// Compliance & quality

LED Certifications & Standards | ISO, IEC, ENEC – Crest

Every Crest luminaire is engineered, tested and documented against international standards, from the bodies that accredit our factory to the photometric, thermal, ingress and lifetime ratings that prove each fixture in the field.

// Accreditations

Standards bodies we build to.

The international and regional organisations whose systems and marks govern how our lighting is made and certified.

International

ISO

International Organization for Standardization, our quality-management and manufacturing processes run to globally recognised ISO systems.

International

IEC

International Electrotechnical Commission, luminaires built to IEC safety and performance standards for electrical equipment.

United States

ANSI

American National Standards Institute, fixtures conform to ANSI specifications for electrical characteristics, bases and colour.

Europe

ENEC

European Norms Electrical Certification, the pan-European safety mark for luminaires and lighting components.

// Test standards & ratings

Proven, rating by rating.

The performance and safety tests every fixture passes, measured photometrics, thermal behaviour, ingress and impact protection, and projected life.

EMC

Interference

EMC

Electromagnetic Compatibility, verified not to emit or be disrupted by electromagnetic interference in the field.

LM79

Photometric

IES LM-79

Standardised laboratory measurement of total lumens, efficacy, power and colour for our solid-state products.

LM82

Photometric

IES LM-82

Characterises LED light-engine flux and efficacy across the full operating-temperature range.

IP66

Ingress

IP66

Ingress Protection, fully dust-tight and sealed against powerful water jets from any direction.

IK08

Impact

IK08

Impact rating, housings withstand a 5-joule mechanical impact without loss of function.

ISTMT

Thermal

ISTMT

In-Situ Temperature Measurement Test, real solder-point temperatures measured inside the running fixture.

TM21

Lifetime

IES TM-21

Projects long-term lumen maintenance and rated life (L70) from LM-80 test data.
