The Kable Lite 600W Magnetic Surface Mount Transformer from Visual Comfort Architectural, formerly known as Tech, Lighting can convert the standard 120 line-voltage to 12V to provide power to a Kable Lite low-voltage system. It only works with bulbs that are 600 watts or less. It won’t ruin the surrounding decor, either, because it’s housed within a decorative canopy with a fast-acting secondary breaker to protect against shorts.
