SZHLUX 400W Full Spectrum LED Grow Light with TimerTemp Control
Category: SF4000

High Efficiency and Low Energy Consumption
SZHLUX LED Grow Lights are powered by the latest high-yielding LEDs technology, delivering a remarkable 2.9 μmol/J energy efficiency. This advanced technology ensures powerful light output with uniform canopy penetration, resulting in maximum higher yields. With an actual power input of 600W and 1,728 LEDs, the effective footprint spans 4 x 6 ft, providing optimal coverage and efficiency.
Temp Control and Timer Modes
The UP2 series boasts an enhanced PT design with a temperature sensor, temperature button, and timer button, allowing precise adjustment of the light hanging height. This feature ensures optimal PPF (Photosynthetic Photon Flux) values, preventing energy waste. The auto-set temperature is 85°F, with specific light bar adjustments: - 86°F: 7 light bars on - 91°F: 5 light bars on - 96°F: all lights off
Sunlight Full Spectrum
Our grow lights mimic the full spectrum of sunlight, with over 95% light energy absorbed by plants. The spectrum includes: - 3000K (white with reddish tint) - 5000K (blueish white) - 660nm (red light) - 730nm (infrared light)
The 5000K spectrum accelerates seedling growth, while 660nm and 730nm promote photosynthesis, enhance flowering and fruiting, and increase yield and crop quality.
Trapezoid Tube and Fanless Design
Unique in design, the Trapezoid-shape LED tube offers a larger luminous area compared to T5 and T8 tubes. An innovative premium aluminum shell without a fan ensures faster heat dissipation, providing a quiet and easy-growing environment for your plants, ensuring they receive the maximum energy without overheating.
Cost-Effective Upgraded Grow Lamp
Compared to HPS lights, larger light fixtures cost about half in terms of energy savings. The UP2 series is equipped with the latest drive technology, featuring temperature controls and timing design buttons instead of traditional dimming knobs. This modern design is scientifically optimized for every stage of plant growth, ensuring optimal performance and cost-effectiveness.
