These lighting systems come complete with everything you need to grow plants indoors, including the bulb, ballast, reflector, socket assembly, 15' lamp cord, wire hooks for hanging reflector and instructions.  Most ballast assemblies feature multi-tap transformers, which means that you can switch them from 110/120V to 208V, 220/240V or 277V in just minutes by changing one wire, at no additional charge! The 15' heavy duty detachable lamp cord with it's quick-disconnect adapter makes installation a snap. All bulbs come with a 1-year warranty (you will probably want to replace your bulbs once a year for optimal performance anyway, so you're covered!). Most ballasts feature a 5-year warranty.

Gavita makes the perfect horticultural optical system. They engineered the reflector optics and built them right into the lamp. Then they perfectly aligned the arc-tube to maximize lumen output at an astounding 95% efficiency. It's a well-known fact that the closer the arc-tube is to the reflector, the more light will be available to the plants, and you can't get any closer than the Gavita! And, because the reflector is on the inside of the glass, there is no need for assembly, and the reflective material never needs cleaning, so you're assured 100% reflection, 100% of the time. And if you're still not convinced, it has the best engineered lighting footprint in the greenhouse lighting industry, with a spectrum specifically designed for growing plants. What more could you ask for?

The Gavita is also available with a Cool Tube Reflector! Look under the 400W and 600W Cool Tube Grow Light Systems.
