Electromagnetic Compatibility (EMC) Testing and Compliance Services For All Lighting Companies

EMC Compliance Requirements are changing rapidly

The new European Electro-Magnetic Compatibility (EMC) directive (2014/30/EU) and the Radio Equipment (RED) Directive (2014/53/EU) provide the key regulatory requirements for EMC and safety in Europe for products which emit, use or could be affected by radio frequencies. For North America - FCC and Industry Canada regulations exist which are different to those in Europe.

Internet of Things (IoT) is driving the new lighting eco-system

The lighting marketplace is facing unprecedented change. The Internet of Things (IoT) is driving new lighting eco-systems. Technology, which for 100 years has been based on a wall switch and ‘glass and metal’, is now semiconductor electronics and software. Lighting as an integral component of IoT is being seamlessly integrated using LEDs, electronic controls, wireless networks and driver technologies. Communications involving radio frequencies is present in more and more products.
