Q: 1. will this work with my old compact 600R ? It looks the same...

A: The Profoto Flashtube, 600 Watt/Seconds, UV Coated - for ComPactPlus Monolight, B&H # PRFTUVCPP • MFR # 331511, was the correct flash tube for use with the older Profoto ComPact-R 600 Monolight strobes. Unfortunately, both the strobes and the flash tubes were discontinued around 2010 and are no longer available for purchase. None of the current Profoto flash tubes would be compatible with the older Profoto ComPact 600 monolights, and there are no recommendations for third-party flash tubes for use with this unit. Profoto does not recommend using any flashtubes other than the one that the unit was designed around. Using another flashtube could have adverse affects on the units power board and potentially cause failures.
