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.

Do away with vet teeth cleaning. Great product.
Color: Monster Bone, Size: XX-Large
My large dogs love these. It keeps their teeth clean and no tarter or cavities after 4 years of using. It has even helped an adopted older dog to have stronger teeth. They don't ingest anything, so safe to chew on.

Great for chewers
Color: Knuckle Bone, Size: XX-Large
I have a 13 month old 56 lb boxer/rottie mix who is a medium chewer and this bone is great for him. No splintering, doesn't make a mess, and hard enough to make him work without any danger of him breaking teeth, getting cut, or choking. We gave it to him a couple of weeks ago and based on wear I'm confident it will last him a long time (many months at least). I was a little hesitant about giving my animal a product that contained nylon, but after a scary experience giving a rawhide bone to a previous foster dog, I was told this was a much safer option and now I agree. This bone is very dense and very hard, so it makes an awful noise when my dog drops it on my hardwood floor. We are also careful to make sure he doesn't drop it on our bare toes, because that would be quite unpleasant. Be aware that the chewed edges also get really rough because of the way the bone wears, so they can become a magnet for dog hairs or fabric threads. This hasn't been a problem for us (we just encourage our pup to chew it on his bed and take it away from him when we are watching a movie so the noise isn't bothersome), but it is good to know. Update: We've had Winston for 5 months now and in that time he has gained 5 lbs of muscle. He loves his Nylabone! It is still going strong and I think he will be able to use this well through his one year adoptiversary. The only issue we have with this bone is that the edges can get sharp and sometimes will cut his mouth. He doesn't notice and just wants to keep chewing, but we usually take the bone away at that point for a bit. My boyfriend has taken the bone and used a power sander on it a few times now to remove all the sharp edges. We only have to to in once every couple of months but it makes a big difference.

The best toy my dog has
Color: Monster Bone, Size: XX-Large
Our lab mix is a very ambitious chewer - forget retrieving... he seems to think his "job" in life is to destroy things with his teeth. He's very methodical about it; he'll chew and chew and chew, targeting the object's weakest points, until all that remains is a littering of coin-sized remnants. He even started to make progress on his heavy duty black Kong within about a week. By the time he was about 8 months old, we figured out that the only toys he can be left alone with are the ones made by Nylabone. He has all their models: dinosaurs, rings, small bones, and branches. These Nylabone toys are a hard plastic that chips off in tiny little shards. He's happy because he feels like he's making progress (even though it takes him a long time to do so) and we're happy because the toys last a relatively long time and he can't swallow anything that might hurt him. He does leave tiny plastic shavings on the carpet, but we have to vacuum a lot anyways because of his fur, so it's not a big deal. Of all his Nylabone toys, this is the best (and probably his favorite of the bunch). He really likes the size - just right for him to prance around with and show off. Although he's had it for four months, it's still smooth enough in the middle that we can hold it for him comfortably, and it's retained its original shape (unlike dinosaur and branch). If we could just train him not to drop this on our feet when he wants attention(it weighs a few pounds and has gotten a bit pokey on the ends)this would be the perfect toy.
