Optimized Full Spectrum (3000K / 5000K / 660nm / 730nm):Engineered with a scientifically balanced spectrum combining white (3000K + 5000K), blue, deep red (660nm), and far-red (730nm) to support photosynthesis efficiency across all growth stages. Designed to improve light utilization from seedling to harvest, accelerating flowering response and increasing overall yield potential.
High-Intensity Output & Uniform PPFD Distribution:Delivers high photon density output with optimized PPFD distribution across the entire canopy area. Precision diode placement reduces edge drop-off and ensures consistent light intensity from center to perimeter, improving plant uniformity and maximizing productive growth zones for higher yield consistency.
Smart Control & Precision Dimming (25%–100%):Compatible with VIVOSUN GrowHub (sold separately) and mobile app control, enabling automated lighting schedules and remote monitoring. Integrated 4-level dimming system (25%–100%) allows precise light adjustment to match different plant growth stages and environmental needs.
Efficient Thermal Management & Low Heat Stress:Advanced heat dissipation system reduces excess thermal load compared to traditional lighting systems, helping maintain stable canopy temperature and reducing plant heat stress. Supports continuous high-intensity operation while protecting internal components for long-term reliability.
Long Lifespan Stability (Q90 / 36,000 Hours):Built with high-quality LED components rated for up to 36,000 hours (Q90 flux maintenance), ensuring long-term photon stability and consistent light output throughout extended cultivation cycles, reducing replacement frequency and operational downtime.
IP65 Waterproof & Dustproof Design:Engineered for demanding growing environments, including high humidity and high-temperature conditions. IP65 protection allows safe operation during watering, nutrient spraying, and cleaning, ensuring durability and stable performance in commercial cultivation setups.
