Item Details

The 4 Foot Parabolic Grow Light System includes a bulb, ballast, reflector and socket assembly. The Parabolic systems are for spreading the light out over the widest area. This will result in lower light levels but larger coverage. The reflector is just under 4 feet across. The bulb is mounted vertically in the center. This is excellent for large rooms that require the light to be spread out over a large canopy of plants. The socket sold with this system features the adjust-a-socket mechanism which allows you to adjust the depth of the bulb in the reflector to further optimize your light pattern. The 4 foot reflectors are best for the larger lights like the 1000 watt systems. The lamp cord is 15 feet and the power cord is 6 feet long.

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.
