PhotonTek i850W Top Light Full-Spectrum LED 400V

The PhotonTek i850W Top Light Full-Spectrum LED 400V is a high-performance commercial horticultural LED fixture designed for large-scale indoor growing facilities. Combining powerful light output, excellent efficiency and an optimized full spectrum, this compact top light provides professional growers with reliable illumination throughout every stage of plant development.

Operating at 400V, the PhotonTek i850W delivers an impressive PPF output of up to 2295 µmol/s with an efficacy of up to 2.7 µmol/J. Its carefully balanced full-spectrum light output is ideal for indoor cultivation facilities where plants depend entirely on artificial lighting, providing effective light for both vegetative growth and flowering.

Designed as an efficient alternative to traditional 1000W HID lighting, the i850W can help commercial growers reduce energy consumption while maintaining high light intensity. PhotonTek states that facilities replacing existing 1000W HID fixtures may save up to 30% on energy, depending on the application and installation.

The fixture features premium Osram and Seoul Semiconductor diodes engineered for dependable performance and excellent light quality. Its 120° beam angle provides broad, uniform light distribution across the plant canopy, helping maximize usable light throughout the growing area.

For precise lighting management, the PhotonTek i850W is dimmable from 20% to 100% without sacrificing efficiency. It also supports 0–10V external control using a PhotonTek controller or compatible universal lighting controller, allowing growers to automate and adjust light intensity according to crop requirements.

The integrated passive cooling system uses intelligently spaced cooling fins to dissipate heat through natural convection without requiring additional fans. This reduces maintenance, noise, and mechanical components while supporting dependable long-term operation.

With its rugged IP65 protection rating, daisy-chain capability, and compact commercial design, the PhotonTek i850W Top Light Full-Spectrum LED 400V is an excellent lighting solution for professional indoor growing facilities that need powerful output, efficient operation, and flexible lighting control.
