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 metal halide ballast to operate. Traditionally, magnetic ballast 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.There are four basic components in any MH lighting system (not including the mounting hardware and wiring):
After the specific lamp has been selected, the next step is to check the lamp’s mounting lamp holder. The lamps most commonly used in the hobby are single-ended, with a screw-type mounting lamp holder. The size of the lamp holder and the threads is also described by a code, although names are more commonly used. For example, lamp holder - E39 is commonly called a mogul lamp holder. European lamps also have a mogul lamp holder, but it is slightly different from the E-39 and is called E40. The differences are small enough that the E40 lamp holder lamps will work fine in the typical E39 mogul lamp holder used in the U.S. Double-ended 150-watt lamps use the RSC (RX7s) lamp holder, while the 250-watt double-ended lamps use the Fc2 lamp holder. Figure 3 shows the various shapes and configurations of lamps and lamp holders, along with the restrictions on their various operating positions
