IEEE Standards - The Institute of Electrical and Electronics Engineers (IEEE) sets standards for surge protection in electrical and electronic systems, including IEEE C62.41, which provides guidelines for surge environment and protection.

National Electrical Code (NEC) - Adherence to the NEC ensures compliance with national safety standards for electrical installations. Surge protection requirements are outlined in Article 285 of the NEC.

Local regulations - Always check for local building codes and regulations that may have specific requirements for surge protection in lighting systems. Compliance with local codes is essential for safety and legal adherence.

Remember: surge protection devices aren’t foolproof. Sometimes, the protection isn’t strong enough for stronger lightning storms. For example, a lightning strike in Ottawa knocked out the LRT power lines despite having installed surge protection. 

Protect Your Investments With Surge Protectors

LED setups and design elements are investments — you wouldn’t want to lose them to a sudden surge of lightning!

If your LED luminaires are unprotected, be sure to install surge protectors as soon as possible. It’s not 100% protection, but it’ll help you rest assured that your investments have the best possible safeguards against the elements.
