This lamp consists of 3 components: - Ignition device. - Ballast unit - Gas discharge tube The gas discharge tube does not have a filament, but an arc.You can compare this with a welding arc.The xenon gas is located in the arc chamber. The reaction between the arc and the xenon gas causes the lamp to light up white. A high voltage is required to ignite the arc, which is generated by the ignition device. Once the arc is ignited with 30 kV,it can be maintained by a lower voltage and powers.55 V and 35 W. This voltage Is an alternating current that is converted by the ballast unit. The advantage when compared to the halogen lamp is higher efficiency and greater light output. Assess the statements. In the electric arc chamber there are metallic salts and xenon gas. QQ The gas discharge tube operates on direct current. The lamp lights up white due to the reaction between the arc and the xenon gas.

## Step 1<br />The first statement is "In the electric arc chamber there are metallic salts and xenon gas." This statement is not mentioned in the given text. The text only mentions that the xenon gas is located in the arc chamber. There is no mention of metallic salts in the arc chamber.<br /><br />## Step 2<br />The second statement is "The gas discharge tube operates on direct current." This statement is also not mentioned in the given text. The text only mentions that the voltage is an alternating current that is converted by the ballast unit. There is no mention of the gas discharge tube operating on direct current.<br /><br />## Step 3<br />The third statement is "The lamp lights up white due to the reaction between the arc and the xenon gas." This statement is mentioned in the given text. The text clearly states that the lamp lights up white due to the reaction between the arc and the xenon gas.
