this is just a small program, which i used for testing, but i think some people might find it useful.

waht it does: it sets all blocklight values in a certain rdius around the player to 15, so you get the maximum light level everywhere.

it will NOT go away by placing/removing blocks or by doing a day/night cycle. you have to use mcedit to update all the block light again.

this could be useful for mapmakers, or for people who are scared of the nicht :D

Source is in the zip file, feel free to take a look at it or use it in your projects :D
