Dialight’s Newly-Launched All-LED High Intensity L-856 Strobe Earns a Pick Hit Award from Radio Magazine at NAB

Vigilant™ Series LED High Intensity Strobe Becomes Fourth Dialight Product to Earn Industry Distinction

Las Vegas - 2011 NAB Show (April 19, 2011) - Dialight (LSE: DIA.L), an innovative global leader in LED lighting technology, today announced that its Vigilant™ Series All-LED L-856 High Intensity Strobe has been recognized by Radio magazine, the Radio Technology Leader published by NewBay Media, with a Pick Hit Award during the 2011 NAB Show. The Radio magazine Pick Hits panel selects the top 15 new products introduced at the convention. The 2011 distinction marks the fourth time a Dialight product has earned the coveted award.

"The Pick Hit Awards are limited to 15 winners, which maintains the value and prestige of the award," said Chriss Scherer, editor of Radio magazine. “In addition, the Pick Hit Award judges follow a strict set of rules and make their selections independently and anonymously, which is a further testimony to the proven value of the award to radio broadcasters."

Designed for obstruction lighting on communication and broadcast towers, smoke stacks and other obstructions over 500 feet, the Vigilant Series L-856 delivers reliable, maintenance free performance for at least five full years—more than double the standard life of conventional Xenon systems. This continuous, worry-free operation eliminates the costly and hazardous annual tower climbs required for frequent change out of Xenon tubes.

In addition to long life and maintenance savings, the new Vigilant Series L-856 High-Intensity Strobe is also offers an energy efficiency advantage over conventional technology, operating at just 250W in day mode (270,000 candela), under 30W in twilight mode (20,000 candela) and under 10W in night mode (2,000 candela). The lower energy load reduces the level of EMI/RFI compared to Xenon systems to minimize communication signals interruption. The system features Dialight’s patented community-friendly optics design to minimize light ground scatter, with a number of other patents filed. The Vigilant Series L-856 High-Intensity Strobe system may be used in up to six levels for a maximum of 18 synchronized flash heads on a single structure.

The product was unveiled for the first time at the NAB event, and is the latest in Dialight’s first-to-market, leading-edge obstruction lighting technologies, with FAA certification pending. The company previously earned Pick Hit awards for its other innovative LED obstruction products in 2001, 2002 and 2007.

“This year’s recognition once again affirms Dialight’s position as the industry leader in LED obstruction lighting products designed to meet our broadcast customers’ unique needs for long life and efficient operation with minimal interference,” said Roy Burton, Dialight’s Group Chief Executive. “We’re very proud to have once again earned the confidence of the Radio magazine Pick Hit judges for our proven technology.”

The Pick Hit Awards were first presented at the NAB Convention in 1985, making them the oldest technology award at the convention. The Pick Hit Awards are selected by a panel of judges who are radio broadcast engineers from radio stations, radio networks and radio production facilities. The Radio magazine staff has no influence in the Pick Hit Awards decision, which ensures that there is no bias in the selections. The official Pick Hit rules require that the winning products must fit a recognized need in radio, are priced within reason, are available within the current calendar year and have never before been exhibited at the NAB Convention.

The complete list of recipients will be published in the June 2011 issue of Radio magazine, and it is available online at RadioMagOnline.com.

Century Aluminum Saves Thousands on Annual Maintenance and Energy Costs with Upgrade to Dialight Vigilant™ Series LED Obstruction Lights

With an operating capacity of 244,000 tonnes per year, Century Aluminum’s Hawesville, KY primary aluminum smelter has been in operation since 1969. The original 400-foot chimney stack featured an incandescent beacon lighting system installed in the 1970s. Looking to upgrade its antiquated technology, the company replaced its vintage beacons with a new, high-efficiency Dialight Vigilant Series L-864 LED red beacon system to gain incredible savings in energy consumption and cost and dramatically cut maintenance expenses.

Antiquated System Saps Maintenance, Operating Budget

The 42-year-old Century Aluminum chimney stack had become a drain on the company’s energy and financial resources. With two sets of four 1400W incandescent beacons and two sets of four 116W sidelights (total of 16 units) operating night and day, the company was spending about $6,000 annually just to keep the lights on. In addition to the operational costs, maintenance was becoming a burden, requiring a minimum of two bulb replacements per year for each of the dozen beacons to safeguard against failure.

With the cost to mobilize a tower-climb team at about $1,800 for each outing, plus at least $80 for each bulb, maintenance costs racked up to nearly $4,000 a year— valuable capital that could be put to better use in the company. In the event of a bulb failure, NOTEM filings and FAA fines could easily push the cost liability into the tens of thousands of dollars.

Dialight Delivers Fast ROI

At the recommendation of Jason Jennett, obstruction lighting engineer with Fuellgraf Chimney & Tower, a leading tower and stack lighting specialist, Century chose Dialight’s ultra-high efficiency, low-maintenance and low-profile Vigilant Series LED beacon system to upgrade its tower lighting. “We calculated an ROI for them that showed these units would pay for themselves in less than 1 year and even a ROI of just over 4 years based on a complete new lighting system including new conduit, cabling and all necessary installation.”

Fuellgraf installed a complete new system consisting of four red L-864 20W LED Dialight beacons on both the top and mid-levels and four steady-burning L-810 red RTO 6.5W LED marker lights between the top and mid-levels and on the bottom. New conduit, cable supports and junction boxes completed the upgrade. The fact that the new units weigh just 20 pounds—one-fourth the size of the incandescents—and the ability to jump straight into the terminal block off the LED beacon without the added terminal block required for traditional beacons, made for easier installation. And, the lower profile design reduces wind load on the units and the tower.

Direct Bottom-Line Savings

The new beacons reduce operating expenses because they consume less than 10% of the power required for the incandescent units, providing a direct positive impact on the company’s bottom line.

“Dialight’s proven products offer the lowest wattage on the market, giving my customers more bang for their buck, plus you get the ‘green’ advantage of reduced consumption all in one package,” Jennett said. “Century is now realizing a CO2 emission reduction of 38 metric tones annually, or the equivalent of removing 7 cars off of the road per year.”

Dialight Launches LED Fixture Specifically Designed for Low-Bay Applications

DuroSite™ LED Low Bay Provides Maintenance-Free Reliability and Durability with Low-Glare Optics for Parking Decks, Cold Storage, Fueling Canopies and Other Low-Clearance Applications

Farmingdale, NJ (April 5th, 2011) – Dialight (LSE: DIA.L), an innovative global leader in LED lighting technology, today announced the launch of its new DuroSite™ LED Low Bay Fixture, the company’s first LED luminaire designed specifically to provide maintenance-free, high-quality light with minimal glare for superb visibility in parking decks, garages, cold storage and other applications under 25-foot mounting height.

Featuring Dialight’s exclusive optics design for precise light distribution and reduced glare, the DuroSite LED Low Bay fixture provides an ideal combination of low-profile durability, long-life performance and maximum energy savings compared to traditional high pressure sodium and metal halide fixtures.

Delivering up to 75 lumens per watt at just 80 watts total power consumption, the DuroSite LED Low Bay ensures at least 50 percent energy savings over HID sources. Available in both cool white and neutral white versions for improved visibility, the Dialight LED Low Bay emits very little heat for minimal impact on cooling systems for added energy savings.

The unit is also available with either a variable dimmer or motion detector/occupancy sensor for further energy savings. Instant-on capability improves safety with immediate full illumination of the area and eliminates the energy often wasted by leaving conventional lights on continuously to avoid the warm-up period.

“Our new Low Bay is a perfect example of Dialight’s understanding of the unique needs of our customers,” said Roy Burton, Dialight’s Group Chief Executive. “This unit can not only help reduce energy consumption and CO2 emissions, but it is extremely durable, featuring an all-aluminum housing with scratch-resistant polycarbonate lens—the same material used in bullet-proof glass. It’s built especially to withstand the risk of vandalism and damage that sometimes happens in parking garages and other low-clearance environments.”

Changeout from existing fixtures is simple, using the same 100-277VAC wiring and mounting structure. The DuroSite Low Bay is compatible with Dialight’s entire line of existing high bay mounting options and accessories including pendant mount, swivel bracket and cable gland (in combination or individually), hanger loop and hook, stanchion bracket, junction box with integrated transformer, and dome lens

The unit is UL1598/UL1598A rated and CSA22.2 #250 certified and is backed by Dialight’s standard 5-year Peace of Mind Warranty, guaranteeing at least five years of reliable, maintenance free performance.
