Why Buy From Grow Tents Depot
  • What’s in the Box?:
  • 4x 22W T8 HO Ballast Bypass 4FT LED Grow Lamps
  • 1x Lamp installation guide
  • 2x Fixture modification stickers
  • What Can I Grow?: Ideal for use in commercial or home grow applications for vegetables (squash, peppers, legumes, carrots, etc.), fruits (tomatoes, citrus, strawberries, cucumbers, etc.), flowers (African violets, begonias, orchids, gardenias, etc.), tropical plants, carnivorous plants and for the flowering stage of growth.
  • Red Bloom Pro Spectrum: Pink light is power, and not a photon is wasted with this chlorophyll-boosting, full-spectrum light that hits precisely on 450 nm (blue) and 660 nm (red) wavelengths. This spectrum also features additional far-red light that increases plant photosynthesis rates via the Emerson Effect. Designed to increase plant mass, speed up plant growth and promote healthy carotenoid development, budding and fruiting.
  • Bypass the Hassle: This ballast bypass LED grow lamp works with existing T8 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 T8/T12 LED GROW LIGHT BYPASS BALLAST INSTRUCTIONS VIDEO tab for detailed installation steps.

    Easy to build your own design. I originally bought 88 lights and designed my first room and my plants are producing 4x as much as they were before. I couldn't be happier with these lights so i decided to buy 100 more and make another room. The staff at active grow are great to work with and had my order to me very fast. I will post pictures as soon as i can


    Very happy with the lamps. Easy to install and my plants love it!!


    Very Happy with these lights. the lights are amazing. No noise and no increase to my electricity bill. I have bought four sets of these now and I have not had one problem.
