New LED Surge Protection Module Offers Lowest Measured Limiting Voltage Available in a 20kA Maximum Current Surge Rated SPD

Low surge let-through reduces driver failure to minimize luminaire damage

CHICAGO, September 14, 2016Littelfuse, Inc., the global leader in circuit protection, today introduced a new series of LED lightning surge protection modules with greater transient overvoltage protection for outdoor and commercial LED lighting fixtures. The LSP10GIHP Series Surge Protection Device (SPD) Module is the only series-connected SPD module on the market that combines low surge let-through (measured limiting voltage or MLV) and low clamping voltage ratings with a built-in LED indicator that alerts maintenance personnel to the need for replacement. This low MLV rating helps protect a luminaire’s LED driver against surge-induced failures and extends its operating lifetime.

For more information on the LSP10GIHP Series, watch the new video available from Littelfuse.

Constructed with Littelfuse thermally protected varistors, this series is available in a choice of operating voltages (277V or 480V). The 277V can be confidently used in 120V and 240V systems. The 480V can be confidently used in 347V systems and some 277V systems. A built-in thermal disconnect function protects against catastrophic failures and fire hazards, even under varistor end-of-life or sustained overvoltage conditions.

Applications include roadway lighting, parking garage lighting, wash wall lighting, traffic lighting, flood lighting, digital signage, tunnel lighting, and street lighting.

“The LSP10GIHP Series offers the highest level of protection from transient surge voltage in the lighting market today,” said Todd Phillips, global marketing manager. “Its low surge let-through ensures the SPD module is compatible with the LED driver it’s intended to protect, giving luminaire designers the flexibility to choose the brand and wattage of driver they want without worrying about whether it will coordinate properly with the SPD module.”

LSP10GIHP Series Surge Protection Modules offer these key benefits:

  • Low MLV and low voltage protection level (Up) reduce driver failure and increase time between maintenance calls.
  • Double-insulated cable wire makes the LSP10GIHP suitable for use in Class II luminaires per IEC/EN 60598-1.
  • A built-in LED indicator saves maintenance time by identifying when the SPD module requires replacement to keep protecting the luminaire.

The LSP10GIHP Series is available in bulk pack. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit
