The (2 Pack) of Agrobrite 48W 2-Foot 2-Tube Fluorescent Light Fixtures with Bulbs is one of the new Designer T5 Systems that delivers performance, flexibility and high lumen output in any indoor growing environment and with a variety of plants. These daisy-chainable systems allow you to choose multiple hanging configurations to meet your indoor garden’s design. They combine German specular aluminum with energy-efficient/high-output T5 bulbs and put out double the light energy of normal fluorescent systems, while emitting limited heat, ensuring tender plants don’t get damaged. The Agrobrite T5 light system has a powder-coated textured steel housing and comes with an 8-foot grounded power cord. T5 light systems are especially well-suited to growing vegetables, cloning or seedlings. These units can be hung either overhead or vertically for maximum versatility.
