One of the most memorable moments involving a lightsaber is when it cuts through a thick metal door. The ability to melt through such materials suggests that the blade's temperature must be incredibly high, likely 20,000 to 25,000 degrees Celsius.
Summary of the estimated temperature of a lightsaber
Based on the energy needed to create a plasma state, we estimate that a lightsaber blade would be around 1 million degrees Celsius, several times hotter than the surface of the sun.
Because it is made of plasma, the blade of a lightsaber is heated to tens of thousands of degrees Fahrenheit; in fact, some Star Wars sources have indicated the average temperature is something like 20,000 degrees..
Well, sabers come in a variety of forms, and each has a certain range of temperatures. The temperature of a typical medium-sized blade can reach ten thousand to twenty thousand degrees.
Pretty much anything that a lightsaber touches is immediately converted to a molten liquid or a charred crisp, and when one lightsaber clashes with another, a flash ensues that is so bright that it momentarily saturates one's entire field of vision. So yes, in addendum, lightsabers are really, really hot!

How hot is Anakin's lightsaber?
One of the most memorable moments involving a lightsaber is when it cuts through a thick metal door. The ability to melt through such materials suggests that the blade's temperature must be incredibly high, likely 20,000 to 25,000 degrees Celsius.
Given how lightsabers work in Star Wars, it may seem like the physical slug would just incinerate on impact. However, the lightsaber would actually melt most of the bullet into molten metal. If the lightsaber wielder wasn't careful, bits of the hot metal could fly directly into their face or body.
The only possible way for a lightsaber to harm Superman would be if the crystal powering the lightsaber were made of Kryptonite. However, that would still credit the Kryptonite crystal, not the actual lightsaber. Unfortunately for any Force sensitive that encounters the Man of Steel, Superman wins.
If plasma touches water, it causes water around it to boil. At roughly 1000 degrees Celsius, that water becomes plasma itself. In the aforementioned Star Wars: Clone Wars scene, Kit Fisto's lightsaber causes the water around it to boil.
One important note about lightsaber wounds was that they rarely bled profusely, even when a limb had been severed. This was because the energy blade cauterized the wound as it passed, and thus even a severe wound did not tend to bleed heavily.
Mace Windu's purple lightsaber is a rare and powerful symbol within the Jedi Order. The purple blade, a mix of light and dark, represents Windu's mastery of both sides of the Force and his creation of the Vaapad combat form. His lightsaber is not just a weapon but a symbol of his wisdom, strength, and balance.
It's doubtful a lightsaber would pierce Hulk's skin, and even if it could, Vader would have to get close to use it and it would probably take a while. Even a Force choke wouldn't work against the Hulk, as he can hold his breath for a very long time.
The study suggests that, against all expectations, red lightsabers may actually be the weakest of the lot. This revelation invited us to venture beyond the realms of science fiction and embark on a journey of scientific exploration. Enter Luke Willcock, the mastermind behind this revelatory study.
Dr. Kaku thinks we probably could if we build a lightsaber blade with hot plasma heated to around 12,000°F, contain it on a ceramic rod with an electromagnetic coil, and power everything using trillions of nanobatteries. The technology necessary to create Dr. Kaku's version of a lightsaber does not exist—yet.
Bleeding was the process that a dark side adept used by way of the dark side of the Force to bend a kyber crystal to their will, turning it red. It was possible for some light side users to purify corrupted crystals, which would bring them back to the light side and change their color.
The Forbidden Forms were forms of lightsaber combat used by the Sith during the Sith Wars. According to the testimonies of the Jedi Cervil the Uncanny, lightwhips—a lightsaber variant with a flexible blade—were used to defend against Sith Lords who utilized the forms.
The plasma that comes from a lightsaber blade: Can cut through pretty much anything it touches. exceptions include Beskar, or Mandalorian iron, the strongest metal in the galaxy, as well as the scales of a Zillo beast.
Beskar. The most well-known example of a lightsaber-resistant material, beskar is inexorably tied to Mandalorian culture. The iconic Mandalorian suit of armor, made famous but Boba Fett, Din Djarin, and Sabine Wren, is traditionally made of beskar and is passed down through Mandalorian clans for generations.
Edit: ^they can't block bullets(slugs) with a lightsaber! Since the slugs are physical projectiles, they'd be easier for Jedi to stop using the Force. Actually, issue #18 of Dark Lord of the Sith confirmed that lightsabers couldn't block slugs…not that it wasn't common sense to assume before then.
No, lightsabers can't block bullets. Here's a great video that explains why. The idea was actually put into issue #18 of the Dark Lord of the Sith comic series. During the hunt on Chandar's Folly, Tarkin's team armed up with slugthrowers (firearms) and flamethrowers, two things Vader couldn't block with his lightsaber.
