I'm looking for general tips on light and speaker placement for a lightning effect. I have two Lightning FX boxes and 250w Photoflood bulbs in blue and white. Speakers away from the house aimed toward it to bounce off the structure? Lights mounted on the ground or in a tree? I have a descent sized maple tree toward the center of the front of the house and two smaller dogwoods on each side of the front yard. How can I minimize trick or treaters getting the light blasted in their face as they walk back down the driveway? How about adding a shrub in front of a ground mounted light or mounting the light deep into the tree to get a branch shadow effect? Thanks!
