LAMP ADAPTER E27-GZ10/GZ10
Expect professional grade performance from our HID metal halide lamps. Ideal in retail, commercial and residential applications, metal halide HID bulbs have a long life and produce a crisp white light perfect for areas where color rendering is critical. From standard metal halide bulbs to PAR shape pulse start MH lamps, our comprehensive product selection is sure to impress. Our HID metal halide lineup includes: • Standard lamps • Pulse start bulbs • Ceramic lamps • Teflon coated bulbs • Double ended lamps the manufacturer’s/lamp’s name; the lamp’s nominal wattage; the type of method used to mount the lamp, along with the number of ends in the sockets used to mount the lamps and; the lamp’s color temperature. Metal halide lamps have two basic configurations; those with an outer envelope and those without. In the former, the lamp’s basic construction is an inner envelope (called the arc tube), which contains the arc, and an outer envelope (called the bulb) which filters out ultraviolet radiation (UVR) and shields the inner arc tube. These lamps are typically single-ended (SE) and use a threaded mount to screw into a lamp socket. The second lamp configuration lacks the outer envelope and typically has two ends (double-ended, DE) that need to be inserted into a lamp socket, as we shall discuss shortly. The metal halide ballast provides the proper starting voltage, operating voltage and current to the lamp to initiate and sustain the arc. HID lamps have a negative resistance characteristic, which causes them to draw an increasing amount of current, hence need a current limiting device. The ballast provides these functions. There are several different ballast types used for for HID lighting. Basically, there are two primary distinctions between ballasts: "lag circuit" and "lead circuit" ballasts. The current in lag type ballasts is controlled by an inductive resistance in series with the lamp, whereas in lead type ballasts it current control is provided by both inductive and capacitive resistances in series with the lamp.
