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.
Robin from Cascadia Greens joins us to see how our Active Grow T5 HO LED Grow Lamps perform in an indoor hydroponic rack grow light spectrum test for Basil, Shiso, Sorrel & Edible Flowers.
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.
Sustainable Horticultural Lighting
Replaces 54W T5 HO 4FT fluorescent lamps. Uses 60% 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.
The lamp’s transparent PC body protects against water damage and shattering without sacrificing photon output.
Long Lifetime & Guarantee
Features an exceptional 30,000-hour lifetime and a 1-year warranty. Active Grow is locally based in Seattle, WA providing same day response and friendly support.
All lamp components and manufacturing processes meet the highest industry safety standards.

Upgrading to T5 LED grow lamps from T5 fluorescents offers numerous benefits for plant growth and cost savings. With a longer lifespan and dedicated horticultural spectrums, LED lamps are more energy efficient, emit less heat and are environmentally friendly.
Learn about the T5 HO 2.0 LED Grow Light. The all-PC body provides growers with a lightweight (5.6 lbs), low-profile (1.7”) and high-performance LED fixture with 10% higher PPFD output than the previous generation.
I’ve been using your LED’s for about 3-4 years now and I am real happy with their performance/watt. I am able to produce some chunky colas from the canopy, uncommon under such a low watt light fixture. Taylor knew there was a huge demand for high performing T5’s while being discrete, and he delivered. These 120 watt T5’s pack a punch and get the job done while barely denting the pocketbook. These lights excel in a limiting environment such as a bedroom closet. A must have for all home-hobby growers.
Active Grow LED lights are killing it
Love these light fixtures and bulbs. Recently converted from a ballast based fixture due to a failed ballast. Active Grow honored the warranty and we converted to the new ballast bypass bulbs. The conversion was pretty simple and our fixtures are back in production. We grow lettuces in a ZipGrow hydroponic system (hanging light fixtures vertically in front) and our microgreens. Awesome response from our plants. These bulbs are amazing. Definitely worth the investment - especially with a company that honors their warranties and has fantastic customer service!
Plants already took positive changes going from fluorescent to led..worth the investment
My micros are essentially self growing and super tasty. We live in remote Alaska and it is a relief to find lights that can give us fresh produce without spiking our power bill.
I ha e now replaced all of my T2 florescent bulbs with your sun white LED lamps in my orchid room. My orchids are responding very well with a flush of new growths and blooms. And, my electric bill shows a substantial savings.
I bought these to replace T5 fluorescent tubes used for growing orchids. The conversion of my fixtures seemed daunting at first, but is actually very easy. I have been using them for over a month, and my plants are thriving and blooming well. I have calculated that these will pay for themselves in electrical cost in a little over 3 yrs.
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.
