In fact, connecting your LED lights directly to220V household voltage can damage them or reduce their efficiency and lifetime. Silumen offers LED transformers that can transform 220V into 12V, 24V, 40V, 60V or 80V depending on your needs or the equipment you use. They can also support power ranging from 3W to 24W. We also offer different models of spotlights that you can connect to these transformers. Our LED spotlight transformers are suitable for surface mounted LED spotlights and RGB LED spotlights. All our LED spotlight transformers are IP20 certified, which protects them from solid objects in the long run, thus ensuring their reliability and long service life.
