Retrofit TLED Emergency Lighting Considerations
There are always a few potential compatibility issues that can arise when attempting to retrofit older technology with modern technology. A common issue that arises in applications is when there is already a fluorescent emergency lighting product in place prior to the retrofit.
Previous fluorescent lamp installations may be using an emergency ballast that is incompatible with TLED lamps. In this case, it will be necessary to remove the existing emergency ballast and replace it with an emergency product suitable for the type of TLED lamp to be used (Type A, B, or C). Also, the age of the existing emergency product should be considered. Even if the existing emergency ballast used in the previous installation is compatible with the TLED lamps being used or is over 5 years old, consider replacing it. The end results is a system that should not only provide many years of maintenance free operation, but will also offer the latest technology in light engines and emergency lighting.
Due to lumen efficiency advances in LED versus fluorescent technology, the exact same emergency lighting layout may potentially not be applicable. In some situations, where two fluorescent fixtures were needed to meet Life Safety requirements. However, due to improved lumen output of LED lamps, only one fixture maybe sufficient.
Besides lumen efficiency, light distribution is an important performance factor that also impacts emergency lighting. While fluorescent lamps are essentially omnidirectional, the majority of TLED lamps limit beam angle, affecting the light pattern of some luminaires.
It should also be noted that all TLED types can utilize Bodine ELI emergency inverters to convert a retrofit TLED fixture into an emergency lighting fixture. If there is any doubt, a Bodine ELI inverter, such as the ELI-S-250, can be used to power the entire luminaire(s). Additionally, Bodine ELI emergency inverters offer various features to help maximize an emergency lighting layout such as the ability to power multiple fixtures and select Bodine emergency inverters offer patented dimming technology.
