No, given the same lumen rating. Florescent lights are more electrically efficient than incandescent bulbs. Be careful, fluorescent bulbs currently contain Mercury and should be handled and disposed of properly.

What are the most efficient light bulbs?
At present there are several types of light bulbs available for indoor domestic use.Arranged by their efficiency from least-to-most they are:Incandescent bulbs (60 watts)The old style light bulb emitting light from a hot filamentFluorescent tubes (30 to 40 watts)Several inch to several foot long tubes emitting light from a vacuum with a trace of Mercury vapour requiring a special fixtureCompact Fluorescent bulbs (15 watts)Roughly incandescent sized small fluorescent tubes designed to screw into standard light bulb fixturesLight Emitting Diode /LED's (5 watts)Small cool running lights using special mini-sockets or designed to fit into conventional sockets.Notes:Power requirements to provide as much light as a 60 watt incandescent bulb indicated in parenthesesBoth types of fluorescent tubes contain mercury and require special handling and disposal requirementsOutdoor lights would also include Mercury and Sodium vapour bulbs as well as high powered incandescent bulbs. These are more efficient than incandescent bulbs but the colour spectrum emitted and other aspects makes indoor use unlikely
What do light bulbs do?
They use less energy to produce light, and thus save energy and help to save the environment through conserving electricity. The energy efficient light bulb applies fluorescent lighting technology to replace incandescent lighting technology. In the latter, a filament is heated past red hot to white hot to emit useful light. This creates a lot of heat, and is inefficient. The fluorescent tube screws into a socket just like the incandescent lamp, but has electronic circuitry built in to supply the elevated voltages necessary to operate the coiled fluorescent tube. Inside that tube is a gas mixture that is ionized by the voltage, and the ionized gas emits useful light. This process is much more energy efficient than incandescent technology.
Is a light bulb filament as hot as lava?
The filament of an incandescent light bulb is actually significantly hotter than lava. Temperatures may exceed 4,000 degrees in some bulbs.
What type of light glow when the filament get hot?
incandescent lights
Why do LED lamps is as hot as incandescent?
Incandescent bulbs generate light through resistive heating of a tungsten filament, to such a point that the filament glows and provides light. This resistive heating produces large amounts of waste heat and a relatively small amount of power translated into light. In an LED, there is relatively little waste heat, as photons (packets of light) are directly generated. Although it is much more efficient of a light emitter than an incandescent light, there is some small amount of heat generated.
How hot do LED light bulbs get?
LED light bulbs normally don't get hot unlike the incandescent ones.
Do fluorescent bulbs get hot?
Fluorescent bulbs produce less heat compared to incandescent bulbs, so they generally do not get as hot during operation. However, they can still become warm to the touch after being on for an extended period of time.
Do LED light bulbs get hot when in use?
LED light bulbs do not get as hot as traditional incandescent bulbs when in use because they are more energy-efficient and produce less heat.
What is the deference between incandescent and fluorescent lights?
An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.
Do LED bulbs get hot when in use?
LED bulbs do not get as hot as traditional incandescent bulbs when in use because they are more energy-efficient and produce light without generating as much heat.
How hot do LED bulbs get compared to traditional incandescent bulbs?
LED bulbs produce significantly less heat compared to traditional incandescent bulbs. This is because LED bulbs are more energy-efficient and convert more electricity into light rather than heat.
How does an 25w compact fluorescent bulb provides the same amount of light as a 100w filament bulb but use less electricity?
It uses modern technology to give better efficiency. A filament bulb has an incandescent (hot) piece of tungsten wire, which produces light but also heat. A fluorescent bulb uses a different process to produce more light and less heat.

What is the difference between floroscent and incandescent?
Incandescent light bulbs contain a metal filament (normally tungsten). When electricity flows through the filament, it gets very hot, causing it to emit light. They are inefficient because most of the electric power goes into heat. Fluorescent light bulbs contain a circuit that increases the voltage of the electricity, which then ionizes mercury vapor. This ionized mercury emits ultraviolet light, which causes a coating on the inside of the glass bulb to glow ("fluoresce). They are more efficient, but many emit an ugly color of light.
Is the light bulb simple or compound why?
The light bulb is pretty simple, also known as a incandescent light bulb, incandescent lamp or incandescent light globe, they are a source of electric light that works by incandescence (a general term for heat-driven light emissions which includes the simple case of black body radiation). An electric current passes through a thin filament, heating it until it produces light. The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which otherwise would be destroyed rapidly by oxidation. Incandescent bulbs are also sometimes called electric lamps, a term also applied to the original arc lamps. They are pretty simple on how they work, but weve invented new ways of lighting.Almost every news story about global warming recommends that consumers switch from incandescent light bulbs to more efficient compact fluorescent light bulbs, or CFLs. These CFl bulbs are more intercut, and harder to understand how they work for some people. But are CFLs really that good for the environment? Incandescent light bulbs use electricity to heat a filament to a white-hot state, producing light. Yet 90 percent of the energy used is wasted as heat, according to General Electric's Web site. Compact fluorescent light bulbs use electricity to excite gas within a glass tube. The gas fluoresces, producing ultraviolet light which the human eye cannot see. This UV light then reacts with mercury and a phosphorescent chemical compound inside the tube to create visible light. Because CFL bulbs do not use heat as the lighting mechanism, less energy is spent to create an equivalent amount of light.
What are source of visible light?
Sun, stars, planets, moon, light bulbs, fluorescent tubes, LEDs, sparks, LCDs, hot glowing metal.
