Warranty period

LED lamps are usuall noted for having a long life. A warranty conditional on a restricted number of lamp operating hours per year should be approached with caution.


It also makes sense to check if the warranty period applies to the entire lamp luminare or just to certain components. The warranty period should cover all parts of a lamp, including its power supply system, which is critical to this category of electric equipment.


It is also good practice for manufacturers to specify the ageing of the LED luminaire in its GT&C. Ageing means the maximum reduction of illumination efficiency over a defined time. This parameter is denoted as LxBy.

Operating limits for LED lamps

Usually, a warranty certificate specifies the requirements for the proper use of lamps. Here, a LED lamp manufacturer should suggest the limits within which a LED luminaire is allowed to operate. This especially concerns the ambient temperature at the luminaire’s installation location.


GT&C also specify the obligations of the guarantor. For lighting products, the warranty service call response time is important. It should be verified. The shorter a service response or warranty replacement, the better the operating safety.
