Who This Is For

  • You are adding side lighting because your main overhead fixture cannot penetrate the dense lower canopy layers.
  • You are installing supplemental bars because your lower flowers are underdeveloped compared to the top of the plant.

What We Found

  • The prism optics do a great job of cutting down on glare when you are working under the bars at eye level.
  • The GaN power supply runs noticeably cooler than older drivers, which helps manage heat in smaller tents.

What Users Say

  • Users who added these to their tents report that lower branches now produce the same density as the canopy tops.
  • Operators who struggled with shaded spots saw a significant increase in overall biomass after installing these bars.

Can these lights be controlled remotely? +

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).

Do the LumaRay lights support daisy chaining? +

Yes — multiple bars can be daisy-chained using the RJ11 ports for simplified connectivity and broader coverage across your grow space.

Are these lights suitable for all growth stages? +

Absolutely. The full-spectrum + 660 nm deep-red output supports vegetative, flowering, and fruiting stages with balanced intensity and color ratio.

How should I mount the LumaRay 4-Bar lights in my grow tent? +

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.
