Since end of the year 2020 the energy recovery linac project bERLinPro is officially completed. But what is the status of this facility, the next scientific goals in the framework of accelerator physics at HZB, what are the perspectives? To reflect the continuation of this endeavor and the eventually broaden application of this machine from high current SRF based energy recovery concept to an ultrafast electron diffraction facility producing shortest electron pulses, the facility is now named Sealab, Srf Electron Accelerator Laboratory. In this talk, an overview of lessons learned so far, the status of the machine, the coming set up and commissioning steps with an outlook to midterm and future applications will be given.
