Surge Protection for LED Roadway and
Area Lighting Systems (ANSI C136.2)

LED Street Lights

Today's increased reliance on very sensitive electronics makes surge protection an important topic for LED Lighting. 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 Luminaire used in Stadium, Street, Parking, Factory, Bridge and Architectural Lighting 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 luminaires that are designed, and fully tested to comply with ANSI C136.2-2018.

LED Luminaire

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.
