Sony Battery Video light (Model HVL-50DA)

I'm looking to sell a Sony Battery Video light, this is the HVL-50DA model number, I'm not sure if it is working or not, as I don't have a battery to test it with, but it is in brand new condition and the filament on the bulb looks fine.

Can be sent via Fiks Ferdig or pick-up locally in Ås or at Nydalen in Oslo
