially in cold weather, the Dialight LED StreetSense units offer instant-on capability and perform exceptionally well in any temperature from -40°F to +165°F.

The Dialight StreetSense LED Roadway Sign Light is designed to meet IEES RP-19-01 and CSA 1598 22.250 roadway sign lighting standards, is IP66 rated and UL-1598 compliant for moisture/wet locations. It also meets the ASTM B117 salt/fog standard, having undergone 3,000 hours of salt spray testing.

How’s this for truly shock-proof LED lighting?

Dialight’s LED luminaires undergo a test on a deck shock machine that simulates the effects of an explosion on ships decks and bulkheads. Just look at the punishment they take from 35G and 70G stress and the lights don’t even flicker!

First you’ll see the test in real time, then at half speed and finally at 25 frames a second. It’s the final sequence that really shows what they’re going through. Video © QinetiQ Ltd 2012.
About the Deck Shock Machine

This is an essential test for equipment on naval vessels. The Deck Shock Machine simulates the shock experienced by equipment on ships decks and bulkheads removed from the ships bottom. The nature of the pulse is that of a damped sinusoidal wave with a frequency, depending on equipment mass, of between 23Hz and 27Hz.

The test took place at the Shore Based Shock Testing Facility at QinetiQ’s Defence Evaluation and Research Agency (DERA) at Rosyth Royal Dockyard whose principal function is the simulation of non-contact underwater explosions using shock machines.

The new 300,000 square foot Diamond Pet Foods facility in Ripon, Calif. went online in May 2012 with more than 500 high-efficiency, Class II Div 2 LED fixtures by Dialight, the innovation leader in industrial and hazardous location LED lighting. Through combined energy and maintenance savings, the company expects a full return on its investment in less than two years and will benefit from improved visibility thanks to the clear, white light of the Dialight LEDs.

The Challenge

A leading manufacturer of super premium, nutritious and natural pet foods, Diamond Pet Foods is a family-owned business with more than 40 years’ history of providing the highest-quality pet foods at an affordable price for dogs and cats of all ages. Thanks to its rigorous 151 Checks ingredient and product quality system, the brand has become the choice of top breeders, kennel owners and families worldwide.

Planning to construct a new manufacturing facility, the Missouri-based company had been so impressed with the work ethic of employees at its Lathrop, Calif. plant, Diamond chose neighboring Ripon, Calif. for the new site, just 30 miles away. The 300,000 square foot plant would be a Class II Div 2 facility as dictated by its raw materials, which arrive in powder form, are extruded into a pellet and then dried through an oven.

Aiming to minimize energy consumption and achieve more sustainable operations at the new facility, the company installed solar panels designed to provide roughly one-quarter of the electricity to power the building.

The manufacturing environment posed a number of lighting challenges. First, the company needed an ultra-energy-efficient system to reduce consumption and fully leverage the benefits of its solar system. Second, they required Class II Div 2 certified fixtures that would offer safety and reliability amid the high-vibration and dusty conditions. Ambient heat and humidity was also an issue, driving a need for lighting that would safely withstand up to 120°F and high humidity in the extrusion areas. With many hard-to-reach and low-clearance areas near process equipment, Diamond also needed dependable fixtures that offer longevity, low maintenance and ease of installation.

Finally, from an economic perspective, the company required a payback period on the project of less than two years in order to gain corporate approval.

The Solution

All things considered, LED lighting was the natural choice. Diamond consulted with Nelson & Sons Electrical, the company’s electrical service partner for more than 15 years and a specialist in lighting and electrical needs for the food processing industry, to help specify the best solution. Diamond began with a trial of 16 Dialight DuroSite High Bay LEDs in the receiving area, prior to the facility coming online.

Satisfied with what they saw, the company gave the green light to outfit the entire facility, including 304 2-foot and 4-foot LED Linear fixtures, 145 LED High Bays and 89 LED Area Lights, for a total of 538 Dialight LED fixtures.

The Results

The low profile of the Dialight LED fixtures enabled mounting in areas that would have been difficult with other bulky conventional lighting fixtures, and the company can expect to use at least 50% less energy compared to other options.

Not only did the Dialight products offer the rugged durability Diamond required, but each fixture is also backed by Dialight’s 5-year full- performance warranty. Based on performance history, Diamond will likely enjoy up to a decade of reliable illumination, for a truly maintenance-free solution that adds to the significant energy savings. As a result of the energy and maintenance savings, the company easily hit its goal of less than two year pay back.

Employees immediately recognized the difference in the crisp, white, glare-free light at the Ripon facility compared to other plants that do not yet use LED. In fact, the project at Ripon has been such a success, Diamond is considering an LED retrofit at its Lathrop plant just up the road.
