The 'safety' consideration of leaving modelling lamp on ...IT DEPENDS!
And Wilt means it really depends! Besides quality and service, a top-of-the-line manufacturer like Chimera will provide such details about their SB products. From their FAQ page...
What is the maximum wattage light I can put in a Video Pro Lightbank?
The recommended maximum wattage of a fixture in a Video Pro lightbank depends on the size of the bank and the fixture being used. These are the recommended maximums based on size and tungsten/halogen bulbs:
Video Pro Plus Lightbanks
Video Pro Strips:
Small Strip: 750W
Medium Strip: 1200W
Large Strip: 1200W
Video Pro Shallow:
Small Shallow: 750W
Medium Shallow: 1200W
Large Shallow: 1200W
Your SB being protected from scorching is merely a wattage issue. Protecting your strobe from cooking itself with its modelling light is related to SB size and airflow, active cooling (fan), and wattage of modelling. Strobe temperature due to xenon discharge is also a factor, of course. In the case of quality strobes like Profoto, the head detects overheating for any reason and shuts down. That feature also applies to fanless heads like AcuteB and Pro-B (ask me how I know ).
The hotlight wattage ratings above are none too high: I have strobes with modelling lights almost as hot. I have Chimera and Profoto SB in both strobe and hotlight categories, and use prudence in all combinations. The studio workhorses of panels and reflectors avoid the overheating problem of confining modifiers. The exception is fresnel fixtures which can get hot as a furnace but are made of metal—what a clever idea!
Other than watt rating, there are subtle differences between Chimera SB lines for strobe, hot light, and LED.
