HONG KONG - GRE Alpha Electronics, Ltd., a designer and manufacturer of LED power supplies and systems, has added Arrow Electronics as an official distributor of their products. This marks GRE Alpha's fifth distribution outlet.
Founded in 2009 GRE Alpha focuses on an LED niche often neglected - modular design. Unlike many LED driver and accessory manufacturers, GRE Alpha creates products that can be integrated into existing setups. This allows their products to be swapped out for newer models as they release, or to be replaced if damage occurs.
"GRE Alpha's aim is to provide reliable, easy-to-install LED power solution to the LED lighting market," says Richard Fong, GRE Alpha's Executive Director. "With a flexible power platform, GRE Alpha's unique modular systems allows users to upgrade their existing lighting systems with various dimming options when needed without the hassle purchasing another LED driver, saving both costs and reducing SKUs."
GRE Alpha doesn't just create LED components; they often provide help and information to those in need. For example, they recently addressed the dangers of power surges - something that can cause tremendous amounts of damage to LED lighting, drivers, and modules for businesses. They state their SEL-20kA Surge Energy Protector can help mitigate the damage from power surges. This product and more will be on display at Hong Kong's International Lighting Fair from Oct. 27-30, during which time GRE Alpha hopes to give attendees a firsthand look at the benefits of a modular approach.
The Colorado-based Arrow Electronics has a global reach, with access to distribution in 29 countries. Since their founding in 1935, Arrow has focused on providing access to cutting-edge technology around the world.
“Our partnership with Arrow will greatly enhance our product reach and will allow us to reduce our lead times and provide better on-time service to our clients worldwide,” Fong says.
While based in Hong Kong, GRE Alpha aims to make their modular solutions available worldwide. With Arrow's 2016 sales coming in at $23.8 billion, GRE Alpha's goal of furthering their product reach looks to soon be a reality.

LED lighting investments can cost thousands of dollars – ignoring the possibility of unchecked power line transient voltage surge can be devastating. GRE Alpha’s surge protection device acts as a flood wall that guards against transient voltage surges, enabling the lighting system to stay intact, and saves the costs associated with replacement.
The risk of surge-related damage is even greater today, due to LEDs being more complex than in the past. Dimming and other functionality have resulted in more parts and circuits that can be damaged or destroyed by a lightning or power surge.
So, how can you protect your investment, while still utilizing state-of-the-art lighting technology?
The GRE Alpha SEL-20kA Surge Energy Protector provides maximum protection by providing effective coverage against both direct and indirect lightning strikes. The SEL-20kA Transient Surge Energy Protector is potted, making it an ideal fit for indoor or outdoor use—this means surge protection that is ideal for various applications, including street lighting and signage. Complying with UL1449 Type 2 SPD, this cUL/UL Listed device provides 20kA max and Voc 20kV, L-L and L-G protection, offering comprehensive protection on various transient and direct surges.
The GRE Surge protector is the ideal accessory for multiple uses and works well with other components. Using GRE’s own patented driver housing as an example, Richard Fong, Director at GRE Alpha states “Our housing design not only saves on installation costs but simplifies wiring and allows for the addition of accessories such as surge protection and our dimming modules for tuning lighting recipes.”
Unlike many products, GRE Alpha’s lighting solutions keep the LED power supply, dimming functionality, and protection circuitry separate. This lets you decide which functionality is most important to you. For example, the SLD SMART-DIM MODULE can be added onto existing lights, making them dimmable when you’re ready.
Wiring can be done within the product's wiring compartments without the need for external junction boxes to house the wiring and the LED driver. GRE Alpha’s patented driver has integral wiring compartments as part of the core design. As a result, the Smart Dim Module:
The modular approach offers numerous advantages. Other solutions in the market already incorporate all functions in one product, which leads to feature creep and forces the customer to buy features that they don't necessarily need. According to Mr. Fong, “Our approach allows us to separate the module and to make sure our products do each thing well without compromising on cost or performance.”
Attendees of October’s Hong Kong International Lighting Fair will be able to see these products at Booth No. 1CON-003, ED-TSO and make the comparison themselves.

If you have attended a trade show recently, the buzz surrounding LEDs and the incorporation into luminaire design is inescapable. Previous generations of LED luminaires attempted to incorporate LEDs into essentially the same design as their traditional counter parts. This limited both performance and possibilities. As the demand for energy efficient lighting increases integrating LEDs into design becomes less of an afterthought. LED luminaire design is very different from traditional fixture development. LED luminaire design requires a systematical approach that balances competing requirements such as:
LED lighting is known for its efficiency but even the most efficient light sources would be judged inadequate without high-quality optics. A compact fluorescent lamp, for example, can lose up to 70 percent of its light if paired with an inappropriate optic, says Nadarajah Narendran, director of research at the Lighting Research Center (LRC), in Troy, N.Y. Likewise, the touted efficacy of LEDs wouldn’t exist without the right optics. (archlighting.com) As efficiency and thermal performance in LED packages continue to improve, they pose design advantages. Fewer LEDs may be needed to satisfy light levels and optical distributions. This allows even greater flexibility in optical and mechanical design. This empowers lighting manufacturers to create lighting solutions tailored to meet the most demanding field requirements and yield maximum supply chain value.
While luminaire designers are making tremendous leaps using technology, there are some practical considerations to keep in mind. Supplying power to these innovative light sources requires specialized LED drivers. LEDs are designed to run on low voltage (12-24V), direct current electricity. Conversely, the most common power supply is at a higher voltage (120-277V) using alternating current electricity. An LED driver rectifies this problem. Secondly, protection from voltage or current fluctuations come into play.
Too much or too little current can cause light output to vary or degrade faster due to higher temperatures within the LED.
Heat dissipation is and has been one of the primary challenges with LED technology. LED junction temperature must be kept below manufacturer specified levels to achieve long life. Luminaires with smaller form factors tend to have poorer thermal performance. This can lead to compromises such as a lowering the intensity of the light or sacrificing some longevity in favor of intensity.
Updated energy codes require efficient, bilevel lighting. This tips the scale toward units that low in power and often offered with 0-10V dimming control standards. Greater energy savings are achieved through occupancy and daylight dimming controls. As digital light sources, LED lighting fixtures can be precisely controlled with dimmers, push-button devices, wireless touchscreens, smart phones or integrated into a structure’s IT system. Digital Multiplex (DMX) and Digital Addressable Lighting Interface (DALI) protocols have become widely adopted. While the initial priority focused on making commercial lighting more controllable, popularity has increased and it is now used in various applications, including hotel, restaurant, and residential settings.
GRE Alpha has a wide array of products that elevate luminaire design.
The GRE Alpha XLD 75 and XLD 200 both offer dual modes, giving you constant current and constant voltage options. Furthermore, both the output current and voltage are adjustable, letting you get the most optimal performance from your light fixtures. And as the only UL listed LED drivers on the market, you can use them to drastically reduce your approval times and agency approval costs.
Both of these models are easy to install thanks to our patented enclosures, which simplify wiring requirements. Fast to install and capable of working in temperatures ranging from - 40°C to -60°C, both options will have users remotely controlling their lighting in no time, no matter the environment.
The DALI Dimming Module and SLD-DIMTW Tunable White Dimming Module give users even more advanced customization and control of their lighting. Both capable of being incorporated into your existing LED drivers, these solutions offer customization with an extremely small form factor, high efficiency, and competitive cost. Easy to install and inexpensive, this simple upgrade can be implemented on new lighting projects, or retrofit to your older fixtures, enabling them to support industry standards like 0-10V, DALI, DMX, TRIAC, wireless and more.
