The Cirrus LED 1K LED Grow Light is a game changer. It is (along with the much more expensive Black Dog PM-2 1000) the highest yielding LED grow light to date. It produces larger yields than even high wattage DE HPS fixtures.

What really sets it apart is the price. At $999, it is the only high-quality LED grow light available for less than $1 per watt.

The Cirrus 1K achieves this by using full-spectrum driverless COBs, paired with high performance heat exchangers. This cutting-edge design allows for greater cooling, light-output, and efficiency.

The 1K does not save you much on electricity usage over a 1000 watt HID light. But it gives you 50% more output and generates less heat. It also requires no bulb changes and is much easier to install and operate.
