I needed a hood with 12 V lighting. After the conversion it beeped because the built-in transformer only 12V AC supplied. So what new had her low minimum power and as small as possible to fit back into the cooker hood.
The transformer is nice and small, is barely warm (= little power loss) and met so perfectly its purpose. As the only two days is built for durability, I can not say anything, I'm here if necessary an addendum.
