What is the maximum temperature limit for combustible materials near lighting fixtures?

The maximum temperature limit for combustible materials near lighting fixtures is established to ensure safety and prevent fire hazards. When lighting fixtures generate heat, it is critical to maintain a safe distance from any adjacent combustible materials. If the temperature around a lighting fixture exceeds the threshold, it can ignite nearby materials, leading to potential fires.

In this context, a limit of 90 degrees Fahrenheit serves as an important safety measure. It provides a buffer to account for the maximum heat that can be safely handled without igniting combustible materials. By adhering to this standard, builders and electricians can ensure that the installation of lighting systems does not pose a risk to surrounding structures and materials, thereby upholding fire safety codes and best practices.

Other temperature limits, such as the lower ones like 80 degrees, would not adequately account for higher heat outputs from modern lighting technologies, while figures like 100 or 110 degrees may pose an excessive risk by allowing temperatures too close to ignition points for common household materials.
