Yes, vacuum tubes in computers burn out. Transistors are much better. Vacuum tube computers no longer exist except in museums. Vacuum tube computers were originally made in World War 2 to calculate the positioning of antiaircraft guns. It was not necessary to know where the airplane was but where it would be when the explosive arrived. That was especially true when the Germans developed the buzz bomb going 450 miles an hour. When hundreds of transistors could fit in the same area as one vacuum tube, the vacuum tube vanished.

Do all vacuum tubes light up?
No, there are some cold cathode vacuum tubes. These do not light.
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
The gas that is used for incandescent light bulbs and radio tubes?
Argon and nitrogen are the two main gases used in bulbs today.See related links below
How much electricity does a T8 32w fluorescent light bulbs use?
These tubes need a ballast to operate the tubes. The current and voltage will be marked on the fixtures ballast.
What advantages do fluorescent tubes have over incandescent bulbs?
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
What are the benefits of vacuum tubes and light bulbs?
They enable us to do things at night.
Is argon used for?
1) electric light bulbs 2) fluorescent tubes 3) radio vacuum tubes 4) welding
What was argon used for?
Electric light bulbs, fluorescent tubes, and radio vacuum tubes and as an inert gas shield in arc welding.
What are the characteristics of computers based on vacuum tubes?
Overall, computers with vacuum tubes were not reliable nor did very much. Vacuum tubes took up lots of space and got very hot. The lifespan of vacuum tubes were not much better than incandescent light bulbs, and if a computer had hundreds of these, the odds of one going out soon would be quite high. The vacuum tubes didn't switch all that fast either, and they had to be heated before they could be used, meaning it took about a minute or so before anyone could attempt to boot it.
