An 840 W spider-style horticultural LED fixture for professional indoor cultivation. It is positioned for larger controlled-environment lighting setups.
€525
The UPLUX LED 840W Spider Pro is engineered for high-density cultivation environments where maximum photon output, spectral fidelity, and operational reliability are paramount. With a nominal draw of 840 W and a premium full-spectrum output designed to encompass UV-A through far-red wavelengths, this fixture is built for both intensive commercial grows and professional research setups.
Featuring a “spider” style architecture with folding wings, it allows broad canopy coverage, deep canopy penetration and uniform light distribution — eliminating hotspots and enhancing crop uniformity. The passive cooling construction ensures silent, maintenance-free operation, while rugged components support 24/7 use in controlled environments.
Ideal for growers seeking high yields per square metre, predictable lighting schedules, and efficient energy use, the UPLUX LED 840W converts power into meaningful biological performance. It’s not just a grow light—it’s a cultivation instrument for serious operations.
Applications
