My scene is approximately 8 units across from compas point to compass point
and about .75 units tall.  My lights are away from the camera and all fall
within a 20-30 unit radius of the logo.  Are these lights way too close?  I
have turned the intensity down for all but one of them - will this
compensate properly for lights that are too close?
