If by "commercially" you mean large parking lots and such then yes, I use all the lights I have if it's not snowing but for the residential portion of my jobs I usually only use the headlights and two sets of working lights (front and rear), not the whole carnival. If visibility is good I even turn off the beacon on residential streets. Heck, even *I* find the dang thing annoying. I try to avoid flooding homes with lights when it's not necessary. Another thing is noise, I never drop the bucket or pusher near homes (but do it all the time in commercial areas), if there is something that pisses off clients it's the Bucket Bangin' Bum. I use the extra 2 seconds it takes to lower it in a civilized manner instead of just shoving the stick into float. I know guys who lost contracts over this.
