China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

High-intensity discharge (HID) lighting systems are widely used in applications where high light levels are desired for large areas, such as industrial and street lighting. Similar to fluorescent lighting systems, all HID lighting systems require a ballast to operate. Traditionally, magnetic ballasts designs were the only choice available for HID lighting systems. Today, high-efficiency electronic HID ballasts are available that provide improved lighting quality and reduce lighting electricity use by 10 to 30 percent.¹ The dimming capabilities of some models can provide additional savings. That's good for your company, and it's good for the environment. Reduced electricity use provides cost savings, and it reduces greenhouse gas emissions associated with electricity generation that contribute to climate change.

STANDARD IGNITORS
Standard Ignitors are supplied with all Universal High Pressure Sodium and Metal Halide ballasts requiring ignitors.
These ballasts are supplied with an appropriate external ignitor unless the ignitor is permanently attached to or built into the ballast.
INSTANT RESTRIKE IGNITORS
An Instant Restrike Ignitor generates multiple pulses to restrike a lamp arc after a brief power interruption has extinguished
it, without the typical 3-minute cool-down time. A Standard Ignitor cannot restrike an arc until the lamp has had time to
sufficiently cool. Even though an Instant Restrike Ignitor can reinitiate the lamp arc immediately upon restoration of power,
the lamp is still subject to warmup. The following chart is based

HID ballast use magnetic coils to regulate current and voltage to provide proper lamp starting and operation. These magnetic ballast tend to be hot, bulky and heavy, which affects their suitability for some applications.

LONG DISTANCE IGNITORS
Long Distance Ignitors are used in situations where a ignitor must be mounted further from the lamp than is recommended
for a standard ignitor. The maximum lamp to ignitor distance for these ignitors is 50 feet, which may vary depending on the type
of lamp, ballast, fixture, and wiring.
