This all-natural light spectrum boosts healthy growth rates for house plants, microgreens, flowers, fruits and more. By mimicking sunlight conditions with a high CRI of 95, the Sun White Spectrum will make your garden look more vivid and it will be easier to detect pests and deficiencies before they spread. This truly full-spectrum light extends beyond the traditional PAR range (400-700 nm) to include far-red wavelengths that increase photosynthesis rates via the Emerson Effect.

Bypass the Hassle
This ballast bypass LED grow lamp works with existing T5 fluorescent light fixtures by bypassing the ballast and wiring the lamp holders (tombstones) to a single end. Without the need for a ballast, these universal voltage 120-277V lamps do not flicker, buzz or experience longevity issues. *Requires bypassing the ballast during installation. Requires non-shunted lamp holders (tombstones). Please refer to the T5 LED GROW LIGHT BYPASS BALLAST INSTRUCTIONS VIDEO below for detailed installation steps.
