Fluorescent lamps can be used in the District of Columbia.
If you were really asking if they can be supplied with direct current, the answer is yes, but they really don't like it. They prefer to be supplied with alternating current, or AC, so you'd have to "chop" the DC or use it to drive an inverter, which will change the DC into AC.
There are florescent lamps and CFL's made specifically for 12 and 48 VDC applications available through specialty alternative energy stores.

∙ 15y agoNo, they are totally AC. The lamps are on the output of a transformer (ballast) the input of the transformer being the line voltage. The line voltage can be many different voltages 120V, 227V, 347V .

Can we use fluorescent lamp in dc?
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.
Is fluorescent lights fixtures ac or dc?
The basic fluorescent light fixture is AC, although there are fluorescent lights powered by DC.
Do batteries provide a DC voltage or an AC voltage?
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
How do you check opera lamps on 1986 fifth ave?
You must first remove the panel on the door which encases the opera lamp. Unplug the opera lamp assembly from the vehicle wiring and check for 12 volts at the plug with a test lamp. If the test light works then you have proper voltage at the plug, if it does not, check fuse number five which controls voltage to the dash lamps, tail lamps, opera lamps, and radio light dimmer. Replace if blown. If the voltage is present at the plug but the light does not work then the dc to dc converter is probably to blame. This is the stick-like device between the car wiring and the lamp wiring which is a shielded (gray) round cable. With an ac voltmeter the output of the dc to dc converter should be somewhere around 200 volts. If this voltage is present the lamp itself is bad. Auto zone has neon tubes in stock in various colors and various lengths which will replace the stock lamps with very little modification. Use the transformer box which comes with the neon tube and connect it to the car wiring. CAUTION: If you use the blue or the red neon tube expect some rookie cop to cite you for operating a red/blue light.
How does clipping circuits work in lab?
A clipping circuit works by the switching action of a diode when it is used in a circuit with a source voltage that changes polarity. In the forward direction, the diode's voltage is added to any dc value that is in series with it. If the source voltage is greater than the dc value at a particular instance, the diode will limit the output to the dc value. Otherwise the output voltage will equal the input voltage.
If AC is replaced by DC in a fluorescent lamp circuit will the circuit work?
No.

What changes are to be made for a fluorescent lamp circuit to work if ac supply is replaced by dc?
A fluorescent light fixture is designed to operate on an AC voltage supply. To have the fixture operate off of a DC supply a power inverter would have to be installed. The power inverter would then change the DC to AC for the fixture to operate. These power inverters are reasonably priced these days and can be bought at most DIY stores.
Can lamp work only on ac?
Depends. Lamps can certainly be built to work on either AC, or DC, or both. But some lamps, particularly those with electronics in them, either a dimmable lamp, or a fluorescent lamp, may only work with one type of electricity.
What type of fluorescent lamp is commonly used in an exterior sign?
A high output lamp with a dc recessed base connected to a high output -10 degree ballast. Anything else will not work properly in cold weather.
Can a fan work on a DC voltage?
Yes, if the fan is designed to work on DC voltage, otherwise no.
Does tube light work with ac or dc?
Fluorescent lights work just fine on DC voltage, BUT one needs a current limited power source to stabilize the circuit against the negative resistance of the gas discharge. This can be done with either a resistor or an electronic circuit. The resistor solution is too lossy because excess voltage from the dc csupply has to be converted to heat across the resistor. Electronic switching supplies could supply a fluorescent light with a dc voltage and current without the losses. But that's technological overkill and most circuits still supply AC.
What is the most common fluorescent lamp found in an exterior commercial sign?
The most common fluorescent lamp found in an exterior commercial sign will be a high output DC recessed base lamp. The ballast will be a zero degree type to allow it to ignite the tube in cold weather down to 0 degrees F.
Will a photocell work using dc voltage?
it creates a dc current
Can SMPS work in DC supply?
Yes. Input DC voltage would be root2 times the input AC voltage.
How can you turn a car headlamp into a desktop lamp?
ITS NOT PRACTICAL BUT FOR THE SAKE OF SOLUTION HERE'S HOW: 1. KNOW WHAT IS THE VOLTAGE RATING OF CAR HEAD LAMP = 12 OR 24 VOLTS DC? 2. KNOW THE WATTAGE RATING OF CAR HEAD LAMP = SAY 100 WATTS 3. KNOW WHAT IS YOUR RESIDENTIAL SYSTEM VOLTAGE = 110VAC OR 220VAC? 4. PURCHASE AN AC TO DC CONVERTER - SELECTABLE 110VAC OR 220VAC INPUT VOLTAGE AND SELECTABLE 12VDC AND 24VDC OUTPUT VOLTAGE WITH A MINIMUM OF 10 AMPERE RATING.
