You can't get a wart from a hot light bulb.
the glass gets hot but it does not matter there is no reason one should need to touch the bulb, especially when its new.

No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
The bulb glows because the filament inside ( made of tungsten) get's so hot that it becomes red and starts emitting light. A little of it's heat is also radiated to the glass of the bulb and that's what makes it hot. But it will never get hot enough to melt a rubber band.
The bulb of a thermometer is used as a hot spot or "fire place" because as the temperature rises the bulb is heated which as heats the mercury inside to estimate the outside temperature. So as you see the bulb attract to sunlight to heat itself like a hot spot.
Lightbulbs do get hot when lit - even cfl bulbs get a bit hot.
The 3M 2000 body won't get hot to the touch, but if the bulb cover is removed, the bulb can easily cause a serious burn.
A light bulb turns black when the filament inside it gets too hot and starts to burn, creating a layer of soot on the inside of the bulb.
In simple terms, the current passes through the tungsten filament present in the bulb which causes it to heat instantaneously into red hot to white hot and hence light energy emits.
The bulb of a clinical thermometer breaks when placed in very hot water because the sudden increase in temperature causes the air inside the bulb to expand rapidly. This rapid expansion of air creates pressure within the bulb, leading to its breakage.
