LED Grow Light Board
Product Overview
| The EG-QBLG series LED quantum board grow light is a professional-grade horticultural lighting solution engineered for commercial greenhouses, vertical farming operations, multi-tier propagation racks, and controlled environment agriculture (CEA). Built with premium SANAN 2835 and 3030 LED chips mounted on a monolithic aluminum circuit board, this quantum board delivers industry-leading photosynthetic photon efficacy (PPE) of up to 2.7 µmol/J and highly uniform PPFD distribution across the entire growing canopy. Unlike COB grow lights that create concentrated hotspots and high-pressure sodium (HPS) fixtures that waste over 60% of energy as heat, our quantum board design spreads diodes evenly across the panel for balanced, deep-penetrating light with minimal thermal load. Rated IP65 for dust and water jet resistance, it operates reliably in humid greenhouse environments, propagation zones with daily misting, and outdoor covered growing areas. Available in 5 power ratings from 65W to 600W, the series supports 0-10V analog dimming and daisy-chain connectivity, making it fully scalable from small propagation rooms to large-scale commercial farms. The optimized full-spectrum output supports every growth stage from seed germination and vegetative growth to flowering and fruiting, delivering higher yields, better crop quality, and faster growth cycles compared to traditional lighting technologies. |

Optimized Full Spectrum for Targeted Crop Performance
| The EG-QBLG series features a scientifically calibrated full-spectrum indoor light recipe designed to maximize photosynthetic efficiency and crop quality. The base spectrum combines 450nm deep blue and 660nm deep red wavelengths - the two most photosynthetically active regions of the PAR range - with optional 385nm UV-A and 730nm far-red enhancements for targeted physiological responses. Wavelength Breakdown & Horticultural Benefits - 450nm Deep Blue: Drives chlorophyll A/B production and regulates stomatal opening for strong vegetative growth. Enhances leaf development, stem strength, and compact plant architecture. Critical for seedling propagation and leafy green production. - 660nm Deep Red: The most photosynthetically efficient wavelength, driving peak photosynthesis rates. Promotes robust flowering, fruit set, and carbohydrate accumulation. Directly impacts yield, fruit weight, and sugar content in fruiting crops. - 385nm UV-A (Optional): Stimulates secondary metabolite production, enhancing anthocyanin levels, terpene production, and natural pest resistance. Improves color intensity, flavor, and nutritional value in high-value specialty crops. - 730nm Far-Red (Optional): Regulates phytochrome response to control photoperiod perception and plant architecture. Extends effective day length, promotes stem elongation, and can accelerate flowering in long-day plant varieties. Custom Spectrum Tuning For commercial growers with specialized crop requirements, we offer custom spectrum tuning services. Adjust red-to-blue ratios, add UV or far-red wavelengths, or match proven light recipes to specific crop varieties including leafy greens, berries, medicinal plants, and ornamental flowers. MOQ applies for custom spectrum configurations. |
Core Features & Commercial Operator Benefits
| IP65 Waterproof & Dustproof Construction Fully sealed aluminum panel design delivers IP65 protection against dust ingress and water jets from any direction. Unlike open-face LED boards that fail prematurely in humid, dusty growing environments, the EG-QBLG series withstands daily overhead irrigation, misting systems, and regular facility washdowns without risk of electrical damage or corrosion. This rating makes it suitable for both indoor grow rooms and covered greenhouse applications. High-Efficiency 0-10V Dimming Control Compatible with all standard 0-10V analog lighting controllers, allowing smooth, flicker-free brightness adjustment from 10% to 100%. Dimming enables growers to match light intensity to growth stage, acclimate young plants, and reduce energy consumption during low-demand periods. The system supports group dimming for zone-based light management in large facilities. Passive Aluminum Thermal Management The entire aluminum circuit board functions as a large-format heatsink, absorbing and dissipating heat evenly across the panel surface without fans or moving parts. This passive cooling design: - Eliminates fan failure points in high-humidity, high-dust environments - Operates completely silently - ideal for research facilities and enclosed grow spaces - Maintains stable LED junction temperatures for maximum lifespan and consistent light output - Reduces HVAC cooling loads compared to HPS and fan-cooled LED fixtures Superior Electrical Performance - High Power Factor: >0.90 for 65W model, >0.95 for 100–600W models, minimizing reactive power waste and reducing utility demand charges - Flicker-Free Output: 100% flicker-free operation compliant with horticultural lighting standards, preventing plant stress and inconsistent growth patterns - Wide Voltage Input: AC 100–277V 50/60Hz universal input, compatible with global electrical grids for international projects - Low Total Harmonic Distortion: Clean power that does not interfere with other facility control equipment Scalable Daisy-Chain Connectivity Panels support parallel daisy-chain wiring for simplified installation in large-scale projects. Multiple fixtures can be linked on a single circuit and controlled collectively, reducing wiring labor and material costs. |
