CT-660 LED Grow Light Product Description:

Be confident that you will increase your yields and crop quality with this super bright LED grow light, CT-660! CT-660 is a full spectrum LED grow light meant to provide enough uniform light for a 4’ x 4’ grow space. It features quality components and has some features that make it stands out in the market.

The CT-660 draws true 660 watts from the plug. It is supposed to have an equivalent light output of a 1000-watt HID bulb. The PPF is rated at 1716 μmol/s with almost every photon absorbed by the plant, and efficacy at 2.6 umol/J.

CT-660 uses the quality white diodes designed by Cultiuana which cover a wide spectrum of PAR and produce more intense light with fewer watts. It also incorporates the most efficient Osram 660nm diodes that create an ideal spectrum for vegetative and flowering stages.

However, strong and efficient light isn't the only thing Cultiuana is going for. We know uniform coverage is what every grower cares about most when shopping for an LED grow light. To achieve this, our engineers used 8 bars with a foldable design to spread the light evenly over your canopy, including the lowest parts, and algorithmically placed diodes to create a great uniformity of coverage. So with a single light, it's easy to cover all angles of your grow area evenly.

When you check the PPFD chart, you'll see that in a 4×4 growing surface area, the average PPFD reading is 1138 μmol/m2 from a height of 12 inches. It stays consistent in literally every part of the surface area, even when hanging at a low height, it ensures the contribution to the edges and corners.

The onboard dimming knob is accurate in the PAR ranges. It has preset options for 40%, 60%, 80%, 100%, and external control. So by dimming up or down the light, you can fully control the efficiency at any given time.

Have a larger growth? No problem, as 50 lights can be connected through the daisy chain ports and controlled by a single dimmer or controller.

The CT-660 truly doesn't get hotter than the stated maximum operating temperature of 113°F/45°C. The passive cooling mechanism is designed very effectively with heatsinks, so you probably won't need any active fan to cool down the light.

This fixture is DLC listed and we always stand behind our lights. We offer a 7/24 online service, a 3-year limited warranty, which is about the industry average, and a free return for an exchange/replacement.

Super great fixture!

The Cultiuanna has been really great, I'm super happy with how easy it is to manage the heat and the light spread is really even. I'm hoping we'll see some good penetration into the canopy as well with so much power.

light is up

She lights up pretty nice.
Dimmer settings are 20%-40-60-80-100-off-ext
I’m assuming the ext place on the dial is used when daisy chaining multiple lights together. We won’t be utilizing that feature, so that saves me that dilemma.
