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.

thank you for your awesome service and company.

Active Grow, thank you for your awesome service and company. I was happy to see your 8 tube lights which I will be ordering a few of them in the summer to start my seedlings and transplants indoors. My wife and I have a community homestead connection, we teach people how to grow organic veggies for their families. I have never purchased such amazing lights, my plants grow faster stronger and healthier than with natural sun in a greenhouse. I previously worked for the state of Virginia setting up greenhouses, gardens and environmental systems. I will recommend your products to the many people in our homestead connection and in my horticulture connections. Here is a picture of our fall 2023 transplants and current spring 2024 seedlings and transplants. We have over 1000 plants going into our Oasis in the spring. Enjoy the picture of our not finished desert Oasis. Thank you again.
Odinsson Oasis, and Community Homestead Connection.

I'm Gary Maale and I own Lone Star Mastiffs Farms. We grow 250 varieties of super-hot peppers. I have been using Active Grow grow lights for 2 years to start all my pepper plants during the winter. I also use them to grow my microgreens. I use two T5 4' 8 bulb lights to get plants to about 6" tall then I move them to an outdoor green house and start more. These lights have been critical in helping me get this business off the ground and I couldn't be happier with them.

Active Grow LED lights are killing it

Sturdy and working

Purchased on recommendation from a family member, this light arrived well-packed and in working order despite the rough treatment it received during transit. The boxes were damaged heavily and the housing was dented, but the light still works. It was also easy to assemble.

Michael Bechtold

I bought one to replace aging banks of fluorescent shop lights and the results were so good I bought another to replace high output biaxial lights for growing a mixed collection of orchids. Multiple new growths, better flowering and savings on electric bill? Yes please!




The product works great!


Grow vegetables indoors all year from seed to harvest using Active Grow sunlamps. I started out with the Active Grow SunWhite 8 lamp T5 fixture. My tomatoes, peppers, and cucumbers did so well that I decided to convert all my T8 fluorescent fixtures into ballast free to use T8 Active Grow SunWhite bulbs too (T8 review starts at 2:23). I have harvested so many awesome tasting vegetables. My lettuces did phenomenal under these grow lights. The hardiness and texture were way better than when I was using full spectrum fluorescent. Check out my YouTube videos at Amelia's Indoor Garden. To top it off they are located here in the US with excellent customer service. They truly have a passion for their product.
