When choosing an LED driver, it is important to understand the level of safety standard compliance to create the safest possible LED lighting management system. Products are marked with designations for a reason, assuring consumers of product status as safe items, noting components requiring additional safety measures, and registering whether the energy output is safe to human touch. The designations that consumers will want to understand and look for include:

• UL Listed
• UL Recognized Component
• UL Class 1
• UL Class 2

UL Listing and UL Recognized Designations

UL is a global independent safety science company with more than 120 years of expertise innovating safety solutions. The company advises, audits, certifies, educates, inspects, tests, validates and verifies to maintain safety standards and compliance in manufacturing. When UL has tested representative samples of a product and determined that it meets UL’s published, nationally-recognized Standards of Safety requirements, the product is given a UL Listed designation. The designation UL pertains to the United States, and cUL is the Canadian designation.

While a UL listing designates that a product has been tested by UL, meets nationally recognized safety standards, and has been found free from reasonably foreseeable risk of fire, electric shock and related hazards, another similar-looking designation means something slightly different. UL Recognized Component Marks verify that a product has been tested, but that it is a part or component of a larger product. Components can be used to complete or add to end products and systems, but additional installation precautions may be necessary to ensure safe use. It is important to understand how UL Recognized items work to implement the items safely.

Class 1 and Class 2 : Why They Matter

When an LED driver is listed as UL Class 2, it complies with UL standard UL1310 indicating that energy output of the device is safe to touch with no major safety protection required. A UL Class 2 listed item will not carry a risk of fire or electric shock at the LED and luminaire level, operating below 60 volts in dry applications, 30 volts in wet applications, 5 amps, and 100 watts. This safe output restricts the number of LEDs the Class 2 driver can run, but will be safe for use without additional safety measures in place.

UL Class 1 drivers, on the other hand, possess output ranges that exceed UL Class 2 guidelines. Class 1 drivers have high-voltage output which requires safety protection within the LED lighting fixture. Class 1 drivers can run a higher number of LEDs than a Class 2 driver, making it more efficient in terms of energy output, but as such requires putting additional safety measures in place.

The Basics of LED Grow Lighting

All plants have the same needs—including nutrients, air, water, and an optimal temperature setting—but require a different combination of factors to grow most efficiently. Horticultural LEDs support the growing process through augmented light waves designed to enhance photosynthesis. LED grow lighting systems can be as small or as large as a designer desires, depending on the purpose of the system and the lighting components used. These systems are customizable to fit the needs of crops or yield goals through a variety of LED lighting products.

Why use LED grow lights instead of traditional systems? Urban farming systems are constantly exposed to moisture, humidity, and higher-than-average temperatures to increase plant growth. LED drivers are designed to withstand these conditions, and can more precisely tune and deliver appropriate lighting for different crops as needed. The adaptability and reliability of horticultural LED applications make LED grow lights the obvious choice for urban farming situations.

LED lighting applications are always changing. GRE Alpha, a pioneer in LED lighting and powering innovation, is at the forefront of one of the newest uses: horticultural LEDs and LED grow lights for rural and urban agricultural settings. In fact, a new Specialty Solutions section of the GRE Alpha website recently launched, a resource for horticultural and grow lighting customers interested in sourcing power solutions for LED grow lamps.

Modern Farming: Horticultural LEDs and LED Grow Lights

Plants need nutrients, air, water and the right temperature to grow. Horticultural LEDs support the growing process by providing the best recipe of light waves to enhance photosynthesis. Typically featuring traditional lighting elements and used in settings no natural light can reach—or where supplemental lighting might be necessary—grow lights allow for plant and crops to be grown in less-than-optimal conditions. These traditional grow lighting systems are cropping up in apartments and retrofitted warehouses in cities, backyard sheds in suburbia, as well as places with long winter seasons, among other places, to increase agricultural output.

LED grow lighting accomplishesthe same aims as traditional grow lighting systems, butwith less energy output and a better overall yield. Passionate about expanding the applications of its LED products, GRE Alpha is excited to explore the many ways its products can enhance urban farming and agriculture.
