Great replacement grow light, fantastic customer service. I bought these lamps to replace some very old fluorescent tubes that I use to keep some outdoor plants alive over winter. I hesitated first at the price, but after reading and studying I decided to go for it. After they arrived, retrofitting the old fixtures with new tombstones was a piece of cake. It was a great feeling to see the fixtures plugged in for the first time again and WOW how bright that light was! I'm sure my plants will love these. Unfortunately, one of the bulbs that arrived didn't work. I contacted Active Grow on a Friday evening, and within just a couple of hours Taylor responded to say he would send a replacement out on Monday. Now that's fantastic customer service! The new bulb arrived perfectly and works like a charm. Don't hesitate to buy these lamps. They're definitely brighter and more energy efficient than the old fluorescent tubes, and you'll notice a difference right away. Thanks Active Grow!!

Buy these. The 4 lights arrived promptly. They were very well packaged. I used these light to replace 4 older T12 florescent lamps. Following the directions that came with the lamps for removing the ballast was easy. I rewired 2 lamp fixtures using some wire nuts that I had on hand. These lamps seem to be about twice as bright as the older florescent lamps.

Great for Orchids. I swapped out my old T5 and T8 fluorescent tubes for Active Grow full spectrum LED lights about a year ago in all of my orchid growing stands. The results a year later are better than I could have expected the light quality is excellent and I'm blooming orchids that I was never able to bloom under fluorescents. Growth has been fantastic larger, more vigorous growths and great roots. Highly recommended!
