20W LED Grow Light Strips Technical Specifications
Optical and Radiometric Parameters
| Parameter Name(Specification) | Engineering Parameters /Standards | Technical Note |
| Total radiated power(system PPF) | 52 – 56 µmol/s | Designed for the interior space of the tree canopy, it provides a gentle yet efficient flow of photons to activate photosynthesis at the base layer. |
| System Lighting Effects(system PPE) | 2.6 – 2.8 µmol/J | High-efficiency output ensures strict control over the overall energy consumption cost of commercial facilities when providing supplemental lighting for the sides and bottom. |
| Center limiting intensity (max PPFD) | > 80 µmol/m²/s | Measured 6 inches (15 cm) from the leaf. Designed for safe light intensity to prevent light burn to the lower leaves from close-range exposure. |
| Core footprint | 4 × 0.5 ft (1.2m × 0.15m) | The standard linear light-emitting area perfectly matches the gaps between plant rows and is specially designed for three-dimensional supplemental lighting of the middle and lower parts of the plant. |
| LED chip matrix(diode array) | Samsung + Osram | It uses diodes from leading global manufacturers, which have extremely high resistance to decay and tolerance to cope with the high humidity microclimate environment inside the tree canopy. |
| Spectrum configuration | Sub-canopy optimized canopy penetration spectroscopy | The underlying environment is optimized by increasing the red-blue ratio, which aims to delay the aging of older leaves at the bottom and stimulate the volume and density of hidden flower buds. |
Electrical Parameters
| Parameter Name(Specification) | Engineering Parameters /Standards | Technical Note |
| System actual power consumption (AC input power) | 20w±5% | Extremely low power consumption is accompanied by extremely low heat dissipation, allowing the light strip to operate close to the plant canopy without affecting the microenvironment temperature. |
| Input voltage | 120-277V AC | Wide voltage drive, perfectly covering mainstream power distribution systems in North American commercial greenhouses and indoor vertical farms. |
| Power factor | > 0.95 | Efficient electrical design reduces line loss and ensures electrical safety in large-scale projects with multiple wiring harnesses operating under high loads. |
| Total Harmonic Distortion (THD) | < 15% | It meets advanced industrial access standards and causes no interference to the power grid. |
| Dimming protocol | Plug and play / Daisy chain | The canopy underlighting typically operates at full power. It features built-in waterproof male and female connectors, supporting plug-and-play and seamless daisy-chaining. |
| Maximum number of daisy chains | 50 – 100 wires (depending on input voltage) | It greatly simplifies commercial cabling costs and labor, as a single main power cord can power the entire row of plants’ bottom light strip system. |
Structure and Thermal Management
| Parameter Name(Specification) | Engineering Parameters /Standards | Technical Note |
| Thermal management | Passive cooling | With an extremely low heat output of 20W, it features an extruded casing made of 6063 aerospace-grade aluminum. Its completely silent, fanless design relies on natural convection heat dissipation through surface area, without altering the local temperature field at the base of the canopy. |
| Ingress protection level | <IP66 / IP67 | Key indicators: Subsurface lighting is highly susceptible to damage from irrigation system spraying, dripping, and high humidity. Both the light strip itself and its connecting wires must meet standards for complete dustproofing and resistance to strong water jets/brief immersion. |
| Lighting fixture dimensions | Approximately 47.2″ × 1.5″ × 1″ (1200mm × 38mm × 25mm) | The ultra-thin T5/T8 tubular or flat shape can be perfectly embedded in the spacing between plant rows, minimizing obstruction to air circulation and ventilation in the greenhouse. |
| Net weight | < 2.2 lbs (< 1.0 kg) | The ultra-lightweight design reduces the load on the support structure, enabling rapid large-scale deployment by a single person in commercial facilities. |
| Installation methods (mounting options) | Suspended / Bracket clips / Nylon straps (suspended / clips / zip-ties) | It offers highly flexible installation kits that can be directly tied to the bottom of plant support frames, posts, or planting beds to adapt to complex underlying space structures. |
| Beam angle | 120° (wide beam angle) | Without the need for a lens to focus the light, the wide-angle beam allows the light to be distributed as evenly as possible across the surrounding stems and leaves within a limited, close distance. |
Business and Engineering Compliance
| Parameter Name(Specification) | Engineering Parameters /Standards | Technical Note |
| Safety certification | UL8800 / ETL / CE / RoHS | It must meet the highest electrical safety standards for garden lighting facilities in North America and Europe to ensure that there is no risk of leakage or fire in long-term high humidity environments. |
| Energy efficiency certification (efficiency rebate) | DLC horticultural Listed (QPL) | This meets the stringent eligibility criteria for North American commercial farms to apply for substantial energy-saving rebates from local power companies (such as PG&E, Edison, etc.). |
| Luminous flux maintenance (lifespan/lumen maintenance) | L90 > 50,000 hours | It has an extremely wide operating window for temperature and humidity, making it fully adaptable to the high-temperature and high-humidity operating environment of enclosed greenhouses and indoor vertical farms. |
| Operating environment tolerance | Temperature: -10°C to 40°C Humidity: 20% – 95% RH | The outer sheath of the wire must withstand ultraviolet aging and corrosion from fertilizers, acids, and alkalis, and must meet fire-retardant standards. |
| Corrosion resistance of the casing | Anodizing / UV-resistant coating | Surface treatment must be able to resist corrosion and aging caused by fertilizer and nutrient solution splashes, as well as long-term ultraviolet radiation, to extend the structural life. |
| Warranty period | 5-year manufacturer warranty | The industry-leading B2B engineering commitment significantly reduces the post-construction maintenance and replacement costs for large farm owners. |
