China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Lamp Ballast For High pressure Sodium Lamp,HPS Lamps provide the same long life and outstanding efficiency as standard HPS lamps, with the added benefit of TCLP compliance.  James lamps feature reduced mercury levels and a lead-free base.  This translates into lower disposal costs in addition to lower maintenance costs. In addition, Medium Base HPS Lamps fit standard HPS medium lamp base sockets. No new ballasts or fixtures are needed.

HID Ballast for high pressure sodium lamp and metal halide lamp,70-400w, 220v-240v, 50HZ-60HZ

A lamp needs energy to light up, but the energy it draws is generally more than it really needs. To get the lamp closer to the necessary amount of energy rather than the excess it takes in, a ballast is connected to the lamp. Each ballast type is different but works by adding an electrical load to the lamp and then including a negative resistance and resistors to balance the energy. Inclusion of a ballast will increase lamp life and lower operating costs.
An environmentally friendly solution, James High Pressure Sodium (HPS) Lamps deliver low operating costs and energy-efficient performance.
