Integrated Circulation Fan: The centrally located circulation fan in the LED balances airflow where other fans cannot reach, allowing more air to enter the canopy directly; Must be used with VIVOSUN Growhub Controller E42/E42A/E25 to achieve many functions Full-spectrum Sunlike Lighting: These LEDs deliver optimal light-spectrum coverage (380nm-780nm, 660nm, 3000K, 5000K) and produce maximum PAR output at various distances; The lights can get through the surface of plants and deep into them to increase yields Smart Control and Programming: The AeroLight SE is compatible with the VIVOSUN GrowHub Controller and App; You can also automate and customize day/night schedules to simulate natural environments; This package does not include this controller, which needs to be purchased separately Uniform Light and Air: The unique hollow light allows the air to circulate more efficiently; The special air-guiding designs incorporate angles that direct wind uniformly across the plant canopy; The wider LED coverage allows light to be distributed more evenly and reach more areas, creating better light conditions for plant growth Low Noise and Lasts for Ages: The combination of industrial-grade fans with dual ball bearings and optimized air inlets ensures that the AeroLight will run quietly; Our unique aluminum alloy heatsink fins increase the cooling area and extend the AeroLight's lifespan to approximately 70,000 hours
