Vivosun LumaRay 4-Bar Full Spectrum LED Grow Light | Red-Enhanced SGS Compatible
Looking to boost yield by giving your plants balanced lighting from all angles? The VIVOSUN LumaRay Side Lights (4-Bar) are engineered to illuminate areas your main grow light can’t reach—delivering powerful side and lower-canopy coverage that drives even growth and healthier development. Perfect as a supplemental lighting system, the 4-Bar model enhances photosynthesis efficiency while promoting dense flowering and fruiting.
The LumaRay Series offers scalable solutions for every grow setup—from the LumaRay Under Canopy Lights designed for precise ground-level lighting, to the larger LumaRay Side Lights (8-Bar) that cover broader canopies for commercial-scale use. Together, they form a cohesive ecosystem that maximizes light penetration, uniformity, and control across every layer of your grow.
Compact yet powerful, the LumaRay Side Lights (4-Bar) feature red-enhanced full-spectrum output, SGS smart control compatibility, and a durable gallium-nitride power supply. Whether you’re upgrading your tent setup or complementing your main fixture, these side bars deliver professional-grade performance in a flexible, easy-to-install design.

Spectrum
The LumaRay 4-Bar delivers a red-enhanced full spectrum output with a 60% red ratio (600–700nm), specifically formulated for side and under-canopy supplemental lighting. The elevated deep red energy drives photosynthetic activity in shaded lower bud sites, accelerating flowering and fruiting in areas that overhead fixtures typically can't reach — delivering 2.75 µmol/J efficiency across every bar for meaningful yield gains without significant additional heat load.

FAQs
The LumaRay 4-Bar system provides targeted side lighting to reach lower canopy areas that overhead fixtures often miss, improving light penetration and yield uniformity throughout the plant.
Yes — the LumaRay 4-Bar is SGS-compatible, allowing remote dimming, scheduling, and smart app control when paired with an SGS E42A or E25 controller (sold separately).
Yes — multiple bars can be daisy-chained using the RJ11 ports for simplified connectivity and broader coverage across your grow space.
Absolutely. The full-spectrum + 660 nm deep-red output supports vegetative, flowering, and fruiting stages with balanced intensity and color ratio.
Use the included magnetic clamps or tent-pole brackets to mount the bars horizontally along the sides of your grow area for even canopy coverage and easy height adjustment.
