The 1000 Watt High Pressure Sodium Yield Master II Grow Light System includes a bulb, ballast, and reflector. The Yield Master II grow lights have a large (20 x 21 x 7-1/2 inch) reflector. The systems come complete with the standard bulb, Horizontal Reflector and a ballast. The inside of the reflector is fitted with reflective material to help reflect and diffuse the light to create a more even light pattern. The rest of the reflector has a white, powder coated, durable coating. Although this is a big reflector only two of the sides are angled. A reflector like the Sun Gro with four angled sides produces a more even light coverage.

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.

• Die cast aluminum housing
• Louvers for cooling
• Rubber feet
• Multi-volt ballast
• 8 ft. grounded power cord
• White powder coated finish
• Printed UPS shippable carton
• High temperature domestic
• Now with 120 / 240 Volt power selector

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.
