Abstract

A lighting system () comprises at least one lamp () and a processing unit () for estimating an end-of-life of the at least one lamp (). The processing unit () is configured to receive a lamp burning time during which the at least one lamp is turned on and a forecasted temperature over a selected period of time at a location of the at least one lamp. The processing unit () is configured to estimate the end of life of the at least one lamp based on the lamp burning time and the forecasted temperature. By using the forecasted temperature, use of dedicated lamp sensors measuring internal parameters of the lamp usable for the end-of-life estimate may be avoided and the estimate may be simplified.
