Better Light Spectrums = Better Plant Growth
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.
Amelia from Amelia’s Indoor Garden gives a 6-week update on using Active Grow T8 HO LED Grow Lamps for growing vegetables indoors.
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
The ClearSync protective film improves water resistance and prevents glass 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.

Corey from CoreysCave reviews the Active Grow T8 HO LED Grow Lamps for growing microgreens indoors.
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
I purchased the red bloom and I must say the light is very nice and stays cool, will be purchasing the Sun white pro to take place of my mars hydro. Really enjoying the lights right now, will keep an update. 4 stars just because I had to swap tombstones but I love these bulbs right now.
Thanks Active grow for your time and efforts for our plants to stay strong.
Your plants need these bulbs! Replacing LED daylight bulbs (not grow light) with these. Plants are starting to get greener and look healthier. So far so good. Packaging to protect bulbs during shipment was absolutely amazing. All working perfectly. Plan to order more soon.
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.
Very happy with the lamps. Easy to install and my plants love it!!
As advertised. great value
Houseplants love it. Sturdy construction that provides warm light for houseplants. Really brightened up the basement.
Very well packed. Good instructions. All 4 tubes worked well and seemed quite bright.
