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

Decent quality for the price
Color: Grey
Decent quality for the price. Other privacy screens were extremely out of my budget, but this looks and works just fine- I just needed something simple to place behind my couch to hide some clutter. It took me about a half hour to assemble, but it was easy enough. It might be due to my carpeting, but I don't trust that the screen would be stable enough to stand freely without falling. Thankfully my plan all along was to wedge the screen between the couch and a box of clutter anyway, so for me it works as l'd planned!

Overpriced but effective.
Color: Cream
I happened to get lucky and get a warehouse deal at an additional 30% discount. Even at $25, it feels a little overpriced. But it was easy to assemble and serves its purpose. If you line the Velcro up exactly, the panels sag, if you stretch past even, but where it still grips, they look pretty ok. It is very light and does fold very compact for easy storage.

Great price for a great product
Color: Coal Black
Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

No.
Color: Coal Black, Color: Coal Black
This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

You have to add weight to it
Color: Coal Black
It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy
