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.

 

 

800w LED GROW LIGHT DIMENSION



CT-800 is an 800-watt LED grow light designed for home and commercial growers. The dimension is 42.5x45 inches when folded out to its final form; you can expect the fixture to distribute the light evenly in a 5x5 area for the vegetative stage and a 4'x4' for flowering.

  • 1 x AC Power Cord (6 ft / 1.8m)
  • 1 x RJ 14 Wire 
  • 2 x Ratchet Ropes
  • 1 x US adaptor

Rest assured, we stand behind CT-800.

When you buy a light fixture from Cultiuana, you purchase more than a grow light. You're buying the peace of mind that comes with knowing we stand behind our products with our hassle-free replacement guarantee and lifetime technical support.

Fun new toys
Color: Yellow & Grey & Brown
My dog loves him. They’re easy to squeak and carry in his mouth so it’s a bonus bonus for him. He’s a puppy so he’s not the most coordinated thing yet.

Cute and Durable
Color: Them Apples, Color: Them Apples
I have purchased several Barkbox brand toys for my dog. “Them Apples” may be the cutest of them all. I am impressed at how well-made and designed this toy is. There is a large squeaker at the base of the tree and the rest of the tree has crinkle sound. My dog enjoys playing with the tree as much as he does playing with the apples. The apples are also well made and not flimsy like so many other hide & seek toys. The apples also have squeakers in them. My dog has had this toy for a couple of months now, and it’s still in good shape. I will definitely repurchase if this one ever wears out. Good value for the price.

Super cute and my dog is obsessed!
Color: Donuts, Color: Donuts
This is my crazy lil rascals first toy! She loves her donuts so much, they are pretty sturdy, she did manage to chew a corner off the box but that's expected. She loves the crinkles and taking everything out! My only problem is that it is a bit hard to close with the donuts in there, luckily she always loses one under the couch anyways 🤣 They are super easy to just carry in a purse if you are taking your dog with you and easily washable in the washing machine! The material is super soft and crinkly and all of the donuts have different textures along with squeakers! It is a bit small, so I attached a photo! I got her another one that is bigger recently, it's animal crackers and she is OBSESSED 100/10, always choosing bark for my pups
