Is lamp light good for plant

In September 2020, the DLC released the official version of the Grow Light V2.0 standard, which will be implemented on 21st, March, 2021. Prior to this, all DLC applications for plant lights will continue to be reviewed according to the V1.2 standard requirements.

The updated content of the official version of the plant lamp V2.0

Keep the requirement of V1.2 version PPE≥1.9μmol/J unchanged
In the first draft of Grow Lamp V2.0, the DLC plans to increase the PPE photosynthetic photon efficiency value to 2.10 μmol/J. However, after collecting feedback on the draft, DLC realized that grow lights are an emerging market. For the sustainable development of the market, DLC decided to keep the PPE photosynthetic photon efficiency value requirements of the current V1.2 standard unchanged, while maintaining -5 % tolerance remains unchanged.

In addition, DLC adds 2 optional reporting parameters, 280-800nm photon flux parameter and efficiency parameter, radiation in this range is usually related to plant growth and development effects.

Revised terminology to comply with ASABE (S640)

The DLC revised some policy terms to better align with American Society of Agricultural and Biological Engineering (ASABE) ANSI/ASABE S640 definitions.

Safety certification requirements meet UL8800

The safety certificate for plant lighting products must be issued by OSHA NRTL or SCC organization and comply with the standard ANSI/UL8800 (ANSI/CAN/UL/ULC 8800).

TM-33-18 data requested

The DLC will require PPID and SQD data information derived according to the TM-33-18 standard.

Family series application

DLC will accept applications for the Family series of grow lights, aiming to reduce testing burden and application fees. The requirements for a product as a Family are as follows:
• The same LEDs must be used;
• Must have the same structure, including electrical, optical and thermal structures;
• Can contain different drivers;
• Different mounting brackets can be included without affecting heat dissipation;
• Must contain the full and detailed model name;
• A model name can only correspond to one brand. When a product is sold under multiple brands, the model name needs to be differentiated accordingly.

Although the current domestic plant lighting is in the ascendant, plant factories have problems such as low input-output ratio and high output products, but many people are still optimistic about the development potential of plant lighting. Then the plant lighting manufacturers need to strictly control the efficiency, color parameters, PPF, PAR, TM-30 and other parameters of the lamps after the production of the lamps. This requires below LISUN Solution:

Option 1: LPCE-2 High Precision Spectroradiometer & Integrating Sphere System.

LPCE-2 Integrating Sphere Spectroradiometer LED Testing System is for single LEDs and LED lighting products light measurement. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters. According to CIE 177, CIE84,  CIE-13.3, IES LM-79-19, Optical-Engineering-49-3-033602, COMMISSION DELEGATED REGULATION (EU) 2019/2015, IESNA LM-63-2 and ANSI-C78.377, it recommends to using an array spectroradiometer with an integrating sphere to test SSL products. The LPCE-2 system is applied with LMS-9000C High Precision CCD Spectroradiometer or LMS-9500C Scientific Grade CCD Spectroradiometer, and A molding integrating sphere with holder base. This sphere is more round and the test result is more accruacy than the traditional integrating sphere.

Measures:
• Colorimetric: Chromaticity coordinates, CCT, Color Ratio, Peak Wavelength, Half Bandwidth, Dominant Wavelength, Color Purity, CRI, CQS, TM-30 (Rf, Rg), Spectrum Test
• Photometric: Luminous Flux, Luminous Efficiency, Radiant Power, EEI, Energy Efficiency Class, Pupil Flux, Pupil Flux Efficiency, Pupil Factor, Cirtopic Flux, Plant Growth Lamp PAR and PPF.
• Electrical: Voltage, Current, Power, Power Factor, Displacement Factor, Harmonic
• LED optical maintenance test: Flux VS time, CCT VS time, CRI VS time, Power VS time, Power Factor VS time, Current VS time and Flux Efficiency VS time.

Option 2: If you have enough budget, you can buy Lishan LSG-1800ACCD/LSG-1890BCCD Goniospectroradiometer

What is Goniospectroradiometer?

LSG-1890BCCD/LSG-1800ACCD Goniospectroradiometer=LSG-1890B/LSG-1800A Goniophotometer System + LPCE-2 Integrating sphere Spectroradiometer System. LSG-1890BCCD/LSG-1800ACCD goniospectroradiometer is high precision automatic goniophotometric instrument for luminous intensity distribution measurement with facility for rotating the light source. The LSG-1890BCCD/LSG-1800ACCD can do the spatial CCT test and the intensity distribution test. It is for industrial laboratory photometric data measurement of luminaires such as LED luminaires, LED Plant Lighting, HID luminaires, fluorescent lamps and so on.

Measurement:
Luminous Intensity Data, Luminous Intensity Distribution, Zonal Luminous Flux, Luminaries Efficiency, Luminance Distribution, Coefficient Of Utilization, Luminance Limitation Curves Glare, Maximum Ratio of Distance to Height, Equal Illuminance Diagrams, Curves of Luminaires VS Lighting Area, Isocandela Diagrams, Efficient Luminescence Angle, EEI, UGR, CCT, CRI, Color Temperature Distribution, Spectrum, (x, y)/(u, v), PAR, PPF, PPFD 3D distribution test and etc.
