All You Need to Know About DLC Listed LED Grow Lights

If you’re involved in horticulture or indoor farming, you understand the critical role that lighting plays in optimizing plant growth and yields. LED grow lights are the popular options for horticulture lighting. But how do you know which ones truly deliver on efficiency and performance claims?

DLC qualification is one of the trusted standards for assessing the quality and performance of LED grow lights. The DLC (DesignLights Consortium) is a non-profit organization that establishes rigorous performance standards for commercial LED lighting products. DLC qualification and listing provide growers with independent verification that LED grow lights meet stringent requirements for efficiency, quality, and sustainability.

In this blog, we will give you a lasted and comprehensive overview of DLC qualifications and the keys you need to know about DLC listed LED grow lights.

What is DLC qualification?

DLC qualification refers to the LED lighting qualification program administered by the DesignLights Consortium. DLC aims to improve lighting quality and save energy for people and the environment. It is a non-profit program in North America that recognizes and lists high-performing, energy-efficient LED lighting products, including LED grow lights.

The DLC periodically revises its Horticultural Technical Requirements to align with advancements in technology. The latest version (V3.0) focuses on efficacy, structural updates, and administrative improvements.

To earn DLC qualification, LED grow lights meet stringent technical requirements on energy efficiency, performance, reliability, and safety standards. For horticulture lighting manufacturers, obtaining DLC qualification for their LED grow lights demonstrates their commitment to producing high-quality, energy-efficient products.

What are DLC listed LED grow lights?

DLC listed LED grow lights are LED horticulture lighting products that have been verified to meet DesignLights Consortium's stringent technical requirements. These products are listed on the DLC Horticulture Lighting Qualified Products List (Horticultural QPL). To be eligible for listing on the DLC Horticultural Horticultural QPL, LED grow lights must comply with the provisions outlined in the technical requirements document.

The lasted version of Horticultural Technical Requirement is V3.0. It was released in late November 2022 and effective in March 2023. DLC requirements support the adoption of LED luminaired, lamps, and controls in CEA facilities, including cannabis cultivation.

As for 2024, DLC listed LED grow lights have key factors as follows:

• Achieving the minimum photosynthetic photon efficacy (PPE) of 2.30 μmol × J⁻¹.
• Maintaining long-term performance at least 90% after more than 36,000 hours of use.
• Ensuring a minimum driver lifetime of 50,000 hours
• Providing a fixture warranty of no less than 5 years and a lamp warranty of at least 3 years
• Certified by relevant safety certification bodies, like Underwriters Laboratories (UL) with UL 8800 specifically for horticulture lighting products.

Why should you choose DLC listed LED grow lights?

Quality assurance

DLC lighting serves as a mark of quality and reliability. DLC qualification ensures that the LED grow lights have undergone rigorous testing and evaluation, guaranteeing their performance and adherence to industry standards.

Longevity and durability

DLC certified LED grow lights are built to last. They undergo thorough testing to ensure their durability and longevity, reducing the need for frequent replacements and providing cost savings in the long run.

Lower energy consumption

DLC listed lights are significantly more energy-efficient, translating to reduced electricity bills over time. This can be a significant saving, especially considering the continuous operation of grow lights.

Optimized spectrum

DLC listed LED grow lights provide precise wavelengths essential for photosynthesis and overall plant health. You’ll achieve better growth, flowering, and fruiting with the right light spectrum.

What to look for when buying DLC qualified LED grow lights?

When buying DLC qualified LED grow lights, there are several important factors to consider to ensure you select the right lighting solution for your horticulture needs. Here are key aspects to look for:

Verify DLC qualification

Firstly, verify that the LED grow lights are indeed DLC certified. Check that the specific product model number is DLC listed and active in the DLC Horticulture QPL. This can ensure the LED grow lights have undergone the test and evaluation process, meeting the standards for energy efficiency and performance.

Lighting intensity and coverage area

Consider the light intensity and coverage area provided by the LED grow lights. Evaluate the light output and determine if it matches the specific requirements of your horticulture setup. Ensure that the coverage area aligns with the size of your cultivation space for optimal light distribution.

Spectral output

Different plant species and growth stages have specific light spectrum requirements for optimal photosynthesis and growth. Ensure that the spectral distribution of the LED grow lights meets your horticultural needs.

Customization and control features

Check if the LED grow lights offer customization options and control features. Some lights may provide adjustable spectrum settings, dimming capabilities, or programmable timers, allowing you to fine-tune the lighting conditions.

Compatibility and connectivity

Ensure that the LED grow lights are compatible with your horticulture setup and infrastructure. Consider factors such as mounting options, connectivity interfaces, and any additional accessories or components required for installation or integration.
