Types Of Ballast For Fluorescent Lights

All fluorescent light fixtures consist of at least lamp s lamp holders ballast and internal wiring.

Types of ballast for fluorescent lights.

A fluorescent fixture requires a ballast to send the proper amount of electricity to the fluorescent bulbs. For the fluorescent family both t12 linear fluorescents and two pin cfls use magnetic ballasts. By selecting a ballast with an ideal ballast factor you can optimize the light output of your fluorescent lighting system and maximize your energy savings. Ballast factor and light output.

A resistor of about 10 kω is required to be connected in parallel with the fluorescent tube to allow reliable firing of the quadrac at low light levels. The ballast provides enough voltage to start the fluorescent bulbs and once they are. In time the ballast may need to be replaced. Magnetic ballasts are the older ballast technology.

Ballast designs using different lamp starting strategies. There are four basic types of fluorescent ballasts. Tube lights also known as linear light bulbs are frequently used in office buildings kitchens work spaces and commercial installations as well as homes with varying sizes and brightness levels this guide reviews the different types and configurations of tube lights both fluorescent and led so you can choose the best tube lights for your light fixtures and other lighting needs. The ballast is used to create the voltage and current necessary to start and illuminate the fluorescent lamp.

Ballasts have a wiring diagram to show how they connect to the lampholders. Fluorescent lights use either an electronic or a magnetic ballast. An older magnetic ballast produced by advance transformer co used to support a 30 watt or 40 watt rapid start fluorescent lamp. The low frequency electronic ballast is a variation of the magnetic one incorporating some electronic components.

For hids some metal halides and hps lamps. Commercial cfls use a separate ballast. There are two different break downs of fluorescent light fixture ballast types as we explain here. There are two lamp families that work with a ballast.

And there are two types of ballasts in each family. The magnetic ballast is capable of withstanding exposure to fluctuations and transients within an electric system along with temperature extremes. A quadrac type light dimmer can be used with a dimming ballast which maintains the heating current while allowing lamp current to be controlled. Nowadays magnetic ballasts are a rather outdated technology that manufacturers are phasing out and so they re usually only found on older types of lights.

Instant start electronic ballasts use a high starting voltage about 600 volts to start very quickly less than 0 1 seconds. There is no preheating of the electrodes for the.
