The hawking radiation corresponds exactly to perfectly normal thermal radiation from a blackbody object, and can be used to calculate the 'surface temperature' of the black hole.

I like it! ...
Also, my current understanding of black hole evaporation is that due to Hawking radiation black holes actually emit energy and will evetually evaporate away due to this loss of energy.
HAWKING RADIATION - Theory that black holes emit radiation like any other hot body proposed by Stephen W. Hawking in 1973.
Hawking Radiation: You are told that once something enters the event horizon, it can never get out. So, is it that nothing can come out from a black hole? Well, Stephen Hawking gave us a surprise answer.
Hawking Radiation
the radiation produced by a black hole when quantum effects are taken into account.
Hawking radiation is a thermal radiation with a black body predicted to be emitted by black holes due to quantum physics effects.
Hawking Radiation occurs when a pair of opposite particles form near the event horizon of a black hole.
Hawking radiation originates just outside the event horizon and, so far as it is understood, does not carry information from its interior since it is thermal.
Hawking radiation is very strange, but undoubtably is a real (albeit minuscule) effect in black holes. There are other weird things that probably are not found in nature. One of these is the wormhole.

The Hawking radiation reflects a characteristic temperature of the black hole, which can be calculated from its entropy. The more its temperature falls, the more massive a black hole becomes: the more energy a black hole absorbs, the colder it gets.
The cameras utilize a 70 mm film format and operate with one of three lenses (50, 100, or 250 mm) to acquire high quality photographs through four viewing ports on the Shuttle Hawking radiation (AS&T Dictionary) The theory that black holes emit ...
Professor Stephen Hawking showed that black holes gradually lose mass, and ultimately evaporate, through the loss of ‘Hawking radiation'.
A remarkable result, also discovered by Hawking's group, is that the spectrum of Hawking radiation is described by exactly the same curve that characterizes emission from any hot body. Black holes emit blackbody radiation! ...
However, if quantum mechanics is also considered, it turns out that all black holes will eventually evaporate as they slowly leak Hawking radiation.
Unlike stellar black holes, primordial black holes create and emit elementary particles, called Hawking radiation, until they exhaust their energy and expire.
According to theory, a black hole of mass M, because of quantum effects, emits Hawking radiation like a black body. The typical energy of photons emitted by the black hole is kT, where the temperature T is given by ...
Cosmological decade 38 - 100 is known as the Black Hole era because black holes will be the only gravitaionally important objects left in the universe. However, Black holes do not last forever. They evaporate under what is known as Hawking radiation.
In astronomy, objects such as stars are frequently regarded as black bodies, though this is often a poor approximation. An almost perfect black-body spectrum is exhibited by the cosmic microwave background radiation. Hawking radiation is the ...
