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

Get another chain
Color: K
The charm isn't bad. However, the chain broke in the first two hours of my wife wearing it.

Classic Initial Necklace with Ageless Style
Color: T, Color: T
I bought the DORANA Initial Necklace because I wanted a simple, elegant piece to complement my V‑neck and cowl‑neck tops. I rarely wear necklaces, but this one adds just enough polish without feeling flashy. The chain is thin, lightweight, and has a nice 18k gold finish that feels more like real jewelry than costume. Even though the initial-and-heart design leans youthful, it still looks refined on a mature woman and adds a subtle, modern touch. The 16‑inch chain fit like a choker at first, but the 2‑inch extender let me adjust it to the perfect length. My only concern is how well the polished finish will hold up over time. Overall, it’s a simple, budget‑friendly necklace that works for teens through grown women and pairs easily with casual or dressy tops.

Super Cute and Dainty—Perfect for Gifting!
I ordered this dainty pink heart initial necklace as a birthday gift, and it is honestly so adorable in person. The pink heart has a really nice, vibrant color, and the gold finish looks super trendy and clean. It’s the perfect length (16 inches with a 2-inch extender), so it sits right on the collarbone and layers really well with other gold chains. It makes for a really sweet, personalized gift for a mom, friend, or even a preteen girl who loves that "soft girl" aesthetic. The initial letter is subtle but clear, and it doesn't feel overly heavy around your neck. Why I'm giving it 4 stars instead of 5: The only real downside is that the chain is very thin and delicate. You definitely have to be careful not to yank it, and I wouldn't recommend sleeping in it or wearing it in the shower if you want the gold plating to last. It’s also smaller than it looks in some of the product pictures, so just make sure your expecting something truly miniature and "dainty." Overall, for the price point, it’s an awesome piece of trendy jewelry. It looks much more expensive than it actually is, and the packaging makes it super easy to gift right out of the box.

Pretty initial necklace
Color: A, Color: A
This is a cute necklace that I ordered for my daughter. This necklace is nice because it's decent quality but I wouldn't be devastated if it broke or got lost. The initial is nicely made and the chain is delicate. It's the perfect size for my 7 year old and I think my 11 year old would also like it. When I ordered it, it was $15 but now there is a coupon to make it $12 which is a great value. I would buy it for myself if it was silver. It comes in a nice box that makes it great for gifting.
