Mars Hydro FC6500 730W Full Spectrum LED Grow Light

The Mars Hydro FC6500 730W Full Spectrum LED Grow Light is a high-output bar-style fixture designed for serious indoor cultivation in 4 x 4 and 5 x 5 foot grow spaces. Built with Bridgelux 3030 white LEDs and upgraded OSRAM 660nm deep red diodes, it delivers strong photon output, uniform canopy coverage, and complete-cycle spectrum performance for vegetative growth, flowering, and fruiting.

Drawing 730 watts, the FC6500 produces up to 2,117 µmol/s PPF with a rated fixture efficacy of 2.9 µmol/J. Its wide multi-bar layout spreads the diodes evenly across the fixture, helping reduce centre hotspots while improving edge-to-edge PPFD across large canopies.

The full spectrum combines warm white, cool white, and deep red wavelengths. Bridgelux 3030 LEDs provide broad-spectrum output for photosynthesis and healthy structural growth, while OSRAM 660nm deep red diodes strengthen the portion of the spectrum used heavily during flowering and fruit development.

The FC6500 is designed for 5 x 5 foot personal cultivation coverage and more intensive 4 x 4 foot commercial coverage. Its high-output design makes it suitable for larger grow tents, single-level production rooms, vertical farms, and multi-light commercial installations.

An integrated dimmer allows growers to adjust output as plants mature. Daisy-chain compatibility makes it possible to control multiple compatible fixtures together. Smart functions are available when the light is paired with an optional Mars Hydro controller, adding app-based control, automatic dimming, lighting schedules, sunrise and sunset simulation, and remote management.

The foldable frame simplifies installation, transportation, and storage. Wave-shaped aluminum heat sinks and open spacing between the bars provide passive cooling without fans, allowing the fixture to operate quietly while reducing maintenance.

Bridgelux and OSRAM LED Technology

The FC6500 combines efficient Bridgelux 3030 white LEDs with upgraded OSRAM 660nm deep red diodes.

The white LEDs provide broad-spectrum plant lighting across the complete growth cycle, while the dedicated OSRAM red output strengthens flowering and fruiting performance without requiring a separate red supplemental light.

Uniform 5 x 5 Coverage

The wide bar-style layout distributes light across the complete fixture instead of concentrating output directly beneath the centre.

This design helps reduce hotspots, improve outer-canopy coverage, and support more consistent growth across large indoor gardens.

Full Spectrum Plant Lighting

The FC6500 produces a balanced spectrum using approximately 2800K to 3000K warm white, 4800K to 5000K cool white, and 650nm to 665nm deep red wavelengths.

This spectrum supports seedlings, vegetative development, flowering plants, herbs, vegetables, and fruiting crops under one fixture.

High-Efficiency 730W Output

With a 730 watt power draw, the FC6500 produces up to 2,117 µmol/s PPF and reaches a rated fixture efficacy of 2.9 µmol/J.

Its output is suited to full 5 x 5 foot personal cultivation areas, while growers seeking greater canopy intensity can use it over a concentrated 4 x 4 foot production footprint.

Dimming and Daisy-Chain Control

The built-in dimmer lets growers reduce intensity for young plants and gradually increase output as the canopy develops.

Daisy-chain compatibility allows multiple compatible Mars Hydro fixtures to be controlled together, making the FC6500 suitable for both individual tents and larger multi-light grow rooms.

Optional Smart App Control

Smart functions require a compatible Mars Hydro controller.

When paired with an iConnect or iControl controller, the FC6500 can support remote app control, automated dimming, daily schedules, lighting groups, and sunrise and sunset simulation. Smart controllers are optional and sold separately.

Foldable Frame Design

The foldable construction makes the FC6500 easier to handle, transport, store, and install.

This design is especially useful for large fixtures that may need to pass through narrow doors or be moved between grow rooms.

Quiet 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 long-term maintenance.
