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

Improved metalhalide lamp, comprising: a glass housing and the conductive glass enclosure; quartz discharge tube in the housing, having a pair of spaced apart electrodes connected to the conductive body so that the discharge during operation of the lamp. There is a discharge arc chamber; arc chamber with a medium to generate and sustain an arc, the sodium, scandium, lithium, dysprosium and thallium halide selected from argon and xenon, and a quantity of gas filling of the lamp voltage reaches a predetermined value of the mercury composition . In the preferred embodiment of the invention, the halide is iodide, the molar ratio of each component is 24-44:1:9.5:> 3 <4, the amount of thallium then take the arc tube volume 0 .35 to 0.45mg/cm3
