ZIGEN Featured in LED Professional Review
It was not long ago that the ability to have control over the CCT (correlated color temperature) of your light source was inconceivable. Now, thanks to ZIGEN Lighting Solutions supported by GRE Alpha’s tunable white dimming module, the industry’s first tunable white COB LED product series has been introduced. Labeled ZG7, the On-BBL tunable white COB LED changes luminous colors following the blackbody locus (BBL) by just using a 2-channel input.
While conventional tunable white LED only starts from 2700K or above and can result in a pinkish color at mid-range, ZIGEN’s newly patented technology using 3 phospor color ranges from 2000K sunset color temperature to 5000K which eliminates the unwanted pink and expands the adjustable color range to human centric lighting applications. It is a major step forward in tunable white lighting that is being welcomed by architects, engineers and building managers alike.
Consider ZIGEN’s ZG7 tunable white series solutions to help maximize ambiance and well being for:
Listed above is a mere sliver of the usage possibilities in ZIGEN’s new tunable white technology. According to ZIGEN management, they are planning to adopt this new technology to higher power COB and SMT solutions in the near future. GRE Alpha is proud to be an LED powering partner with ZIGEN and looking forward to supporting their progress in any way possible. About ZIGEN Lighting Solution Co., Ltd

Your investment in lighting faces two types of very real electrical threats to the equipment itself and to the operator and the public safety.
(Source: LEDs Magazine)
The first threat is a momentary voltage or current spike that can damage or destroy your equipment. These can occur in both indoor and outdoor installations.
The second hazard, primarily if your lighting is outdoors, is the perpetual threat of lightning strikes. The long copper cables that carry power or data signals from LED power supplies or controllers can unintentionally mimic lightning rods, drawing in danger from the very sky itself.
Having appropriate protection in place to handle common power quality issues, such as over voltage's is important
The GRE Alpha SEL-20kA Surge Energy Protector is a surge limiter that provides maximum protection for your lighting investments. The UL Listed Class 2 device complies with UL1449, EN 60.364-5-534 and EN 62.305-1. The SEL-20kA provides effective surge protection against surge over voltages, providing effective coverage against both direct and indirect lightning strikes.

This device is a UL Type 2 surge protection device (SPD), which means that it is designed to protect against 8/20 µs current waves. It provides protection against pulses of up to 20kA / 20kV and is designed to operate from AC line voltages ranging from 100 to 277, with a 320 VAC continuous maximum.
This surge protector protects against line to line and line to ground surges and includes a LED device status indicator.
The GRE Alpha SEL-20k Surge Energy Protector comes fully potted, which means that all unoccupied space with the device is filled with a solid or gelatinous compound. This makes it impossible for water to get in to cause short circuits or other damage. Additionally, during stormy weather, the air itself can be charged with electricity, and can cause electrical sparking. Potting fills all the empty space and eliminate either of these potentially disastrous outcomes.

The unit enjoys an IP65 rating from the International Electrotechnical Commission (IEC). This means it is 100% protected against dust and is also protected against low pressure jets of water from all directions.
The GRE Alpha SEL-20kA Surge Energy Protector is a UL Listed Class 2 device that also complies with the UL 1449, CSA C22.2 NO. 269.4-14, CSA C22.2 NO. 269.5-15 and CE safety standards.
It operates over a temperature range of -40°C to +70°C, and over relative humidity of 5% to 95%. Unit size is 70mm (L) x 60mm (W) x 50mm (H). Read more

Ultra High Resolution and Digital Filtering Enhances Dimming for Smooth Dim to Dark
GRE Alpha, an emerging leader in the design and manufacture of solid-state lighting power supplies, is excited to announce the release of their newest smart dimming module.
The SLD-DIM1X module is an enhanced version of GRE's innovative SLD-DIM1B dimmer, featuring ultra-high resolution dimming. With 10,000 dimming steps (versus 1024 in the SLD-DIM1B) and GRE Alpha's advanced digital filtering technology, the SLD-DIM1X dimming module provides best-in-class, flicker-free (PWM) pulse width modulated dimming for 0-10V dimming applications. These enhancements make the dimming process smoother, especially at the low end- dim to dark. For cost sensitive projects with moderate dimming performance requirements, GRE Alpha's original model SLD-DIM1B remains the wise option.
These easy-to-install dimming modules work with commercial 0-10V dimmer controls (1V=0% brightness, 10V=100% brightness), and connect between any Class 2, AC-DC LED driver and LED Fixture/Luminaire to enable exceptional, flicker-free dimming. The SLD-DIM1X can be installed into any of GRE Alpha's SLD/XLD series LED driver's DC wiring cavity, eliminating the need for external junction boxes, resulting in a quick, low cost installation.
GRE Alpha's executive director, Richard Fong, had this to say: 'I am proud to announce that GRE Alpha's talented design team is continuing work on a series of innovative, high-quality LED drivers and modules that will take our popular line of LED powering products to the next level. The exceptional performance of the SLD-DIM1X is a prime example, with its enhanced, superior dimming. The architectural lighting industry- especially lighting OEM companies that continually strive to provide higher quality dimming performance in their LED fixtures- have been among the first to adopt our newly enhanced dimming products.'
It is important to note that the SLD-DIM1X is a new addition to GRE Alpha's growing line of high-quality LED dimming modules and drivers. The SLD-DIM1B as well as the rest of GRE's high-efficiency, high reliability SLD series products will continue to be offered and supported. The following chart illustrates the functional comparison between our new SLD-DIM1X and our original SLD-DIM1B dimming modules:
