Surge Protection for Small Commercial Office Commercial Office Lighting Today's increased reliance on very sensitive electronics makes surge protection an important topic for LED Lighting in Commerical Offices. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©. This page discusses how to best protect your LED Lighting used in Small Commercial Office applications. The latest release of ANSI C136.2-2018 provides surge protection requirements for luminaires and control devices. Based on performance requirements and transient immunity testing, these devices can be classified into three categories: Exposure LevelSurge Rating Typical6kV/3kA Enhanced10kV/5kA Extreme20kV/10kA To maintain the expected ROI, end users should select lights that are designed, and fully tested to comply with ANSI C136.2-2018. Interior Office Lighting This table shows the recommended C136.2-2018 transient immunity levels for common outdoor lighting applications: Lighting Application Electrical Transient Immunity 6kV/3kA10kV/5kA20kV/10kA Building entrance, building exteriorX Parking garage, parking lot, tunnel X Street roadway, stadium, airport X Selecting the appropriate SPD Surge Protective Devices (SPDs) shall be UL1449 Type 4CA or better including Type 1, Type 2, Type 1CA and Type 2CA. Per ANSI C136.2-2018, it should be tested to the appropriate exposure level based on the application or installed location. The UL1449 Type 4CA Surge Protective Devices (SPD) have undergone more stringent safety testing than UL1449 Type 5 Components including the critical abnormal overvoltage - limited current testing. The LED luminaire is tested to ANSI C136.2-2018 with the SPD installed. The coordination of the SPD is key in making sure that the luminaire and control devices pass testing and not only the SPD passes by itself. CITEL can provide manufacturers with full C136.2 surge testing for all exposure levels in our surge laboratory in Miramar, FL.
