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.

It's ALIVE! Works for me!!! Lite it, don't fight it!!!!

These seedlings I started about 5 weeks ago are now thriving in my garden. I usually supplement those plants with others I pick up at the nursery to fill in gaps. Not this year. Retail inventory of seedlings was horrible, and so was the quality! And my latest happy discovery this seed-starting round is my new grow lamp system. I love trying different lighting systems in hopes of finally settling on a favorite. Over recent years as I was creating my Master Seed-starting online course, I trialed many options from basic fluorescent shop lights, to high-end LED rigs and more sophisticated T5 fluorescent systems. Recently I was invited to try and keep (at no cost to me) a 24W T5 lamp and fixture from Active Grow. I've trialed several more basic LED shop light rigs in the past but the results were just average. But not this one. It's definitely got my attention. These lamps were clearly designed for indoor growing, with high PPF efficiency (the amount of quality light frequency usable by the plants), and higher energy efficiency (none of the heat energy wasted by the fluorescent alternatives). Over 5 weeks of growing time under this system, the plants performed very well - no legginess, nice compact plants, great color, and no light-burn. You can buy just the lamps that plug and play into existing T5 fluorescent fixtures (4 lamps cost about $139), or you can buy the lamps and fixture for around $219 for the 2x4 ft size - perfect for evenly lighting 4 standard trays on a self. The seedlings here were growing under the “Sun White Pro”� lamps and I was very happy with the results. I'm really looking forward to seeing how it performs for the next round of warm-season edibles starting in February. A link to this lamp system is in my instagram profile (@joegardener).
