JAMES carried out the American standard ballasts verification and authorized the verification mark that will be affixed to the American standard ballasts，High Pressure Sodium and Pulse-Start Metal Halide Lamps High pressure sodium and modern metal halide lamps which include existing lamps, 150W and less, as well as the new generation of pulse-start metal halide lamps, 150W and greater, have no starting electrodes.
In addition to an OCV of approximately two times the lamp voltage, these lamps utilize an “ignitor”to provide a high voltage starting pulse directly across the main electrodes. Once the lamp’s arc is established,the ignitor automatically stops delivering pulses, and the lamp comes up to full brightness on its own.
High pressure mercury bulb, also called high pressure mercury lamp, a gas discharge light source. It has the advantages of high light efficiency, long life and good shockproof performance; but there are also color discrimination rate is low,supply voltage decreased by 5% there will be self extinguishing and closed for 5 to 10 minutes in the bulb mercury vapor pressure drop to re ignite and other shortcomings.
When using high pressure mercury ballast, should pay attention to the following matters:
High pressure mercury lamp power in 125w and the following should be matched with the porcelain E27 lamp holder; power in 175W and above should equipped with E40 porcelain lamp holder.
with which type of HID lamp the product is designed to operate;
number of HID lamps the American standard ballasts is designed to operate;
for which of the following ballast input voltages the product is designed:
High-intensity discharge American standard ballasts (HID) for metal halide lamps are now offered for many lamps up to 150 watts. Magnetic ballasts should strengthen lamp efficiency and present a restricted variety to achieve some energy savings, A light fixture is actually a unit consisting of 1 or much more on the following elements:
bulbs and light bulb socket
high-intensity discharge ballasts
lenses, refractors, louvers, blades, or other shielding.
An efficient luminaire optimizes the program efficiency of every of its components. There are a few forms of luminaires that provide possibilities for power conservation in a lighting system design. Many of those supply indirect light to brighten the ceiling or are developed to brighten walls or process surfaces. Most of them are fluorescent and are conveniently controlled for further power savings.
