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)

The "Lazy Professional" Look: Is Hands-Free Luxury Actually Real?
Size: 9.5, Color: Black Napa Leather
Living down here in Florida, my footwear needs are pretty specific. It’s hot, it’s humid, and I spent half my life rushing from the car into work or a meeting. I’ve reached that age where I value efficiency just as much as style—maybe more. I’ve been eyeing the Marc Joseph New York Hands-Free Slip-on Penny Loafers for a while, and after putting them through the wringer, here is the honest truth from someone who just wants to look sharp without the hassle. The "Just Step-In" Reality Look, the big selling point here is the "Hands-Free" tech. We’ve all seen the commercials for those athletic slip-ins, but finding that in a legitimate leather penny loafer is a different game. Does it work? Yes, surprisingly well. The heel counter is firm enough that it doesn’t collapse when you slide your foot in, but it doesn’t feel like a piece of plastic digging into your Achilles once you’re in. For those of us who are tired of bending over or hunting for a shoehorn every morning, this is a genuine quality-of-life upgrade. The Florida Factor: Comfort and Style The leather is actual calfskin (on most models), which is a must for the Florida heat. Synthetic shoes turn into a sauna within ten minutes, but these breathe reasonably well. The aesthetic is classic—it’s a "professor" shoe through and through. You can wear them with chinos and a blazer for work or throw them on with some nice jeans for a weekend lunch. Inside, they’ve got a gel heel insert and a padded footbed. It’s not quite "walking on a cloud"—let’s not over-hype it—but it’s a massive step up from the hard, flat soles of traditional dress loafers. I’ve spent four hours on my feet lecturing, and my arches didn’t hate me by the end of the day. The Sizing Gamble Here’s where you need to be careful. The consensus from other guys (and my own experience) is that the sizing is a bit of a coin toss. They tend to run a little large and sometimes wide. If you have narrow feet, you might find the sides "gaping" or flaring out when you walk, which kills the sleek look. I’d recommend ordering a half-size down if you’re usually between sizes. The Breakdown The Pros: True Hands-Free: You can actually put these on while holding a coffee and a briefcase. No hands needed. Legit Materials: The calf leather feels premium and smells like the real deal. Versatility: Perfectly bridges the gap between a "car shoe" and a formal loafer. Comfort: The gel insert makes a noticeable difference for long-duration wear. The Cons: Sizing Inconsistency: They can run wide, leading to some "heel slip" if you don't get the perfect fit. Break-in Period: The heel is stiff by design (to allow for the slip-on feature), so expect a day or two of minor stiffness. Price Point: They aren't cheap, though often on sale. Value for Money Are they worth it? If you’re comparing them to high-end Italian brands that cost $500, these are an absolute steal. They look 90% as good for a fraction of the price. However, if you're used to $60 mall shoes, the jump to $150+ might feel steep until you realize you’re paying for the convenience of never having to touch your shoes to put them on. For a daily driver in a professional setting, the value is definitely there.

Step In Look Good
Size: 11.5, Color: Cognac Napa Leather
I am wearing these shoes as I write this review, and they look and feel great. I have a bit of a disability with drop foot on the right leg and bilateral neuropathy and have been wearing step in shoes for about 10 years. But the first company that introduced leather dress and casual shoes stopped making them and now only makes sport and casual shoes. So I have been searching for some that meet my need for shoes like this and this company has given me three pairs, so far. Easy to get into, comfortable to wear, and good looking. And they take polish very well, too. (Remember how to do that?). We may buy another pair or two in different styles as well.
