VIVOSUN LumaLight 320W LED Grow Light | Full Spectrum, Deep Canopy Penetration & 3x3 ft Coverage

Product Introduction

TheVIVOSUN LumaLight 320W LED Grow Light is a full-spectrum bar-style indoor grow light designed to deliver strong, even illumination across approximately3 x 3 ft coverage, equivalent to roughly91 x 91 cm. It is well suited to medium-sized grow tents and indoor growing spaces where broad canopy coverage and deeper light penetration are important.

Rated at320W, the LumaLight uses VIVOSUN'sMicro-Lens Optic System, combining precision-curved and wave-shaped optics to concentrate and redistribute light across the canopy. For the exact 320W model, VIVOSUN specifies a PPFD of869 µmol/m²/s at 12 inches and light uniformity of up to0.89, helping reduce concentrated hot spots and provide more consistent illumination from the centre towards the edges of the growing area.

The fixture produces a balanced full spectrum using3000K and 5000K white LEDs together with 660nm deep red and 730nm far-red wavelengths. It is also compatible with theVIVOSUN GrowHub smart control system, allowing remote dimming, lighting schedules and app-based control when paired with a compatible GrowHub controller.

Smart GrowHub Control

TheVIVOSUN LumaLight 320W is designed to integrate with the wider VIVOSUN Smart Grow System for growers who want greater control over indoor lighting schedules and intensity.

When connected to a compatibleVIVOSUN GrowHub controller, the LumaLight can be managed through theVIVOSUN App, allowing growers to remotely adjust light intensity and automate lighting schedules.

The smart system provides a practical way to organise lighting around different stages of indoor plant development while reducing the need for repeated manual adjustments.

Manual and GrowHub dimming provides25%, 50%, 75% and 100% settings plus OFF, while VIVOSUN App control supports adjustable output from25% to 100%, plus OFF.

Temperature, relative humidity and VPD monitoring should not be advertised as functions included with the light itself because the required environmental sensing equipment is not supplied with this fixture.

LumaLight 320W Full-Spectrum LED Grow Light

Lighting is supplied by theVIVOSUN LumaLight 320W / VSL-LLB320, a bar-style full-spectrum LED grow light designed specifically for approximately3 x 3 ft indoor grow coverage.

The LumaLight uses a scientifically arranged multi-bar layout to distribute light across the growing area. VIVOSUN specifies canopy light uniformity of up to0.89, helping reduce hot spots and provide more balanced illumination across plants.

ItsMicro-Lens Optic System uses curved and wave-shaped optics to concentrate useful light while spreading it evenly across the canopy. VIVOSUN states that the optical system can increase PPFD by up to 20% while directing light deeper into plant growth.

The fixture produces afull-spectrum output using3000K and 5000K white light, 660nm deep red and 730nm far-red LEDs. This combination is designed to provide useful wavelengths through multiple stages of indoor plant development.

For the exact LumaLight 320W model, VIVOSUN specifies a PPFD of869 µmol/m²/s at 12 inches.

Manual or GrowHub dimming provides25%, 50%, 75% and 100% settings plus OFF, while VIVOSUN App control supports adjustment from25% to 100%, plus OFF.

The fully sealed light bars carry anIP65 protection rating, helping protect the LEDs from dust, mist and moisture exposure. Integrated aluminium heatsink fins assist with passive thermal management, while VIVOSUN specifies aQ90 rated lifespan of up to 36,000 hours.

Grow Tent Compatibility

The LumaLight 320W is designed to provide lighting coverage for approximately a3 x 3 ft growing footprint, making it particularly suitable for medium-sized indoor grow tents and similarly sized growing areas.

A 3 x 3 ft footprint is approximately91 x 91 cm, while the light fixture itself measures approximately65 x 65 x 7.4 cm.

Its square multi-bar construction helps spread overhead illumination across the canopy while leaving surrounding space for inline extraction, carbon filtration and other environmental-control equipment.

Because the LumaLight uses passive heatsink cooling rather than an integrated circulation fan, growers using the fixture inside an enclosed tent should provide suitable grow-space ventilation according to their overall setup.

Grow tent not included.

Because this listing is for the LumaLight fixture only, grow tent canvas, reflective Mylar, steel framing, duct openings and other tent components do not form part of this product.

Passive Heat Management

The LumaLight 320W uses afanless passive cooling design rather than the integrated circulation fan found on VIVOSUN AeroLight models.

Integrated heatsink fins help dissipate excess heat from the LEDs and internal components while avoiding additional fan noise from the lighting fixture itself.

This design keeps lighting and grow-space ventilation as separate systems, allowing growers to select an inline extraction fan and circulation equipment appropriate for their tent size and growing environment.

Mechanical ventilation or cooling should be used where required to keep the growing environment within the operating temperature range specified by VIVOSUN.

Cooling & Ventilation Details

Cooling Type: Passive aluminium heatsink fins
Integrated Circulation Fan: No
Inline Extraction Fan: Not included
Carbon Filter: Not included
Ventilation Ducting: Not included

The LumaLight's passive heatsink manages heat generated by the fixture itself but should not be treated as a replacement for suitable grow tent ventilation and environmental control.
