CT-800 800w LED GROW LIGHT FEATURES & BENEFITS


The LED grow light draws 800 watts, producing 2240 umol/s of light and unbeatable 2.8 umol/j efficiency spread evenly across a 4'x4' / 5X5' grow tent.

It is fully dimmable. There is a dimming knob on the fixture; the intensity can be dimmed from 40%, 60%, and 80% to 100%.  Growers can also adjust the metal string to get the proper lighting that your plants require.

The driver is an internal setup in the middle of the fixture. Our engineers keep a perfect distance between the driver and the light bars to reduce the total heat load.  We have conducted comprehensive tests on the fixture's temperature to obtain the best cooling effect. 

We provide a 5-year standard warranty for all the lights, and our customer service team will respond in 24 hours to any inquiries you have.

800w LED GROW LIGHT PAR PERFORMANCE

CT-800 provides consistent and uniform light intensity across the plant canopy and contributes to better growth and development.


800w LED GROW LIGHT TARGET FULL SPECTRUM

We enhance the CT-720 spectrum and formulate the CT-800 spectrum, integrating an addition of 730nm. This new design aims to boost the amount of crop and make the plants bigger. It's made particularly for growing plants indoors and can be used during all the stages of the plant's life. It lets plants take in the light waves they need, when they need them.






HOW HIGH SHOULD YOU HANG CT-800 LED GROW LIGHT


 

800w LED GROW LIGHT DAISY CHAIN CONTROL 

Growers can control up to 100 fixtures using a lighting controller simultaneously without reducing lighting system efficacy. Such a connection is perfect for large-scale commercial production.


800w LED GROW LIGHT FLAT DESIGN

A groundbreaking design that sets it apart from the competition. Unlike other LED grow lights that house LEDs inside the light bars, our advanced CT-800 places the LEDs on the backside of each light bar. This distinctive design allows users to open and hang the light reversely, ensuring a perfectly flat and eliminating the common issue of drooping found in other grow lights on the market.

By opening and hanging the light like a book, this unique design allows for more even light distribution and greater overall efficiency, optimizing the growth potential of your plants.

Good option
Color: White, Size: Body(Pack of 1)
I’ve been using the ACCURATEX Full Body Pillow for Adults – Hybrid Shredded Memory Foam for a few weeks now, and overall I’m really happy with it. The blend of shredded memory foam gives it a firm, supportive feel, but what I love most is that you can adjust the filling to get the exact firmness you want. Whether you prefer something more structured or slightly softer, it’s easy to customize by adding or removing foam. Comfort-wise, it’s definitely a step up from standard body pillows. It keeps its shape throughout the night and offers great support for side sleeping. That said, it is a bit firmer out of the box than I expected, which is why I’m giving it 4 stars instead of 5. If you’re looking for a body pillow that won’t go flat and lets you tweak the feel to your liking, this one is a solid choice.

Favorite pillow!!
Color: White, Size: Body(Pack of 1)
I honestly wasn’t expecting to love this pillow as much as I do. Buying pillows online always feels risky because you can’t actually feel them beforehand, but this ended up being one of the best blind buys I’ve made on Amazon. The quality is genuinely shocking for the price. It feels way more expensive than it is. It’s insanely comfortable, supportive without feeling stiff, and just has that “perfect” cozy feel. I have neck problems, so I’m really picky about pillows, and this one somehow manages to be the perfect balance. It’s supportive without being stiff or overstuffed, but also not too flat where your neck feels unsupported. It has that perfect “sink in but still supportive” feel that’s hard to find. I loved the body pillow version so much that less than a week later I’m already ordering the regular pillow version too. Easily 5 stars from me!!

Probably going to replace all the pillows in the house with these
Color: White, Size: King (Pack of 2)
These pillows are just about perfect. They have to be the best pillow for the money out there at least. I didn't even know that this kind of pillow existed but was asking Google Gemini what kind of pillow would best suit my list of needs and this is what we came up with. - High loft for comfortable side sleeping, but can be reduced by removing foam to be less high - Gives initially, but stays at that new same thickness throughout the night b/c it's memory foam chunks - Doesn't feel lumpy because it has the 1cm outer pillow layer that covers the memory foam pieces I'm 6/3" 210lbs and after a couple nights of adjusting I found that removing about 1 gallon ziploc of foam chunks from each pillow was about perfect. I saved the foam in ziplocs in case I change my mind. They come REALLY loaded at first so should fit literally anyone with some adjusting. It was definitely too big the first two nights until I got it just right.

Hard As Rock When Cold
Color: White, Size: Standard (Pack of 2)
These are good pillows except they get hard as a rock when the temps go below 65F and take 10-20 minutes to warm up at bedtime. Not ideal where the winters are colder or for someone with cervical spine issues.

LUXURIOUS, just like it says
Color: White, Size: Queen (Pack of 2)
I used My Pillows for years which needed constant fluffing throughout the night until they just became useless. Since they became useless, I would always wake in the middle of the night with terrible headaches and my head would be sore all over, throbbing like a boil. I couldn’t stand anything to touch my any part of my head while these headaches occurred. One night almost a week ago I was awake in pain and couldn’t sleep. I started googling for a solution, a pillow that would support a human head, basically a bowling ball. After several products which kept sending me to Amazon, I stumbled upon this pillow. I read all of the reviews. Many compared it to a “luxurious hotel pillow”. So I waited and got them within less than 48 hours. It was a thin box so I wasn’t expecting much. They were vacuum sealed, I opened them and allowed about an hour for them to fully expand. They were comprised of memory foam and down alternative like “luxurious hotel pillows”. They were heavy too. I tried to fluff it for maximum feel. It was extremely firm and I wasn’t able to actually fluff or reform it in any manner really. I could feel the down alternative filling surrounding this semi hard center ( the memory foam I guess) and I fluffed as much as possible. I had difficulty getting it into my pillow case, which was fine to me. It just made me anticipate this perfect looking pillow. I had been suffering with these headaches due to inferior pillows, I couldn’t wait. I laid down and put my bowling ball head on it! It completely supported my head. I normally like my pillow to conform around my neck and shoulders to allow a straight alignment with my head. My head was slightly up, but hey this felt great!!! I could feel the down alternative filler cushioning my head with the firm memory foam in the middle. I could not wait to try it that night. Night comes and I’m excited to see if I can sleep through the night finally without waking with those terrible headaches. I slept almost all through the night except for going to the bathroom once!! And my head wasn’t hurting nor did it feel like a boil!! I was ecstatic to say the least. I know there are people just like me searching for relief. If you can tolerate a firm pillow you can’t go wrong with these pillows. You get two for a great price! I just wish I hadn’t wasted hundreds on My Pillows for all my bedrooms a few months ago. I will be replacing all the pillows in my home with these WONDERFUL pillows!!!
