  • Sun White or Red Bloom Spectrum

Choose between the Sun White Spectrum with a high CRI that mimics natural sunlight conditions and the Red Bloom Spectrum which is focused specifically on 445 nm blue and 660 nm red wavelengths

  • Bonus Features

Features an extra-long 30,000 hour lifetime, 40% less heat output than fluorescent lamps and does not contain mercury

  • Typical Applications

Commercial vertical farm or home grow racking systems for micro greens, cannabis propagation, germination and tissue culture

Technical Information

Grow Like a Pro

Product introduction

The Active Grow T8 High Output 22W 4FT LED lamp replaces T8 32W and T12 40W 4FT fluorescent lamps and features increased PPF output, lower power consumption and 100% more effective spectrums for plant growth. The T8 LED lamp has a 190° beam angle for wide light distribution and runs cool, so it can be placed closer to plants and save space.

Energy Saving

Uses 40% less energy than fluorescent lamps and bypasses the ballast to save more amperage

Efficient PPF Output

Features a high total photon PAR (400-700nm) output of 41 μmol/s (Sun White Spectrum) – 33 μmol/s (Red Bloom Spectrum)

Bypass Installation

Works with existing fluorescent fixtures and requires the user to bypass the ballast by re-wiring to single-ended power

Sun White or Red Bloom Spectrum

Choose between the Sun White spectrum with a high CRI that mimics natural sunlight conditions and the Red Bloom spectrum which is focused specifically on 445 nm blue and 660 nm red wavelengths

Extra Long Lifetime

Features an extra-long 30,000 hour lifetime

Low Heat Output

40% less heat output than fluorescent lamps

Does Not Contain Mercury

Active Grow Spectral Analysis

Active Grow Spectrums are designed specifically for plant growth and feature the latest phosphor chip technology to help cultivators dial in the perfect light recipe for various plant species.

  • Sun White Spectrum -Bring the sunlight indoors with the Active Grow Sun White Spectrum that features 15+ higher CRI than traditional fluorescents and other LED lamps. This light covers the majority of the PAR (400-700 nm) spectral range. The high CRI light also makes it easy to see the plant’s vivid colors and any issues with plant development. Mix and match with the Red Bloom Spectrum lamps and create the ideal growing conditions for your home or commercial grow operation.
  • Red Bloom Spectrum -Boost chlorophyll light absorption with the Active Grow Red Bloom Spectrum that features dedicated 445-450 nm (blue) and 660 nm (red) light for flowers, fruits, germination and cloning. Mix and match with the Sun White Spectrum lamps and create the ideal growing conditions for your home or commercial grow operation.

Fluorescent Fixture Retrofit Instructions

Watch the video to learn the steps it takes to bypass a standard T8/T12 fixture’s ballast by wiring directly to single-ended 120-277 volt circuits. Bypassing the ballast helps not only lower wattage, amperage and heat output but avoids flickering, buzzing, longevity issues and other problems associated with ballasts.

Active Grow T8 LED Grow Lights Vs. T8/T12 Fluorescent Tubes - Energy, Spectrum & PPFD

These tests were taken to compare Active Grow 22W T8 HO 4FT LED Horticultural Lamps and 32W T8 4FT fluorescent lamps in a 2 tube T8 fixture. The test focuses on three main areas: Energy Consumption, Spectral Analysis & PPFD Coverage.
