Sodium gas discharge lamps can be distinguished in two main groups: low-pressure sodium lamps in which the gas pressure is very low (0.7 Pa or 7.10 −6 atm) and high-pressure sodium lamps in which the gas pressure is a factor 10,000–100,000 times higher (10–100 kPa); [2–4] cause their construction and performance is in many ways …
Testing capacitors with a multimeter is a fundamental skill in electronics maintenance and repair. Capacitors, vital components in electronic circuits, store and release electrical energy. However, like any electronic component, they can degrade over time or become faulty due to various factors such as age, heat, or overvoltage. In this …
Fig. 1: An example of how a metal halide lamp works based on a double-ended lamp with a quartz arc tube. Similar to high-pressure mercury lamps or high-pres-sure sodium lamps, metal halide lamps also belong to the group of discharge lamps. Low pressure discharge lamps include fluorescent lamps and compact fluores-cent lamps.
High Pressure Sodium (HPS) lights are a type of gas-discharge light commonly used in outdoor lighting applications such as streetlights, parking lot lights, and security lighting. These lights produce a bright yellow-orange light that is highly efficient, making them a popular choice for outdoor lighting.

Once you are sure that you have the suitable connectors in the right place, it''s time to mount the capacitor again. Take the screws you removed previously and install the capacitor using solid pressure. Be careful not to strip the screws when installing. If the capacitor does not use screws to install, it should simply snap into place again.
