Apart from the directions obsured by the base, then very nearly so. Depends in some ways on the details of manufacture.

Where did Edison invents a practical incandescent lamp?
1859
What is another word for light bulb?
Incandescent lamp
What part of the lamp converts electricity to light?
For a filament-type (incandescent) lamp, it's the filament.
Who was the inventor of the incandescent light bulb?
Thomas Alva Edison invented the first practical incandescent lamp in 1879. Many other scientists created the incandescent lights before Edison did, but those lights were not practically useful.
Is krypton electrical insulator?
Incandescent light bulb"Light bulb" redirects here. For other types including compact fluorescent lamps, see Lamp (electrical component).An incandescent light bulbThe incandescent light bulb, incandescent lamp or incandescent light globe makes light by heating a metal filament wire to a high temperature until it glows. The hot filament is protected from air by a glass bulb that is filled with inert gas or evacuated. In a halogen lamp, a chemical process that returns metal to the filament prevents its evaporation. The light bulb is supplied with electrical current by feed-through terminals or wires embedded in the glass. Most bulbs are used in a socket (a housing giving mechanical support to the bulb, keeping its terminals in contact with the supply current terminals).
How is laser light different from incandescent light?
The intensity of light from most light sources is inversely proportional to the square of the distance from the source. So the intensity two meters from an incandescent lamp is one quarter of the intensity at one meter, and at three meters from the lamp the intensity is one ninth of the intensity at one meter. Laser light ideally has the same intensity at any distance.
What can an incandescent test lamp is used to check?
An incandescent lamp can be used to check continuity of a circuit.
What is equal to 60 watt in CFL?
If the question is what wattage compact fluorescent (CFL) lamp has a similar light output to an incandescent lamp of a given wattage, the ratio is usually about 4. A 60W incandescent can be replaced by an 13-15 W CFL lamp. A 60W CFL lamp can replace a 300W incandescent lamp.
How many lumen in a 25 watt incandescent light bulb?
a 100W incandescent lamp emits 120 candela.lumen is the unit for luminous intensity per steradian ,an lamp emits in all directiontherefore a 16.25watt lamp contains 19.5 lumenAnswerThe lumen is the SI unit for luminous flux -which describes the output power of visible light expressed in photometric units. The ratio of a lamp's output luminous flux to its input power is termed 'efficacy', expressed in lumens per watt. The efficacy for incandescent lamp varies from 5-15 lumens per watt. So the output of a 16.25-W incandescent lamp will be between 80-245 W.
What light sources emits only a continuous spectrum a. hydrogen gas b. mercury lamp c. sodium lamp d. incandescent lamp e. laser?
d. incandescent lamp
Is CO2 emitted by incandescent bulb?
No, carbon dioxide is not emitted by an incandescent lamp.
What are five common types of light bulbs?
there are 98 different kinds of light bulbs. including colored light bulbs
Why is an incandescent lamp cool to the touch when it gives off heat?
An incandescent lamp is not cool to the touch unless it is an extremely low wattage. Heat given off by incandescent lamps is one of the drawbacks of the lamp. Total overall efficiency is reduced by the wasted heat.
Why was the incandescent lamp not used in homes?
The incandescent lamps are very frequently used in all the buildings !
Who was rewarded for his patent incandescent lamp?
Alexander Lodygin
Where did Edison invents a practical incandescent lamp?

What was the first name of the light bulb?
The Incandescent Lamp
