The stated wattage does not determine product life. Long-term reliability is the result of thermal design, driver quality, LED operating conditions, installation and the ability to service the fixture.
Heat is the first hidden variable
LEDs generate less heat than traditional sources, but the heat they do generate must be transferred efficiently. When junction temperature rises, lumen maintenance, colour stability and component life can suffer.
- Correct COB-to-heat-sink contact
- Adequate aluminium mass and surface area
- Space for air movement around the fixture
The driver is equally important
A reliable LED paired with an unsuitable driver can still fail early. Driver temperature, voltage range, component quality and protection features matter.
Running components at their limit reduces margin
Designing a fixture with reasonable electrical and thermal headroom generally improves stability. Maximum output on paper is not always the best long-term configuration.
Installation can damage a good product
Loose connections, voltage fluctuations, insulation covering the driver, moisture and incorrect cutouts can create failures that are not visible during initial testing.
Serviceable systems protect the project
Front-openable, modular fixtures allow replacement of the affected component without disturbing the ceiling or discarding the complete body.
