Bulb

(1)	Elements Xenon gas: Xenon gas activates the initial reaction for rapid illuminating. Molybdenum electrode: anode arcing Metal halide salts: color composing component

(2)	Lightening principle When Xenon gas and metal halide salt will discharge the molybdenum anode in a capsule, it emits light.

2.	Ignitor Ignitor (A) is an electromagnetic transformer that receives current from ballast and boost voltage to light on the arc light source in any environment.

Ballast

(2)	Ballast supplies the stable power to the bulb and the ignitor during initialization and normal state of arc.

Stability

(1)	Durable for vibration as there is no filament.

(2)	Does not operate if polarity are changed.

(3)	Doesn't operate if the input voltage is not in the range of 10-16V.

(4)	Doesn't operate if the circuit is short.
