Trouble with box lights

[palistov]

Don't use box lights except to create an ambient light level across an entire map. As you mentioned, the contrast between the inside of the boxlight and the outside is VERY noticeable.

My suggestion is to use a low level box light (RGB values of 0.05-0.08 and an alpha of 1), and to create a bright area, use a point light with an appropriate light level and radius.
