The Good, The Bad, and The Illegal

Click on Picture for a larger View... These Quartz Yard & Security Flood Lights are Illegal in Southern Arizona because they are not shielded. It is a good idea to use a security light that uses a Motion Sensor so it is only on when needed but use a fixture that is shielded so all the light shines downward.
City of Tucson: Outdoor Lights over 50 watts (other than incandescent) must be shielded. Oro Valley: Outdoor lights over 2,000 lumens must be shielded. Pima County: Outdoor lights over 3,000 lumens must be shielded |
