Serious plant grow lights for serious canopies. The MA400 doubles the MA200 formula – 400W of full-spectrum output with 0-100% dimming, silent passive cooling, and enough intensity to flower a 120x120cm space edge to edge.

A 400W quantum board designed around a 120 x 120 cm canopy

MA400 400W Quantum Board LED Grow Light

The MA400 is a full-spectrum quantum board for a 120 x 120 cm grow space where a compact 200W board no longer provides the intended flowering intensity. It balances meaningful output with a fanless, dimmable form factor.

Choose This Fixture for the Right Job

Use the 120 x 120 cm footprint as the primary planning point. A larger 150 x 150 cm area can receive lower-intensity coverage, but plant density, crop stage and desired results should determine whether that is appropriate.

120 x 120 cm tent

The central full-intensity use case for the MA400.

150 x 150 cm canopy

A lower-intensity or vegetative coverage option rather than a default flowering claim.

Expandable grow room

Confirm this expandable grow room plan against the listed footprint, mounting height and room conditions.

Verified canopy area

Size the fixture from the real growing footprint rather than the room name.

Why This MA400 400W Quantum Board LED Grow Light Fits Its Role

The MA400 is a full-spectrum quantum board for a 120 x 120 cm grow space where a compact 200W board no longer provides the intended flowering intensity. It balances meaningful output with a fanless, dimmable form factor.

Performance varies with plant stage, mounting height, daily light duration and the wider growing environment.

01

400W Rated Output

MA400 400W Quantum Board LED Grow Light is listed at 400W. Match runtime and output settings to the room, crop stage and available electrical capacity.

02

Approximately 1,080 µmol/s Stated PPF

The published product specification lists Approximately 1,080 µmol/s. Actual plant response still depends on hanging position, canopy condition and the wider growing environment.

03

Quantum board Layout

The published specification lists light format as Quantum board. Confirm that detail against the selected configuration before ordering.

04

Passive Thermal Management

The fixture uses Passive finned aluminium heatsink. Room airflow and extraction still need to manage the heat produced by the full lighting system.

Choose the Setup for Your Growing Space

Use the current WooCommerce selector and product details above the Add to cart button as the source of truth for the configuration being purchased.

Check Purchase Options

Set Up Before You Increase Intensity

Install only after confirming secure hanging points, the product selector, cable routing and ventilation. Start with a conservative height and output setting, then adjust from plant response rather than from a generic percentage. For repeatable schedules, use a compatible plug-in timer switch and keep electrical connections dry and accessible.

Confirm the physical growing footprint, mounting height, room extraction, available circuit and any controller or cable compatibility. The product selector and current listing are the source of truth for the purchasable configuration. Check the required plug, supplied hardware and cable length before committing to a layout.

This page describes the listed model rather than promising an outcome. Plant performance remains dependent on the crop, climate, watering, nutrition, canopy management and the way the fixture is installed.

For a smaller room, compare the MA200 full spectrum LED grow light before choosing 400W.

400W grow light FAQ

Answers to common questions about placement, compatibility, control and purchase options.

What tent size is the MA400 built around?

A 120 x 120 cm tent is its core high-intensity footprint.

Can it be dimmed for early growth?

Yes. Use the dimmer and appropriate hanging distance rather than exposing young plants to maximum output immediately.

Can it light 150 x 150 cm?

It may suit a lower-intensity or vegetative application there; it should not be treated as automatic full-flower coverage.

Does it have an onboard fan?

The product is listed with passive aluminium cooling rather than an onboard fan.

Can several MA400s be linked?

The listing identifies daisy-chain capability; check the intended controller and electrical setup before installation.
