Who This Is For

  • You are swapping out fluorescent tubes because high heat and power bills are making your garden too expensive to run.
  • You are moving to high-CRI lighting because you need to see true plant colors to spot pests before they cause damage.

What We Found

  • The 95 CRI makes spotting pests or mildew much easier than under lights that wash out the plants true colors.
  • The dual switches allow you to run just half the fixture for clones, which prevents light stress on young plants.

What Users Say

  • Growers who swapped their 432W racks for these say their power bill dropped while their plant vitality improved.
  • Users tell us they stopped pulling plants out of the tent to check them because the light shows true leaf color.

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.
