So good!
"As I upgrade my grow lights, I'm going all LEDs. This grow light has so much going for it. First off, it's long, so I can fit four flats directly under it. Secondly, it's slim (in terms of height), which is great because every inch counts. It also has a pleasing color temperature, so it's not an obnoxious typical LED-colored light if you need to be in the room with your grow lights. There are two switches so you can run it at half power or full power. There's also an auxiliary outlet on the side, which I didn't use but it's nice to know it's there if I have to daisy chain another light to it in the future. It runs cool and quiet, unlike some LEDs that have loud, obnoxious fans, so that's a huge plus. As for performance, it worked great. All of my seedlings grew very well and far better than under fluorescent lights, which can burn foliage because they have to be so close to the plants. This is an excellent light. I'd love to upgrade my entire system to this light."
So good...
"I've been using T5 HO lamps for a while now as my primary light source. I thought I had my spectrum close to dialed in with a mix of different lamps. I had my doubts. I decided to switch over to these T5 HO daylight LEDs and was quickly blown away by the response in my garden. Deeper greens, thicker leaves, tighter growth patterns, everything. The PPFD reading is much more even throughout the ENTIRE grow space as compared to my experience with traditional T5 HOs. I can now utilize the edges of my grow space instead of just focusing on the direct center under the lamps. Literally EVERYTHING is so much better then traditional T5s that I'll never go back again. The spectrum these lamps produce has been a total game-changer. Thank you Active Grow."
First Cattleya blooms
"Have had these for about three months and am now seeing the first buds on my Cattleya orchids, and most of the plants are pushing new growths and roots. I have three of these units installed in a small room. Could not have used regular T5HO as they would create too much heat in the small enclosed space (no natural light). But the T5LED's put out so little heat that the temps are manageable even in the small room. And since the lamps are not hot I can put the orchids just a few inches below the lamps. With fans and high humidity, the leaves stay cool and the plants stay hydrated. I measured about 1800 footcandles of continuous light a few inches below the lamps. Since the lamps are on 16 hours a day the Cattleyas are getting enough light for the first time and their growth is the proof. I could never have flowered these high-light kinds of orchids without lamps like this."

Q&A
- Is there hanging hardware included? Not seeing anything in the picture. Thank you.
- Hi Jackie, Thanks for your question! There are 2 built-in wire hangers on the Active Grow light fixture.
- Hello, Given that I've seen other LED products whose lights are built in and not replaceable, I wanted to see if these lights were indeed replaceable after so many years, so I wouldn't have to replace the whole fixture but just the individual 4' bulbs? Thank you!
- Hi David, The manufacturer does make and offer replacement lights and we will be adding these replacement lights to our product line this month!
- Does this come with any replacement lights besides the 4 it comes with?
- Hi Axistilt, The fixture contains 4 tube lights, but if you would like replacement lights, they are available for purchase here: https://www.harrisseeds.com/products/41695-4-active-grow-wide-spectrum-t5-ho-led-hort-tubes
