Yes. Many 12 volt bulbs get very dangerously hot, for instance the 12 volt bulbs that are commonly used in vehicle headlights and in small 12 volt 50 watt overhead ceiling lights in homes.
This depends on the bulb design. A simple tungsten filament bulb might have a surface temperature of the bulb well above 100 C. A fluorescent lamp will be much cooler for the same light output.
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
When electricity flows through the filament in a light bulb, it heats up due to resistance, becoming white-hot and producing visible light. This light is what we see when we turn on a light bulb.
The part of an incandescent light bulb that gets hot and produces the light is called the filament.

You can't get a wart from a hot light bulb.
This depends on the bulb design. A simple tungsten filament bulb might have a surface temperature of the bulb well above 100 C. A fluorescent lamp will be much cooler for the same light output.
To calculate the temperature of a light bulb, you can use the Stefan-Boltzmann law, which relates the temperature of an object to the amount of radiation it emits. You would need to measure the power output of the light bulb and its surface area to calculate the temperature. Keep in mind that the temperature of a light bulb can vary depending on factors like the type of bulb and how it is being used.
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
If the type of light bulb you are using was made to run on 1.5 volts, a 1.5 volt battery should be able to light up one or several of those types if they are each wired in parallel directly across the 1.5 volt battery.If the type of light bulb you are using was made to run on 0.75 volts, a 1.5 volt battery will light up two or more of those types if they are wired in pairs in series across the battery.If the type of light bulb you are using was made to run on, say, 3.0 volts, a 1.5 volt battery will not light it up very much - it may just glow dimly.If the type of light bulb you are using was made to run on any voltage higher than, let's say 5 volts - for instance a standard 120 volt household bulb - then your 1.5 volt battery will not be able to light one of those up at all.Another answerYou can wire any number of 1.5v bulbs in parallel, but for each one you add you will draw more current. Draw too much current and the battery will get hot and may explode, depending on what it is made of.How long the battery will be able to keep the light bulbs lit will depend on the size of the battery, meaning how much charge it can hold. (Its capacity in amp.hours.)
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
In an incandescent light bulb this is the filament. It is usually made of tungsten.

The surface of a typical incandescent light bulb can reach temperatures around 200-300 degrees Celsius (392-572 degrees Fahrenheit) during operation. LED bulbs, on the other hand, generally operate at much lower temperatures.
The hot surface indicator light stays on to alert you that the surface is still hot and may cause burns or other hazards.
