CT-800 LED Grow Light Product Description

CT-800 allows you to create the ideal professional horticulture lighting environment with significant energy savings.

This new multi-bar configuration gives you the ability to mount this LED in rooms with low ceilings, on vertical growing racks, on overgrow benches, and especially in grow tents. The bars are removable and replaceable if any one of them gets defective by accident. They can be mounted to a central driver case. Each bar has a mounting bracket in the center which is easily inserted into brackets mounted on the driver case.

Designed using sustainable energy consumption practices in mind, the CT-800 uses 800 watts and generates little to no heat negating the need for additional cooling or ducting. This fixture features high-power white LED diodes with 4000K and 660nm deep red diodes. This is a perfect blend to produce a wideband spectrum for all phases of growth that penetrates deeply below the canopy, which helps to improve higher-quality flowers and a superior yield.

Horticultural LED grow lights like CT-800 are appropriate for growers who own enough grow spaces and require light quality and intensity. Operating at only 800 watts with an output of 2160 µmol/s, this LED achieves an elite photon efficiency of 2.7 µmol/J at 277 AC.

The CT-800 covers 5 by 5 feet during flowering and 6 by 6 feet during vegging. It delivers ultra-high PPFD, up to 1600 µmol/m2 in 5 by 5 grow space, to take advantage of supplemental CO2. Growers without supplemental CO2 can get excellent results with the Cultiuana CT-800 at 80% power. For the ideal uniformity, hang light 6” – 10” above crops for a bountiful return on investment.

The fixture has an onboard knob for dimming between a range of 320 - 800 Watts. To be specific, you are able to turn the knob to 40%,60%,80%, and 100% to get different lighting as per your plant's needs. There is a setting on the knob to turn to EXT for the external controller. With a single Cultiuana lighting controller, you have full control of up to 100 pcs of fixtures.   

Looking to grow full-cycle from the comfort of your own home? Our CT-800 LED grow light requires no maintenance, no bulb changes, and no worrying.

enough for 5x5

So far, I've seen a huge increase in the leaves grown since using this product. It provides more than enough light coverage for my 5x5 in veg.
