The AB Lighting Horti-Tube 28W is essentially a clone light designed to grow seedlings, clones, or herbs. High blue light content.

These transparent four-foot-long tubes are daisy-chainable (up to 10 fixtures) on one single power source. Because these emit virtually no heat they can be hung directly over the crop.

The Horti-Tube 28 watt boasts an impressive 2.3 µmols/J efficacy. These fixtures operate on 120V or 240V power.
