Sayhon Sh4000 Dimmable Led Grow Light, Full Spectrum With Uv/Ir For Indoor Plants & Greenhouses

SUPPLEMENT BAR
SAYHON’s innovative built-in supplement bar features a convenient switch, delivering the perfect blend of Blue, Red, and IR light for optimal photon emissions across the entire photosynthetic spectrum. This addition is designed to enhance plant growth throughout its entire cycle, allowing you to easily turn the supplement bar ON/OFF independently with the built-in switch.
OPTIMIZED FULL SPECTRUM & HIGH EFFICIENCY
Equipped with the latest diodes and SAYHON’s ADVANCED FULL SPECTRUM technology (390nm~760nm), this grow light provides perfect spectral output at every growth phase. With a high energy efficiency rating of 2.7 umol/J, it ensures optimal photon energy concentration and yields, achieving 200% greater canopy penetration and a 30% increase in yield.
CUSTOMIZED DIMMING DESIGN
The adjustable dimming feature, ranging from 5% to 100%, allows you to tailor the LED grow light's intensity, effectively minimizing wasted energy. This ensures your plants receive their ideal spectral ratios from seed to harvest, promoting healthier growth and maximum yield.
UPDATED HEAT DISSIPATION & LONG LASTING
A heavy-duty aluminum heat sink provides over 200% heat dissipation area, resulting in temperatures that are more than 30% lower compared to other brands. This design prevents overheating, ensuring that light output remains consistent over time without the need for fans.
RELIABLE QUALITY & NOISE FREE
Featuring a UL Listed Waterproof Driver and a Glue Cover Process, this product guarantees the highest quality and safety standards. It is designed for effortless Plug and Play installation without noise, making it an ideal choice for both home and commercial growing environments.
