CT-720 LED Grow Light Product Description

CT-720 is a 720-watt LED grow light, it is 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. 

CT-720 uses the big Sanan series chips and famous Osram 660 nanometer deep red diodes. OSRAM is one of the globally leading brands in the light industry. Their LEDs are designed to meet the unique needs of cultivation, including high efficacy, and longevity, low thermal resistance. 

The fixture draws 720 watts and produces 2016 umol/s of light and unbeatable 2.8 umol/j efficiency spread evenly across a 4'x4' grow tent.

The driver is an internal setup, it sits in the middle of the fixture. Our engineers keep a perfect distance between the driver and the light bars in order to reduce the total heat load.  We have conducted comprehensive tests on the fixture's temperature to obtain the best cooling effect.

Growers can control up to 100 fixtures using a lighting controller at the same time without reducing lighting system efficacy. Such a connection is perfect for large-scale commercial production.

CT-720 is fully dimmable. There is a dimming knob on the fixture; the intensity can be dimmed from 40%, 60%, 80% to 100%.  Growers can also adjust the metal string to get the proper lighting that your plants require.

amazing CT720

I've purchased several CT720 and I'm really happy with them. The team is quick to respond to feedback and the shipping is very fast. They've done a great job every time I've used them. The coverage and penetration of the canopy are both great. I recommend this lamp, as well as a few others, to my clients.

Maurice Levvy

I'm thoroughly impressed with this LED grow light! It's very powerful and has made a noticeable difference in the growth of my indoor plants. It's also energy-efficient, which is a huge plus. A great investment for any plant enthusiast!

Worth every penny

These are amazing - I wish I had known about them a year ago! They provide three times the amount of light for a fraction of the cost. I will definitely be sharing with all my friends and when I add another tent to my collection, I'll be purchasing more of these!
