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.

Nice little jewelry box
Color: Cloud White, Material Type: Paper, PU
Just what I wanted in size and available compartments. The only thing I am hesitant about is the paper outside. Mine is white and may get dirty quickly.

Great value, great product!
I use this as a home jewelry box - I don't wear a lot of jewelry, so it fits my needs perfectly. Its pretty lightweight and would be good for travels as well. The outside is leather-like and seems to be waterproof so far. I use the first layer for jewelery and second layer to store my hairclips and pins. I've had it for a few months and it seems to be great quality and durable! Definitely a good value as well because I've seen similar jewelry boxes sold at popular retail stores for over $30.

Lovely Slate Gray Jewelry Box
I just received this Slate Gray jewelry box. It's really quite lovely and just the right size for my granddaughter's vanity. I'm really excited about giving it to her, for her 12th Birthday, to hold her better jewelry. It's so nice I'm going to order another one for my other Granddaughter's Birthday.
