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 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 below for detailed installation steps.
Sustainable Horticultural Lighting
Replaces 32W T8/40W T12 4FT fluorescent lamps. Uses 45% less energy, greatly reducing heat output, HVAC costs and the need for more vertical space.
Plant Centric Design
Designed specifically for horticulture use with a 100% more effective spectrum for plant growth and a high PBAR (280-800nm) output and efficacy.
ClearSync Film Technology

We mainly use the grow lights for seed starting in March and growing during the winter. We use the lighting in the greenhouse this year because we were not getting enough sunny days and there was a lot of rain this year, so the LED lighting really made a difference. Thank you for your products they work great!
WARNING! If you use these bubs to grow plants, be advised you will need more room for your plants as they grow like crazy using these bulbs.
Exactly What I Wanted. I searched locally for this kind of light with no success. After weeks of researching, I finally settled on this product. With the constant source of light, I now have seedlings sprouting and I couldn't be happier.
I modified my existed older grow light setup by removing the ballasts and that went well. Taylor's instructional video was a big help. It's still early but I'm excited to see good results this year. I'm planning to modify my remaining setups.
Active Grow Great Customer Service. I purchased the Active Grow T8/T12 High Output - Plant Grow Lights for Indoor Plants, Germination & Microgreens - 22W - Sun White Full Spectrum High CRI 95! I purchased them in July but due to health was unable to try them till this November, Despite the best shipping container packaging I have ever seen two of the bulbs would not work. When I contacted Active Grow directly they were friendly and willing to send replacements immediately..! The product is very bright with superior specifications and exceeds our expectations! I can highly recommend them for both their great customer service and their quality product ! Looking forward to doing more business with them !!!
I wanted directly wired bulbs so that I didn't need to worry about ballast compatibility, I wanted full spectrum light, and I wanted to retrofit my existing fixtures rather than throwing them away and buying new ones. In a very extensive search, Active Grow bulbs were the only ones I found which met my criteria. I was a bit apprehensive about having to buy four bulbs sight unseen, but now that I have them I'm really pleased that I can retrofit two fixtures rather than just one (which was my initial plan).
Very bright bulbs. Easy to convert standard florescent fixture to LED to fit these bulbs. Very bright. Well packaged.
