The 4 Foot Cone Grow Light System includes a bulb, ballast, reflector and socket assembly. The 4 Foot Cone systems spread the light out over a wide area. The sides are flat not curved like the parabolic systems. This reflector does create a bit of a hot spot directly under the bulb. The bulb is mounted vertically in the center and can be adjusted up and down. Choose your ballast below. The power cord is 8 feet and the lamp cord is 15 feet.
The Sun System 10 Ballasts are the low cost option for the grower on a budget. They operate the same as other ballast with the same efficiency. They have rubber feet to reduce vibration noise.

The Sun System Switchable Ballasts can run halide or sodium bulbs just by flipping a switch. The 1000 watt systems use a standard 1000 sodium ballast and the switch disconnects the ignitor. For the 400 watt systems, a special ballast is required because the voltage difference between the halide and sodium is too large. The open circuit voltage for the standard halide 1000 is 430 volts and 435 volts for a sodium 1000. A standard halide 400 has an open circuit voltage of 300 volts but the sodium 400 is only 190 volts. So the 400 watt switchable systems switch the ignitor and change the lamp tap on the transformer too.
