Connect the white power supply wire to the white wire from the last fixture with another orange wire nut. Connect the bare copper wires from the power supply and the fixture in the same manner.
Can a fluorescent light work without a ballast?
All fluorescent bulbs require a ballast. All compact fluorescent (CFL) bulbs require a ballast, which is often integrated. All HID bulbs require a ballast, which is sometimes integrated. No LED bulbs require a ballast, although some are engineered to work with an existing ballast.
How does a fluorescent light work step by step?
A fluorescent lamp generates light from collisions in a hot gas ('plasma') of free accelerated electrons with atoms– typically mercury – in which electrons are bumped up to higher energy levels and then fall back while emitting at two UV emission lines (254 nm and 185 nm).

Are fluorescent lights wired in series or parallel?
Magnetic vs Electronic Ballasts Older magnetic fluorescent ballasts are usually rapid start and wired in series. Newer electronic ballasts are instant start (wired in parallel), rapid start (wired in series), programmed start (wired in series-parallel, dimmable and CFL ballasts.
How do you know if it's the bulb or ballast?
Take out your current bulbs and replace them with the new bulbs. If the bulbs fail to light up, then 9 out of 10 times the ballast is culprit. You could also try using a multimeter set to measure resistance.
How do I know if my fluorescent light has a ballast?
Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera. If there are no dark bands on the resulting image, you have an electronic ballast that is likely to work with direct drop-in LED tubes (with caveats: see the next section below).
Do all fluorescent tubes need a starter?
Yes, some fluorescent tubes are able to function without the use of a starter. When your tube works with an electronic ballast it does not have a starter. This is for example the case with high-frequent (HF) tubes.
Why do fluorescent lights need a ballast?
In a fluorescent lighting system, the ballast regulates the current to the lamps and provides sufficient voltage to start the lamps. Without a ballast to limit its current, a fluorescent lamp connected directly to a high voltage power source would rapidly and uncontrollably increase its current draw.
What are the 5 parts of fluorescent lamp?
Compact fluorescent components consist of cover, coil glass tube, phosphor coating, mercury vapor, ballast, ballast cover, and base.
What does a starter do in a fluorescent light?
Fluorescent starters are essential for helping to ignite a fluorescent tube lamp by allowing current to flow through the filaments. This causes the contacts on the batten starters to heat and then open, switching the light on.
Should lights be wired in series or parallel?
parallelThe common household circuits used in electrical wiring installation are (and should be) in parallel. Mostly, switches, Outlet receptacles and light points etc are connected in parallel to maintain the power supply to other electrical devices and appliances through hot and neutral wire in case if one of them gets fail.
Should I wire LED lights in series or parallel?
Series, Parallel, or Series/Parallel? The requirements of a lighting application often dictate what type of circuit can be used, but if given the choice, the most efficient way to run high power LEDs is using a series circuit with a constant current LED driver.

How do you connect light bulbs in series?
A series circuit can be constructed by connecting light bulbs in such a manner that there is a single pathway for charge flow; the bulbs are added to the same line with no branching point. As more and more light bulbs are added, the brightness of each bulb gradually decreases.

How to Install a Fluorescent Tube - LampShopOnline
Installing fluorescent tubes isn't as straight forward as you may think. This article shares insights on how to remove and replace your fluorescent tubes without damaging them and causing a hazard to you and others.
How does a fluorescent light work?
How does a fluorescent lamp work? In a fluorescent circuit, beginning at the left-hand prong of the plug, current goes through the ballast, through one of the lamp filaments, through the closed switch in the starter, through the other filament in the lamp, and out the right-hand prong of the plug.
How to fix a fluorescent light that won't start?
Fluorescent lamp starters are rated by wattage, and it's important you use the right starter for the tube in your fixture. Remove the old starter the same way you removed the old tube, by twisting it out of its socket in the fixture. Install a new one by inserting it into the socket and twisting it to lock it into place.
How to replace ballast?
If neither the tube nor the starter is defective, the problem must be the ballast. To replace a faulty ballast, deenergize the circuit, disassemble the fixture, transfer wires from the old ballast to the new one -- one at a time , to avoid an incorrect connection -- and, finally , reassemble the
What is ballast in fluorescent?
The ballast is a magnetic coil that adjusts the current through the tube. It makes a surge of current arc through the tube when the starter opens, and then it keeps the current flowing at the right rate once the tube is glowing. In most fluorescent fixtures, the starter is an automatic switch.
What to do if a lamp doesn't light?
If the tube, the starter, and the ballast are all working properly but the lamp still doesn't light, check for a defective switch. If the lamp is controlled by a wall switch, replace the switch, as detailed in the next section. If the lamp has a push-button switch, the old switch can be replaced by a new one of the same type. To deenergize the circuit before working on the switch, remove the circuit's fuse or trip the circuit breaker.
What are the parts of a fluorescent light?
A fluorescent fixture has three main parts -- the bulb, ballast, and starter. When one of these components malfunctions, replacement is usually the answer.
How many fluorescent lights can you put on a circuit?
You should be able to add up to eight fluorescent lights on a single circuit. Since most outlets come with a rating of 15-amps, you are likely to not overburden or overload it at that quantity.
How to connect black and white wires together?
Sometimes, there will be no green or bare fixture wire. Strip one inch of the wire insulation on all insulated black and white wires from the fixture and cable. Connect the stripped white wires together, cover them with a wire nut and twist until no bare wire is visible .
How to connect stripped wires to black wire?
Connect the stripped white wires together, cover them with a wire nut and twist until no bare wire is visible. Do the same with the black wires. Near the knockout hole is a small ground screw. Hook the bare wire from the cable to this screw. If the fixture also has a ground wire, hook it to the screw as well. Recheck all connections for errors.
