-The second means a termal protection reaching 80ºC generaly in a hot spot on the surface.
-The third means a Independent controlgear, not built in or integrated in a luminaire.
-The fourth is a convination of 2 symbols of IEC 60417, one safety isolating controlgear and the other it`s for short-circuit proof controlgear (inherently or non-inherently)
