What are the red and blue wires on a ballast?
2 and 3 lamp instant start ballasts use blue wires for individual connections, and red wires for common connections. Black wire is for line voltage and white wire for neutral.
What are the yellow wires on a ballast?
The common yellow wires connect from the ballast to push-in connectors on one of the right holders of lamp 1 or 2. Two yellow wires connect the common lampholders together.
Can I wire a fluorescent light to a plug?
Having the fixture wired to a plug will allow it to be moved to where the light is needed, and used anywhere there is an electrical socket. Connecting a plug to a fluorescent light fixture is straightforward, but the terminals must be connected properly to avoid hazard from electrical shock.
What are the blue wires on a ballast?
The ballast has a hot and neutral wire at one end to receive power, and two blue wires a red one at the other end to supply power to the lights.
Can one ballast power two bulbs?
The two bulbs will always have slightly different impedances, so more current will flow through one or the other. It’s difficult to balance this out. The condition where one bulb is fired and the other is not is obviously the worst case for this.
How many wires does a ballast have?
Wires on the Replacement Ballast / Transformer The replacement ballast provides 5 wires: black, white, blue, blue (equivalent) and red. Incoming electrical power at the fixture connects to the line BLACK and WHITE wires shown on the diagram.
What is the difference between a T5 and a T8 flourescent bulb?
Difference Between T5 and T8 Fluorescent Light Bulbs T5 and T8 fluorescent tubes are often used for ambient lighting in commercial areas such as offices. T5 fluorescent light bulb is a newer technology than T8. T5 fluorescent light bulb has an efficiency of about 100 lm/W. T8 fluorescent light bulb can reach about 90 lm/W luminous efficacy.
What is the difference between T12 and T8 fluorescent bulbs?
The T12 is 1.5 inches in diameter and the T8 is 1 inch in diameter. The T12 runs on a magnetic ballast and a T8 operates on an electronic ballast. These are the basic different characteristics of each different fluorescent lamp type that is most commonly used in offices and commercial industrial lighting all across the world.
What is better T12 or T8 fluorescent tube?
The difference between T8 and T12 bulbs is that T8 bulbs have a diameter of 1.5 inches, whereas T12 bulbs have a diameter of 1 inch. T8 bulbs are a better choice than T 12 bulbs. This can be easily proved. T8 bulbs have a better color rendering index as well as high efficacy.
What does T8 stand for?
“T” stands for “ Tube ”, the figure behind the “T” represents the diameter of tube. T8 means 8*T, the length for single T is 1/8 inch, 1 inch equals to 25.4mm, so the length for single T is 3.175mm The diameter for a T12 is: (12/8)*25.4=38.1mm The diameter for a T8 is: (8/8)*25.4=25.4mm (1inch).
