Advancements in LED technology have created a real boon for indoor growers.
Although these fixtures consume less energy than fluorescent tubes of comparable size, they produce more light and less heat, emitting full-spectrum light that closely matches the wavelengths of natural sunlight.
With a color temperature of 6400 kelvin, they promote vigorous growth, each illuminating an area as long as the fixture and about 24" wide when placed at a height of about 1'. To increase coverage or intensity, you can link multiple lights (up to five of the 12" fixture, ten of the 24" or eight of the 48") from a single power cord.
Each consists of a high-output LED array set in an aluminum housing with integrated reflectors, and comes with mounting hardware, a 13" coupler cord and a 66" power cord. They operate on 12W, 24W and 48W respectively. Rated for 50,000 hours of continuous operation.
The lights can also be used as replacement fixtures on grow-light stands using the included clips and hardware.
