VIVOSUN VS1000 LED Grow Light: 100 W Specs and Coverage

The VIVOSUN VS1000 is a documented 100 W LED board with dimming and a compact target growing area. The manufacturer's flowering coverage claim is about 2-by-2 feet, not a guarantee that every crop or mounting height will perform well there. Use a verified model-specific PPFD map to decide whether it fits your plants.

What VS1000 means

The VIVOSUN product page identifies real input power as 100 W, mixed white/red LEDs and a dimmer. The 'VS1000' label does not mean it draws 1000 watts. The maker also quotes approximate 11.8-inch-square dimensions and a flowering footprint smaller than its vegetative claim. Specifications can vary across generations, so verify the SKU printed on the product before buying.

Canopy coverage and intensity

Compare the manufacturer's PPFD map at the actual mounting height, not a promotional image of a glowing panel. A square fixture can produce more light in the middle than near plant edges. Seedlings and established high-light crops may require different output levels. Observe stretched growth as a possible sign of inadequate light, or bleaching near the fixture as a possible sign of excessive intensity.

Dimming and spectrum

The VS1000 is marketed with full-spectrum white/red output and several dimmer positions. White LEDs help gardeners see leaf color normally, unlike a strongly purple fixture. The manufacturer's 'low heat' description does not mean the driver and metal body remain cool enough to cover or touch. Keep ventilation around the housing and obey specified suspension distances.

How much electricity does it use?

At 100 W actual draw and 14 hours of operation, the fixture uses approximately 1.4 kWh per day at full output. Actual dimmed use may be lower. Multiply by your utility tariff for an estimate. Plants also respond to the amount of light reaching their leaves, not electricity consumed alone. A timer should provide a regular night period appropriate to the species.

Verdict and transparency

The VS1000 is worth comparing for a small high-light canopy, though a single ordinary houseplant may need a smaller bulb. Verify the exact product's coverage, electrical compatibility, mounting kit and warranty directly. This is a documentation-based feature assessment, not evidence of personal testing or an independently verified harvest result.

Before choosing a fixture

Identify the crop and plant canopy dimensions before looking at model numbers.
Confirm the exact wattage, PPFD map, safe hanging height and electrical rating.
Check the genuine warranty and controller or accessory compatibility.
Follow an appropriate light/dark schedule and monitor new growth.
