Vivosun LumaLight 500W Full Spectrum LED Grow Light

The LumaLight 500W is purpose-built for a 4×4 ft canopy footprint. Its scientifically arranged light-bar matrix achieves up to 0.89 uniformity across that coverage area, ensuring plants along the perimeter receive comparable intensity to those directly beneath the fixture. For a 3×3 tent, the LumaLight 320W is the better-matched option.

The Micro-Lens Optic System uses two lens types working together: curved precision optics that narrow the beam angle for higher PPFD, and wave-shaped optics that diffuse light multi-directionally for deeper canopy reach. Combined, they boost PPFD by up to 20% over standard flat-lens designs, pushing more usable light to lower bud sites and improving development throughout the entire plant.

Yes — the LumaLight 500W operates fully as a standalone fixture using its onboard 4-level dimmer knob (25%, 50%, 75%, 100%). The VIVOSUN GrowHub (sold separately) is an optional upgrade that adds remote monitoring, automated lighting schedules, and stepless 25%–100% app-based dimming for growers who want hands-free precision control.

Yes — the IP65 waterproof and dustproof rating means the light bars are fully sealed against water spray from any direction and completely dust-tight. You can safely water plants, apply foliar sprays, or wipe down the fixture with cleaning solutions without risking component damage or reduced lifespan, making the 500W well-suited for high-humidity flowering environments.

The LumaLight 500W combines 3000K and 5000K white LEDs with 660nm red and 730nm far-red diodes to create a balanced full spectrum that supports every stage from seedling through harvest. The 660nm red accelerates flowering and increases yield, while the 730nm far-red regulates the photoperiod response and promotes larger leaves — no need to swap fixtures between growth phases.

The 500W carries a Q90 flux maintenance rating of 36,000 hours, meaning it retains at least 90% of its original light output for that duration. Running 18 hours per day, that exceeds 5 years of consistent performance. Integrated heatsink fins passively dissipate heat to protect LEDs and internal components from thermal stress across many grow cycles.

Yes. The LumaLight 500W accepts 120–240VAC input at 50–60Hz, making it compatible with both standard North American outlets and 240V setups common in commercial or multi-light installations. No voltage converter or adapter is required.

The LumaLight 500W is backed by VIVOSUN's 5-year after-sale service warranty, covering the fixture against manufacturing defects and ensuring long-term support for your growing operation — whether you're running a single tent or a multi-light setup.
