THROUGH THE Cultivator's LENS Highlights

  • You are upgrading your indoor lighting setup because traditional fluorescent fixtures leave you struggling with weak plant growth or inconsistent harvests.

  • The 200W power draw replaces 432W fluorescent fixtures while consuming 54 percent less energy.
  • The ballast free design eliminates buzzing and flickering while keeping light output reliable.
  • The Sun White Spectrum includes far red wavelengths to trigger the Emerson Effect for higher photosynthesis rates.

  • Growers who swapped out their old fluorescent fixtures report they no longer deal with ballast failures that once halted their progress.
  • Users managing these lights in tent setups say they have more control over canopy density by using the dual switch to dim light intensity.

FAQs

Can I use this for all stages of plant growth?+

Yes, the Sun White spectrum and dual switches make it ideal for both vegetative and flowering stages, providing the necessary wavelengths for every phase of development.

How many units can I daisy chain together?+

You can connect up to 4 units on a standard 120V circuit or up to 8 units on 208V-277V circuits, allowing for easy expansion in larger grow rooms.

Does this light require a separate ballast?+

No, this fixture features a ballast-free design. It uses ballast-bypass LED lamps, which eliminates the common failures, buzzing, and flickering associated with traditional T5 ballasts.

What is the recommended hanging height?+

We recommend a hanging height of 12-24 inches above the plant canopy. For high-light plants like cannabis, 12 inches is optimal, while 24 inches is suitable for leafy greens or seedlings.

Is the Sun White spectrum better than standard LEDs?+

The Sun White spectrum is superior because it features a high 95 CRI and includes far-red wavelengths. This triggers the Emerson Effect for faster growth and makes it much easier to see the true health of your plants.
