How to verify lamp manufacturers for their product warranty period?

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.

How to verify a lamp manufacturer for its product warranty period?

Here, the technical specificaitons and power supply system of lamp luminaires deserve priority. The warranty period and its extension, if any, should strictly depend on the properties specific to the luminaire components.

It is important that the LED lamp manufacturer has a contract or another type of agreement with the product component OEMs. It is a testament of cooperation that proves the manufacturer is supported technically and financially in its production, warranty, and complaint handling processes. It is critical when it comes to LED lumionaires, especially their power supplies and LED modules.
