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. 


800w LED GROW LIGHT ACCESSORIES

  • 1 x AC Power Cord (6 ft / 1.8m)
  • 1 x RJ 14 Wire 
  • 2 x Ratchet Ropes
  • 1 x US adaptor
  • 2 x Hooks


Rest assured, we stand behind CT-800.

When you buy a light fixture from Cultiuana, you purchase more than a grow light. You're buying the peace of mind that comes with knowing we stand behind our products with our hassle-free replacement guarantee and lifetime technical support.

An Essential (Unique) Resource
I have been in finance for nearly thirty years, but accounting for my hobby writing practice is still a mess. Lots of laws, and rules, and detail. Yuck – who has time? Christy’s book simplifies many of these issues, distilling them down to the essentials, and empowering writers to do much of their own financial work. It may not eliminate the need for an accounting professional, but enables and may reduce those costs (not to mention – your accountant will appreciate you being more organized). This included everything from legal structure, to accounting and taxes. The exercises are relevant and not overwhelming. Great resource for anyone with a writing practice, whether it be international bestseller or those of us building on our hobby.

Great resource for authors
Format: Kindle
The book offers a variety of helpful tips from running your own business, filing types, inventory, taxes, and more. I will be referencing it again as it has so much information that I need to look back on. I received an advance review copy for free, and I am leaving this review voluntarily. Two issues with the book: 1) Parts of the book sounded like AI. Words like crucial, labyrinth, and the extensive use of bullets left me somewhat suspicious. It’s not a huge deal as it was heavily edited but was noticeable. 2) Formatting of some parts were in all bold which was hard to read. Entire bulleted sections were all bolder instead of just the first sentence. It needed to be updated and I think this was missed. The book is helpful and a good resource despite these two issues. I appreciated the vast amount of information provided which will be beneficial in the future.

Love the bottle warmer like that it rotates very affordable . Used with water has keeping warm capability and has a tiny night light wish it was bigger . Can be used for traveling since compact and don’t want to buy a portable one . Just dump water very durability seems like it’ll last you a while but having it for a few months now . Cord I will say a bit short

Great!
This is a great bottle warmer with multiple options for heating. It works great and heats a 4 oz. bottle on the "quick" setting in a little over 3 minutes depending on how warm you desire the milk to be. The gentle spinning action keeps any portion of the milk from overheating. I am very happy with this product.
