VIVOSUN LumaLight 750W LED Grow Light | Full Spectrum, Deep Canopy Penetration & 5x5 ft Coverage

Product Introduction

TheVIVOSUN LumaLight 750W LED Grow Light is a high-output full-spectrum bar-style grow light designed to provide broad, even illumination across approximately5 x 5 ft coverage, equivalent to roughly152 x 152 cm. It is well suited to larger indoor grow tents and growing spaces where strong canopy coverage and deeper light penetration are important.

Rated at750W, the LumaLight uses VIVOSUN'sMicro-Lens Optic System, combining precision-curved and wave-shaped optics to concentrate useful light while distributing it evenly across the growing area. For the exact 750W model, VIVOSUN specifies a PPFD of900 µmol/m²/s at 12 inches and canopy light uniformity of up to0.89, helping reduce hot spots and provide more consistent illumination from the centre towards the edges of the canopy.

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, automated lighting schedules and app-based control when paired with a compatible GrowHub controller.

Smart GrowHub Control

TheVIVOSUN LumaLight 750W is designed to integrate with the wider VIVOSUN Smart Grow System for growers who want greater control over lighting intensity and schedules.

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

This provides a convenient way to adapt lighting output for different stages of indoor plant development without relying entirely on manual adjustments at the fixture.

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 hardware is not supplied with this fixture.

LumaLight 750W Full-Spectrum LED Grow Light

Lighting is supplied by theVIVOSUN LumaLight 750W / VSL-LLB750, a large multi-bar LED grow light designed specifically for approximately5 x 5 ft indoor grow coverage.

The scientifically arranged light-bar matrix is designed to spread illumination evenly across a broad plant canopy. VIVOSUN specifies light uniformity of up to0.89, helping minimise intense central hot spots while maintaining useful lighting towards the edges of the recommended coverage area.

ItsMicro-Lens Optic System combines precision-curved lenses with wave-shaped optics. This system concentrates and redirects useful light while spreading illumination across the canopy and improving penetration into lower growth. VIVOSUN states that the optical design can boost PPFD by up to 20%.

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

For the exact LumaLight 750W model, VIVOSUN specifies a PPFD of900 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 heatsink fins provide passive thermal management, while VIVOSUN specifies aQ90 rated lifespan of up to 36,000 hours.

Grow Tent Compatibility

The LumaLight 750W is designed to provide lighting coverage for approximately a5 x 5 ft growing footprint, making it particularly suitable for larger indoor grow tents and similarly sized growing areas.

A 5 x 5 ft footprint is approximately152 x 152 cm, while the light fixture itself measures approximately110 x 110 x 7.4 cm.

Its large square multi-bar construction helps spread overhead illumination across a broad 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 the requirements of their complete indoor growing 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 750W uses afanless passive cooling system rather than the integrated circulation fan found on VIVOSUN AeroLight models.

Integrated heatsink fins help dissipate excess heat generated by the LEDs and internal components without requiring a fan built directly into the lighting fixture.

This approach keeps lighting and grow-space ventilation as separate systems, allowing growers to choose an inline extraction fan, carbon filter and circulation equipment appropriate for the size and configuration of their grow space.

Mechanical ventilation or cooling should be used where required to maintain suitable operating conditions inside an enclosed grow tent.

Cooling & Ventilation Details

Cooling Type: Passive heatsink fins
Integrated Circulation Fan: No
Inline Extraction Fan: Not included
Carbon Filter: Not included
Ventilation Ducting: Not included
Smart Lighting Control: GrowHub compatible
App Lighting Control: Supported through compatible GrowHub setup

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