Update! We still haven't installed our lights, but that will happen soon. However. We were in a Finnish light store, and they have 12V LED lights! They also sell a transformer to convert the 220V AC to 12V DC. The light will not fit on Watermelon without some modification, they are VERY expensive, but they look wonderful! Well, VERY expensive is relative, they were cheaper than the DR LED light I bought, which is not attractive. Of course, I didn't buy it on sale, but.... https://www.professorled.com/catalog/produc...?products_id=62
They are made in Sweden, so I'm going to look for more when we're there again.
