Generally the temperature of the lamp or the ballast / transformer will not rise the material to its ignition temperature, because the maximum temperature of the outside of a (compact) fluorescent lamp or small incandescent lamp is simply too low to do so. Besides there is a difference between the flash-ignition temperature of

The maximum temperature on the outside of the lamp (measured during the bridging test) was 180°C and the ignition temperature of the relevant material is much more than 180°C.
Decision:
As the ignition temperature is not known over the life time, the ignition temperature of the relevant material shall not be considered.
