Also question is, how does a ballast work?
Simply put, the ballast is the heart of a fluorescent light fixture sending energy (pumping blood) through the lamp. A ballast provides the correct amount of voltage to start the lamps and regulates the amount of current that flows to them once they're on.
Additionally, how much electricity does a t12 ballast use? The typical T12 four-lamp fixture uses 172 watts of power between the lamps and ballast. LED equivalents typically use only 50 watts, 71% less energy per fixture. [3] Not only are they brighter per watt, they also last longer than even the preferred florescent bulbs.
Likewise, people ask, what is a ballast made of?
This lamp consists of a glass tube filled with an inert gas (usually argon) at low pressure. On each side of the tube you will find a tungsten electrode. The ballast regulates AC power to the electrodes. Older lamps used a starter to get the lamp going.
How many amps does a ballast draw?
A 1000 watt light draws about 9.2 amps at 120 volts (1100 watts / 120 volts = 9.17 amps). See this page for other ballast wattages.
