T8 HO 4FT LED Grow Lamp (40W Eqv.) – Red Bloom Pro Spectrum

Two of four arrived with broken glass
UPDATE 1-31-2025
I was contacted about the damaged bulbs and after photo confirmation, two new bulbs were sent.
Very happy that Active Grow stands behind their product.

These LEDs are very easy to install and have excellent light output for my micro greens and veges!

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.

Seedlings are doing great! Superior customer service!

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!

Perfect and hard workers. Absolutely in love with these lights. They are perfect grow lights and work extremely well. Customer service was a pleasure. One tube was broken during shipping and they had a new tube at my door within 48 hours. Will be my sole provider for grow lights in the future!

Change to non-shunted tombstones while rewiring. It was fun ripping out most of the wiring and ballasts in the old light fixtures. Very important to replace the tombstones in the fixture with non-shunted tombstones (search for that term on Amazon). Both non-wired and wired ones are available on Amazon. Need 4 of each for fixture. Great bulbs. Plenty of light and seem to be quality built. Vendor great to deal with. Light fixtures much, much lighter without the ballasts, thus much easier to reposition the fixtures.

Great purchase. Work great.

Great service, great bulbs. Super bright! Ballast bypass is super easy, if you're just moderately handy you can do this.
I'm growing my starts for the garden (tomatoes, peppers, etc) and upgraded to get better lighting than fluorescent, reduce heat, and now I don't have a ballast to replace, ever!
After I Bypassed the ballast and changed the tombstones one of the bulbs didn't come on. I sent an email and 5 minutes later my phone rang. It was the owner himself calling to apologize and offered to warranty right away. He asked if I flipped the bulb (power is only on one side) and I didn't try that yet. Boom, bulb works just fine. As I just did the bypass I should've figured this out myself but now I'm happy to know that I bought my bulbs from the right company. Super service and bulbs.

Works great. Good quality product.

Fantastic product and service. Retrofitted my T8 fixtures for my greenhouse. These amazing LED grow lights, full spectrum and red bloom, have produced excellent results. My seedlings are fabulous. They are packaged perfectly and the customer service is exemplary.

Was very happy with these lights and made a video review. I did a complete experiment with these lights on Microgreens. I own a small Microgreens farm and wanted to try something that uses less electricity than a conventional light. I was very happy with these lights and made a video review.

A+

Amazing grow light! I'm just starting out, but I have seen a strawberry ripen under a week and tasted amazing using these lights! I germinated many types garden vegetables also a bean plant 8' tall around a weeks time. Better than expected! Thank You MFG for the great quality.

What a great service! I am located in Edmonton, AB, Canada and currently growing orchids under fluorescent grow lights and wanted to switch to LED lights for economy. So I did some research. I came across some of the videos of Active Grow LLC and I got in touch with them by email to request information about their lighting system. Not only they provided the information I needed in a timely manner, they educated me about what type of lights will make my orchids flower. After few emails with the owner going back and forth asking questions and the information I needed to make a decision I purchased the lights. Unfortunately, when I gave them my address for delivery I have a typo in my address, which I realized just after the package was sent I contacted the owner and he quickly contacted the postal office to have the correction done. I got my lights a few days after!! What a great service! I really wanted to write this review to congratulate the owner Taylor for the EXCELLENTE CUSTOMER SERVICE I received from him. Professional, timely, informative and always courteous... and did I forgot to say I got my lights at a very decent price... Yup! Great price! Thank you!

Bright, light, and no flicker. I have a small three tier grow stand I use in the winter to start seeds that uses T12 lamps. I've been considering LED replacement for some time and wanted to remove the ballast for weight and heat reasons. I decided to do one 4 lamp fixture first, see how that went, and go from there. I opted for these lamps for a number of reasons, designed with an output for plants, direct wire, dual ends, uses T8/T12 tombstones, and a lumen output higher than others.

My fixtures are made for growing things. Everything is bolted down, not press fit. Some tombstones are riveted in place, some not. It also has an off/on switch and power out. Fortunately the fixture uses non-shunted tombstones so ones riveted in place worked out. I do not have test equipment to measure the exact output. To eye the light appears as bright as the lamps they replaced. There is less heat from both lamp and fixture. With ballast removed the fixtures are easier to move up and down. Time will be the real test. If these last like they should these are well worth time and cost.

These were packed so well that you could have dropped them off the roof and not hurt them. Absolutely the best packaging I've ever seen for a light! 110%.

Good Product. I purchased a full spectrum and a red/blue spectrum light to use in my greenhouse. Both lights were just what I wanted and are working well. Plants are very happy.

Great output. I was happy to find a retro fit bulb to upgrade my old light fixtures. I haven't had the chance to grow much so far but the light is bright, looks nice and has a very good natural white look to it.
