Mars Hydro FC3000 300W Full Spectrum LED Grow Light

The Mars Hydro FC3000 300W Full Spectrum LED Grow Light is a high efficiency bar style fixture designed for indoor gardens that need strong output, uniform canopy coverage, and flexible control across a 3 x 3 foot growing area. Built with Bridgelux 3030 white LEDs and upgraded OSRAM 660nm deep red diodes, the FC3000 delivers a balanced full spectrum for seedlings, vegetative growth, flowering, and fruiting.

Drawing 300 watts, the fixture produces up to 855 µmol/s PPF with a rated photosynthetic photon efficacy of 2.85 µmol/J. Its multi bar layout spreads the diodes across a larger surface area than a compact board style fixture, helping reduce central hotspots and create more even PPFD from the middle of the canopy to the outer edges.

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

The FC3000 is designed for 3 x 3 foot personal cultivation coverage and more intensive 2.5 x 2.5 foot commercial coverage. The detachable frame simplifies transport, storage, setup, and servicing while retaining the open bar structure needed for effective passive cooling.

A built in dimmer allows output to be adjusted as plants develop. Smart features are available when the fixture is paired with a compatible Mars Hydro controller, adding app based dimming, automatic schedules, sunrise and sunset simulation, and remote lighting management.

Bridgelux and OSRAM LED Technology

The FC3000 combines Bridgelux 3030 white LEDs with upgraded OSRAM 660nm deep red diodes.

The white LEDs provide broad spectrum output for complete cycle growth, while the dedicated OSRAM red diodes strengthen flowering and fruiting support without requiring a separate supplemental fixture.

Uniform Bar Style Coverage

The multi bar layout distributes light across the full fixture instead of concentrating output in the centre.

This design helps create a more even PPFD map, reduce hotspots, improve edge coverage, and support more consistent plant development throughout the growing area.

Full Spectrum Plant Lighting

The FC3000 produces a balanced spectrum using approximately 2800K to 3000K warm white, 4800K to 5000K cool white, and 660nm to 665nm deep red wavelengths.

This combination supports seedlings, leafy growth, flowering plants, herbs, vegetables, and fruiting crops under one fixture.

Efficient 300W Output

With a 300 watt power draw, the FC3000 produces up to 855 µmol/s PPF and reaches a rated fixture efficacy of 2.85 µmol/J.

It is designed for maximum 3 x 3 foot coverage, with a more concentrated 2.5 x 2.5 foot core footprint for applications that require higher light intensity.

Dimming and Smart Control Compatibility

The integrated dimmer allows growers to reduce output for seedlings and younger plants, then increase intensity as the canopy develops.

When paired with a compatible Mars Hydro smart controller, the FC3000 can support app based control, automatic schedules, remote dimming, lighting groups, and sunrise and sunset simulation. Smart controllers are optional and sold separately.

Detachable Frame Design

The FC3000 features a detachable frame that makes the fixture easier to handle, store, ship, and service.

A straightforward assembly process is required before use, with the necessary tools and instructions included.

Quiet Passive Cooling

The open bar layout and wave shaped aluminum heat sinks release heat without relying on cooling fans.

This silent design reduces maintenance, eliminates fan noise, and helps the fixture operate reliably in grow tents, grow rooms, and enclosed horticultural spaces.
