Mars Hydro FC8000 800W Full Spectrum LED Grow Light

The Mars Hydro FC8000 800W Full Spectrum LED Grow Light is a commercial-grade bar-style fixture designed to deliver intense, uniform lighting across 4 x 4 and 5 x 5 foot indoor gardens. Built with Bridgelux 3030 white LEDs and upgraded OSRAM 660nm deep red diodes, it combines high photon output, complete-cycle spectral performance, precise dimming, and efficient passive cooling in one powerful fixture.

Drawing up to 800 watts, the FC8000 produces as much as 2,320 µmol/s PPF with a rated photosynthetic photon efficacy of 2.9 µmol/J. Its wide multi-bar layout distributes hundreds of diodes across the complete fixture, helping reduce central hotspots while providing more consistent intensity from the middle of the canopy to the outer edges.

The full spectrum combines warm white, cool white, and deep red wavelengths to support plants from propagation through harvest. Bridgelux 3030 white LEDs provide broad output for photosynthesis and healthy structural development, while OSRAM 660nm deep red diodes strengthen the spectrum used heavily during flowering and fruit production.

The FC8000 is optimized for intensive 4 x 4 foot core coverage and can illuminate a maximum 5 x 5 foot cultivation area. Its high-output design makes it suitable for large grow tents, dedicated grow rooms, vertical farms, single-level commercial gardens, and high-density production environments.

A built-in dimmer allows growers to match light intensity to each stage of development. Daisy-chain compatibility simplifies control across larger multi-light installations. Optional Mars Hydro smart controllers add app-based operation, automated lighting schedules, remote dimming, group management, and sunrise and sunset simulation.

The open bar structure and wave-shaped aluminum heat sinks dissipate heat without fans. This silent passive-cooling design reduces maintenance while helping create a more stable canopy environment.

Bridgelux and OSRAM LED Technology

The FC8000 combines high-efficiency Bridgelux 3030 white LEDs with upgraded OSRAM 660nm deep red diodes.

The Bridgelux LEDs provide broad-spectrum lighting for complete-cycle cultivation, while the dedicated OSRAM red output supports stronger flowering and fruiting without requiring a separate red supplemental fixture.

Uniform Bar-Style Coverage

The wide multi-bar layout spreads the LEDs throughout the fixture instead of concentrating output directly beneath its centre.

This design helps reduce hotspots, improve edge-to-edge uniformity, and deliver more consistent PPFD across large canopies.

Full Spectrum Plant Lighting

The FC8000 produces a complete spectrum using approximately 2800K to 3000K warm white, 4800K to 5000K cool white, and 660nm to 665nm deep red wavelengths.

This balanced output supports seedlings, vegetative growth, flowering plants, herbs, vegetables, and fruiting crops throughout their complete lifecycle.

High-Efficiency 800W Output

With an output of up to 800 watts, the FC8000 produces as much as 2,320 µmol/s PPF and reaches a rated fixture efficacy of 2.9 µmol/J.

It is designed for maximum 5 x 5 foot coverage, while the concentrated 4 x 4 foot core footprint is suitable for applications requiring greater canopy intensity.

Dimming and Daisy-Chain Control

The integrated dimmer allows output to be reduced for seedlings and younger plants, then gradually increased as the canopy develops.

Daisy-chain compatibility allows multiple compatible Mars Hydro fixtures to be adjusted together, simplifying larger grow rooms and commercial installations.

Optional Smart App Control

Smart functionality requires a compatible Mars Hydro controller.

When paired with an iConnect or iControl controller, the FC8000 can support app-based dimming, automated schedules, remote adjustments, fixture grouping, and sunrise and sunset simulation. Smart controllers are optional and sold separately.

Efficient Passive Cooling

Wave-shaped aluminum heat sinks and open spacing between the light bars allow heat to dissipate naturally.

The fanless design operates silently, eliminates moving components, and helps reduce maintenance over the fixture’s operating life.

Commercial and Multi-Tier Applications

The FC8000 is suitable for grow tents, dedicated rooms, vertical racks, hydroponic systems, and commercial cultivation environments.

Its high output and even distribution allow it to function as either the primary light source for a large canopy or part of a larger multi-fixture installation.
