Standard 12V transformer
Starled presents its standard 12-volt LED transformers
Using a standard LED transformer: This model of transformer plugs into your mains supply and can power several LED bulbs depending on its power rating, which can be as high as 300 W. You can therefore use it to power several bulbs used to light your shelves or the inside of your cupboards. However, do not use it in damp rooms, where a waterproof transformer is required for obvious safety reasons.
