Vivosun VSFL4300 LED Grow Light Bar 430W – Full Spectrum Grow Light for Grow Tent 120×120 cm with Dimming & GrowHub App

The Vivosun VSFL4300 LED Grow Light Bar 430W is a powerful and energy-efficient full spectrum LED grow light designed for medium to large grow tents and indoor grow spaces. Thanks to its efficient bar construction, full 380–780 nm spectrum, and high light output, this professional grow light supports optimal photosynthesis and consistent plant development from seedling to flowering.

With effective coverage up to 150 × 150 cm during the vegetative stage and 120 × 120 cm during flowering, the VSFL4300 delivers even light distribution across the entire canopy. This ensures more efficient light utilization and allows plants to develop uniformly within the grow space.

The integrated 6-step dimming function allows precise adjustment of light intensity for each growth phase, while GrowHub compatibility enables smart control via the Vivosun App. This allows growers to easily adjust and monitor their lighting for a stable and efficient growing climate.

Powerful Full Spectrum LED Grow Light for Growth and Flowering

The broad full spectrum light range of 380–780 nm supports all key growth phases of plants. The combination of blue light, deep red, far red, UVA, and infrared helps plants utilize light more efficiently during both vegetative growth and flowering.

This ensures:

• stable and uniform plant development
• efficient photosynthesis
• better light distribution across the canopy
• consistent growth results in the grow space

The bar structure of the lamp also ensures more uniform light distribution than traditional panel lamps.

Ideal for Grow Tents up to 150×150 cm

The VSFL4300 is designed for growers looking for a reliable and powerful LED grow light for medium to large grow tents.

Recommended grow area:

• Flowering: up to 120 × 120 cm
• Vegetative: up to 150 × 150 cm

This makes the lamp ideal for grow tents such as:

• 120 × 120 × 200 cm
• 150 × 150 × 200 cm

Thanks to its efficient light distribution, the lamp is suitable for both hobby growers and professional indoor growing setups.

6-Step Dimming for Maximum Control

The integrated dimming function allows for precise adjustment of light output to match the plant's growth phase.

Available dimming levels:

• 40%
• 50%
• 60%
• 80%
• 100%
• EXT (external controller)

By adjusting the intensity, energy can be saved while plants still receive the correct amount of light.

Key benefits:

• smart control via smartphone
• easy dimming and adjustment
• monitoring of light settings
• more efficient management of larger grow spaces

With the daisy chain function, up to 160 lamps can be connected, making this lamp suitable for larger grow installations.

Efficient Bar Design with Optimal Heat Dissipation

The modern foldable bar design ensures efficient heat dissipation and uniform light distribution. This keeps the temperature around the lamp stable and extends the lifespan of the LED chips.

In addition, the lamp features a detachable power supply, which further improves heat dissipation and simplifies installation.

Design advantages:

• better heat dissipation
