Read the question carefully; it needs some editing. You could mean a couple of different things. You could simply want the speed of light in a vacuum, or you could be asking about the time it takes for light from the sun to reach earth. It is not clear.
at the speed of light, a little over 8 minuets.

No, it takes far less than a light year for light from the sun to reach the earth. In light years, it is a tiny fraction: .00001581 light year. That's a just little more than 1-1/2 ten thousandths of a light year.
The speed of light is 186,000 miles per second, or 300,000 km per second. It takes light from the Sun about 8 minutes 20 seconds to reach the Earth.
Light from the sun because all light travels at the same speed, and the sun is the closest star to the earth, so therefore the light from the sun reaches the earth before light from other (further away) stars
In terms of the speed of light, the distance between the Earth and Sun is81/3 light minutes,or about 0.00001585 light-year.
That will entirely depend on the speed at which you're traveling. If, somehow, you're moving at the speed of light, then the sun is 8.3 minutes away. If you're driving 60 miles per hour, then the sun is 176.8 years away by the most direct route. If your speed is somewhere between 60 mph and the speed of light, then the time required to reach the sun will be somewhere between 8.3 minutes and 176.8 years.
No material object ever moves at the speed of light. The Earth's speed in its solar orbit ... relative to a foolish astronomer sitting on the sun ... is about 29.78 kilometers per second. That's about 0.0001 of the speed of light.

In general light travels at an incredible speed ie 300,000 km per second. This is the speed of light in vacuum and in denser medium it will be a little bit reduced. In glass medium it will become 200,000 km per second. Any way in between sun and the earth the major part of the distance between them will be vacuum and the remaining is occupied by less dense air. So the speed of sun's light would be the same as 300,000 km per second. The amount of time it takes for sunlight to travel from the sun to earth is 8 minutes hense the term faster than the speed of light Sorry friend, it does not mean that light travels at faster rate. The distance between the earth and sun will be that quantity which would be covered in 500 seconds by the light with speed of 300,000 km per second.
Nothing travels faster then the speed of light (according to our understanding of physics)
speed of light
Mercury's orbit takes it from 46 million kilometres to almost 70 million kilometres from the Sun. As the speed of light is 299,792,458 metres per second, this means that the light from the Sun takes between 153 and 233 seconds to get to Mercury. This is between 2.5 and 4 minutes. Almost nothing well-known in the solar system is as far as 1 light year away from the Sun.
