A few days ago, I bought an ordinary 70W high voltage sodium lamp bulb with an ordinary light interface. It seems to be ED, but I don't know if it is the same as the regular incandescent lamp Still have to be modified? Thank you！！！ What does "ED" mean?
Metal halide lamp (Metal Halide Lamp) is the AC power supply, arc discharge luminous lamp in halide mixed vapor mercury and rare metal, metal halide lamp is made to add a variety of metal halide light source in the third generation based on high pressure mercury lamp. Sodium scandium metal halide lamp by lighting the lamp, has the characteristics of high luminous efficiency, good color, long life performance significantly, is a new energy-saving light source close to daylight, widely used in the stadium, exhibition center, large shopping malls, industrial buildings, street square, station, wharf and other places of indoor lighting.
Metal halide lamps and high pressure sodium lamps can be used indoors, but single - plus rectifiers are required. High pressure sodium lamp is a kind of high intensity gas discharge bulb. Due to the negative resistance characteristics of gas discharge lamp, if the bulb alone received the power grid, the working state is unstable, with the discharge process continues, it will lead to the current in the circuit infinite rise, parts and components of last lights or the circuit is overcurrent burned.
When the high voltage sodium lamp is used, the golden colored light is generated, and the utility model has the advantages of high luminous efficiency, low power consumption, long service life, strong fog resistance, no corrosion prevention, etc.. Widely used in roads, highways, airports, docks, docks, stations, plazas, street junctions, industrial and mining enterprises, parks, courtyards, lighting and plant cultivation. High color high pressure sodium lamp is mainly used in stadiums, exhibition halls, casinos, department stores and hotels and other places lighting.
Indoors, but ballast must be usedBut from your description, the ED model should be a metal halide lamp, also called a single ended metal halide lamp, not a sodium lampThe temperature is a bit high, but it's not a big problem. Many Arcades Hotel are now being used indoorsED and BT refer to the shape of the bulb housing
