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.

Fresh and Flavorful Pepper
Size: 16 Ounce (Pack of 1), Size: 16 Ounce (Pack of 1)
These Sauer’s whole black peppercorns are very fresh, strong, and full of flavor. I love adding them whole to meats and rice, for me it’s always a nice surprise to find a peppercorn in a spoonful and taste that magical, spicy kick. The quality is excellent, and the aroma is natural and bold. The 1 pound canister is a great value because it brings a lot and lasts a long time. Perfect for grinding or using whole in everyday cooking.

Fresh, Bold Flavor That Transforms Every Dish – A Kitchen Staple Worth Stocking Up On!
Size: 16 Ounce (Pack of 1)
As someone who cooks for a family of six and hosts weekly dinners, I needed a reliable source of high-quality black pepper that wouldn't lose its punch in bulk. Sauer's Whole Black Pepper in this 1-pound canister has been an absolute game-changer. The peppercorns arrived perfectly fresh, with that deep, aromatic aroma that hits you the moment you open the lid – no stale or dusty vibes here. They're uniform in size, easy to grind (whether in a mill or mortar), and deliver a sharp, spicy kick that elevates everything from simple scrambled eggs to my signature grilled steaks. The canister itself is a smart design for foodservice pros like me – airtight seal keeps moisture and air out, so it stays potent for months without clumping. I've already gone through half in just three weeks of heavy use, and it's held up flawlessly. No fillers, just pure, whole black pepper from a brand I trust. If you're tired of pre-ground stuff that tastes like sawdust, grab this – your taste buds will thank you. Five stars all the way; I'll be ordering the next canister before this one runs dry!

Nice Peppercorns
Size: 16 Ounce (Pack of 1), Size: 16 Ounce (Pack of 1)
Very pleased with these Sauer’s whole black peppercorns. The quality is excellent — fresh, aromatic, and full of flavor. They grind easily in my pepper mill and make a noticeable difference compared to pre-ground pepper. I’ve used them on everything from salads to steaks and soups, and the flavor really stands out. Great value for the amount you get, and I’ll definitely purchase again
