Definitions for "Group Relamping"
The cost-effective method to replace metal halide lamps, by replacing all lamps at one time
Group relamping entails replacing all of the lamps in a system together after a fixed interval, called the economic group relamping interval. Group relamping can reduce the cost of operating a lighting system while keeping illuminance levels close to the design value.
The method of replacing all lamps in an area at a designated point in the lamp's life instead of individually as they fail.
