The store owner reported issues with premature lamp and transformer failures of approximately 50 multi head MR-16 low voltage halogen luminaires. Each luminaire had 8-17 lamp heads and the installation was approximately two years old. The luminaire manufacturer in good faith paid to replace all of the lamps and transformers. Six weeks later the customer was complaining that the lamps and transformers were failing again. Wilger was contracted by the luminaire manufacturer to investigae. The fixtures in question were installed at the Hickey Freeman Store on 5th Avenue in Manhattan, NY. We met with the store manager, the lighting designer responsible for the installation and the sales representative for the luminaire manufacturer at the job site.
We examined all of the luminaires and the installation. Based on our findings, it is apparent that there were three issues that need to be addressed. All three issues were due to improper maintenance of the luminaires. The issues were as follows:
Because we were able to determine the root cause of the lamp and transformer failures, we saved the luminaire manufacturer the cost of having to replace the entire installation as well as made the store owner and lighting designer happy.
