I haven't tested for two reasons. There is no power element. The bulb holder isn't catching onto the main body. And I don't have any films to test with. Having looked on-line I see there are others the same but either incomplete or totally complete up to over £600 + postage. ! So hopefully this would make a good one when added to another incomplete unit. Do you have the missing bits ? It is in what seems to be the original box which is covered in a crocodile pattern material Made in France. I will be in Scotland until next weekend but can hopefully answer questions etc..
