How do you drop the 600-volt output power of a fluorescent ballast to use for an LED lamp?

You don't. The output of a ballast is for one purpose only and that is to operate the lamp that is designed for that ballast. You should be careful with high output ballasts as they can draw enough milliamps to lock your muscles up if the current is shorted through you.

Does a fluorescent ballast use power when no bulbs are in the fixture?
Yes, there is an excitation current that flows through the primary side of the transformer which is located in the magnetic ballast's casing.
How much power does a fluorescent fixture use with no tubes installed For example a switched on 8' fixture with a single tube with an old ballast.?
Depends if ballast is in fixture and switch is on. Several watts if new ballast and perhaps 15 watts for old ballasts....
What is the most economical incandescent bulb 10 watts or fluorescent lamp 10 watts and why?
the most economical is the incandescent bulb because the power of bulb is low only while the fluorescent lamp is low and additional the power of ballast from 10%-20% power consumed.but the fluorescent lamp is 5 times brightly the incandescent bulb.
Why would you have a capacitor in series with a ballast in a fluorescent light?
The purpose is twofold. First it is a transformer which steps up the voltage to an amount that will operate the lamp. Secondly it acts as a resistance for the lamp. Without it the flourescent lamp would keep increasing current flow until it would completely burn itself out.
Can you plug a 220V light bulb into a 240V base?
If it fits and the controlling ballast or electronics is compatible with the bulb type. The 240 volt socket rating is just and indicator of the maximum voltage that can be applied to the socket.

How much power is consumed by a tube light?
One has to specify the size and therefore the watt usage of each type or the light output desired to compare them. Fluorescent tube lights range from 5 to 80 watts including losses in the ballast. Compact fluorescent bulbs range from 7 to over 30 watts in usage with the included ballast. LED's don't have nearly the same light output each, so you need a bunch of them to match output, but if matched use lower wattage because of low heat loss. Once you define the wattage, the total power is in watt-hours or kilowatt hours or some other conversion value.
What the difference between ballast and transformer?
A transformer changes the amperage and / or voltage. It literally "Transforms" electrical energy. A ballast is like a capacitor. Think of a ballast as a short-term battery. It stores power then releases it as needed. A common example of a ballast is on fluorescent lights. Initially, a fluorescent light needs a big blast of energy to excite the gas molecules into emitting photons (light). Then it only needs a small amount of energy to keep the gas molecules in an excited state. However, that power has to be of consistent amperage and voltage. The ballast is designed to do that. The electrical ballast stores energy in the same way that a water ballast stores water for stability. Because the electrical ballast stores far more power than the device it regulates requires, it too provides a kind of electrical stability. That's why you often see a fluorescent light flicker or "lose stability" when the ballast starts to go bad. A transformer transforms voltage and amperage up or down. A ballast provides a stabile power supply.

Is it normal for fluorescent bulbs to start blinking finally go out with the base of it where the glass meets it is black and melted like it was going to catch fire?
When fluorescent tubes become dark on the end where they join the socket , it is time to replace them. You are not getting full light output from the tube, but the ballast is still drawing the same power as it would for a new tube.

At what power factor do commercial 4 tube fluorescent fittings usually operate or can they vary?
It varies based on the ballast. Most ballasts nowadays are "power factor corrected" to try and compensate for the bad powerfactor in switching power supplies. The actual power factor of a individual fixture is entirely dependent on the circuit of the ballast, which changes from design to design.

4 fluorescent lights won't come on and 2 other fixtures do what causes this?
A. no power to the fixture that won't turn on. B bad electrical connection. c. burned out fluorescent lamps d. bad lamp holders e. bad ballast f. etc.
How do you test a ballast for fluorescent fixture?
Turn off the power, remove the bulbs, and remove the cover to expose the ballast. If you see tar leaking from the ballast it is bad and must be replaced. If you see no tar then proceed. Use a multimeter to check for continuity. The yellow and blue wires are the power wires and the white wire is neutral. With the meter set to ohms check between the yellow wire and white wire at the end where it connects to the light. If you get no reading the ballast is bad. Now check the other side where power is coming in. No reading and the ballast is bad. If you get a reading at both ends it is good. Check for loose wires.
How do you install hid lights?
Generally:Disconnect power supply to bulbPlug in HID Kit ballast unit to power supply to bulb. This may require drilling a hole in the rubber or plastic rear coverSecure Ballast unit to the vehicleRemove old bulbPlace HID bulb in holderConnecting output of ballast to HID bulbThis will vary from manufacturer to manufacturer, and your HID kit should come with instructions.
