LED certifications

LED Certifications
The electrical performance of the fixture will need to be specified in terms of parameters such
as power factor and leakage current, often arising as a result of local regulations. Whereas
certain certifications may be mandatory, such as RoHS compliance or CE compliance, others
may be the industry norm, for example it may be usual for the product to have a UL listing. It
is incumbent on the end user to be aware of all certifications that are relevant and to ensure at
an early stage that the manufacturer is capable of delivering compliant products. A specialised
fixture manufacturer will be able to work with the end user to ensure that the end product is
properly certified.

Certifications are obtained as a result of product testing by relevant, independent and competent
bodies. The purpose of formal certifications is to ensure that the product meets certain minimum
agreed standards appropriate for the product and its working environment. These standards
cover such things as safety, electrical interference and environmental impact.


It is vital that the fixture manufacturer is aware of what standards and directives must be
met in order to achieve the regulatory compliance. For example, for CE certification the EU
Electromagnetic Compatibility Directive would apply to digital lighting whereas, say, the EU
Pressure Vessel Directive clearly would not. Furthermore, if a particular directive applies to a
product, it must be further established what standards within that directive are appropriate
and what specific tests must be carried out. The certifications required for a given product
are subject to local laws and ultimately it is incumbent on the end user to be aware of all
certifications that are relevant and to ensure at an early stage that the manufacturer is capable
of delivering compliant products.

Other certifications are not legally required, but there may be an industry norm, for example
it may be usual for the product to have a UL listing in a particular category. Again, the fixture
manufacturer will be able to draw on its experience in the field to provide advice on this and
be able to supply the correct product with best practice certifications.
