Actually, the sum of *all* your lights should not be too much over <1,1,1>
as some parts of the image may be saturated. I usually use 0.5-0.7 for the
*brightest* light, and 0.1-0.3 for filler lights.
Remember it's easy to modify light intensity by placing the multiplier
before the 'light vector', like
0.2*<1, 1, 1>
this makes it easier to test different values, especially if you are
experimenting with colored lights.
