Group Relamping is a planned maintenance strategy that entails replacing all lamps in a system at scheduled intervals when lamp lumen depreciation and the lamp failure rate make it economical to do so. Majengo Group will create and maintain a database that will include quantity and type of lamps in the various plants, the date of group relamping , number of spot relamping between group relamping and next scheduled relamping date.

At 70% of rated life of the lamp on when 10% of the previous group relamping are logged to have failed appeared to be the  most economical range to conduct group relamping. Our calculations are based on these statistics.

• Fixture Cleaning

Periodic fixture cleaning ensures that all diffusers allow the maximum light output.

• Inspection

Group Relamping will allow us the opportunity to carry out detailed inspections. Through this we will be able to identify defects such as cracked lamp holders and loose wiring.
