400 Watt Sodium/Halide Switchable Cool Sun Grow Light System

400 Watt Sodium/Halide Switchable Cool Sun Grow Light System


The Cool Sun Grow Light System includes a bulb, ballast and reflector. The Cool Sun Reflector is a large reflector with 6 inch ducts on each side for pumping air through to cool the system. The 6 inch ducting and wide open flow is a much more efficient system than the old 4 inch systems. The inner surface is lined with 95% reflective aluminum with a dimpled finish for maximum uniformity and light output. The outer surface is powder coated steel. The socket is built into the reflector and has a 15 foot lamp cord. The reflector measures 24 x 20-1/2 x 7-1/2 inches. Glass is included at no extra charge. Air cooling your lights will increase plant growth because of lower temperatures in the grow room. The lamps will last longer running at lower temperatures too. An air cooled system is better for rooms with carbon dioxide (CO2) enrichment because most of the air flow for cooling can be separate from the environment of the plants. Includes "V" hooks for hanging.

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.

  • 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.
