VIVOSUN T5 Grow Light 4-Tube 4ft 216W (6500K) High-Output Fluorescent, Dual-Switch & Daisy-Chain Ready

VIVOSUN T5 Grow Lights is a 4-tube, high-output fluorescent fixture delivering up to 20,000 lumens across 4ft tubes (5000 lumens per tube) with dual switches and 6500K daylight spectrum for indoor plant growth.

This high-output T5 fixture from VIVOSUN combines four 54W 6500K fluorescent tubes in a low-profile housing with reflective aluminum to push more light onto canopy-level plants while using less energy than bulky HID systems. The fixture ships pre-assembled and includes an 8 ft grounded cord, two hanging cables, and plug-to-plug expandability so you can daisy-chain units for larger setups. Tubes are rated for 20,000 hours, and the unit includes UL certification and warranties for peace of mind.

How does the VIVOSUN T5 deliver bright light without high energy bills?

The VIVOSUN T5 uses High-Output (HO) fluorescent tubes and a highly reflective powder-coated housing to maximize usable light while keeping wattage efficient. Its design spreads light evenly across a wider area compared with individual bulbs, reducing hot spots and wasted output.

• Four 54W HO tubes totaling 216W for efficient lumen-per-watt performance.
• Reflective aluminum housing rated 95–97% reflectivity to direct light downward.
• 5000 lumens per 4ft tube (up to 20,000 lumens per fixture) for canopy coverage.
• Low-profile form for close positioning without heat stress on plants.

What control and spectrum options are available for different growth stages?

Two independent on/off switches allow quick selection of light intensity and partial or full tube operation. Use fewer tubes for seedlings and early veg, then enable all tubes for larger vegetative growth to balance energy use with crop needs.

• Dual-switch layout: run 2 tubes or all 4 tubes to vary output.
• 6500K daylight spectrum suited for vegetative growth and seedlings.
• Easy manual switching—no ballast programming or dimmers needed.
• Expandable: plug to another fixture for scalable coverage and consistent spectrum.

How simple is installation and expansion for a home or commercial grow area?

The fixture arrives pre-assembled with hanging cables and a long grounded cord to make setup fast. It’s compatible with typical indoor grow rigs and can link to adjacent fixtures via plug connectors so you can build continuous light arrays.

• Pre-assembled fixture with two hanging cables attached at corners.
• 8 ft grounded power cord for flexible placement relative to outlets.
• Interconnectable plugs let you daisy-chain multiple units safely.
• Three hanging styles supported to adapt to different grow structures.

What reliability and safety features should I expect?

VIVOSUN provides long Tube life and warranty coverage plus UL certification for safe operation. The tubes are rated for extended use and the fixture’s robust packaging protects components during shipping.

• Tubes rated for about 20,000 hours of useful life.
• Fixture-level two-year warranty; bulbs covered by a one-year warranty for early issues.
• UL certified electrical safety for indoor use.
• Sturdy retail packaging minimizes transit damage.

Who is this for: Growers looking for an energy-conscious, easy-to-install lighting solution for seedlings, clonal racks, and vegetative benches will appreciate the VIVOSUN T5. It’s ideal for hobbyists and small commercial operations that need even canopy illumination, flexible control without complex electronics, and a scalable fixture they can add to as their footprint grows.
