RAB Lighting has announced an LED lifespan rating of 100,000 hours for its full line of LED fixtures.
This announcement follows the recent publication by the Illuminating Engineering Society (IES) of Technical Memorandum 21 (TM-21) that provides guidance for calculating LED lifespan and sets a standard by which all LED fixtures can be judged.
The 100,000-hour rating applies to new and previously released LED products. This means that with an average daily use of 10 hours, RAB LEDs are rated to last for 27 years.
The lifespan of an LED is highly dependent on the thermal-management design of the fixture in which it is installed. If an LED is allowed to overheat it can burn out in a matter of minutes. The long lifespan of RAB LEDs are a function of the heat management of the fixture designs.
RAB engineers utilize state-of-the-art computational fluid dynamic software to study heat movement and airflow around LED fixtures. This helps them to achieve the best possible thermal-management designs while still keeping costs to a level that enables quick return-on-investment for end-users.
“TM-21 puts a stake in the ground and levels the playing field for LED fixture manufacturers,” says Ross Barna, CEO of RAB Lighting. “RAB takes enormous pride in designing LED fixtures that perform as great as they look, so it was very gratifying to learn that our adherence to the strictest design standards and our LM-80 tests exceeding 10,000 hours have finally paid off. We are confident that this proves that RAB’s LED products offer a long, useful lifespan and fantastic value to end-users.”
