To light up a 300mm, 2500W tube, you need a solid 400V high-voltage kick to start the arc—and keep it alive. Then the ballast steps in to tame the lamp’s negative resistance. Without that, the current would race away and fry the filament in a heartbeat. So yeah, matching the ballast to the wattage isn’t optional. Get it wrong, and the lamp doesn’t just underperform—it dies early.</p>
