The Lumatek i850w Top Light Full Spectrum 400v LED Grow Light is the perfect solution if you're looking for a high intensity and compact LED top light fixture to replace and upgrade HPS systems or to start a new large scale indoor project where canopy uniformity is key.
HPS Replacement
Introducing the i850W Top Light Full-Spectrum LED 400V, a cutting-edge, compact, and high-performance fixture meticulously engineered for indoor large-scale projects.
Whether you’re embarking on a new facility or seeking to replace existing 1000 W HID lights, this fixture offers an exceptional opportunity for up to 30% energy savings, amplified yields, and superior crop quality. With an impressive light output of up to 2295 µmol/s and an outstanding efficacy of up to 2.7 µmol/J (400 V AC), this LED system maximizes indoor crop productivity while significantly reducing operational costs.
Full Spectrum
Harnessing the power of a precisely balanced Full Spectrum, the i850W Top Light Full-Spectrum LED 400V is perfectly suited for growing facilities devoid of natural light. It provides optimal conditions for healthy plant growth across all stages of development. This innovative solution incorporates state-of-the-art diode technology, ensuring impeccable performance even when dimmed to as low as 20% without compromising efficiency.
Passive Cooling
One of the standout features of the i850W is its exceptional passive cooling system. Meticulously designed with high-quality components and intelligently spaced fin lines, this fixture facilitates the efficient dissipation of heat through convective airflow. As a result, it has minimal impact on facility air circulation while guaranteeing an extended lifetime with minimal maintenance requirements.
Because these high-intensity top light fixtures run off 400 volt commercial electricity supply, they're most suited to high-ceiling commercial warehouse applications.
Please note: These grow lights are designed for large-scale commercial horticultural applications, and thus can only be ordered as a minimum quantity of 100 units. Please contact us directly to purchase these fixtures and for accurate pricing.
