Do I Need a Transformer for Outdoor Lighting?

If your outdoor lighting is solar-powered, you will not need a deck lighting transformer. If you are using low-voltage lighting, a transformer is needed. Shop for reliable and consistent AC and DC transformers from top brands like Trex, LMT Mercer, and Aurora Deck Lighting today at DecksDirect!

What is a Transformer for Outdoor Lighting?

Transformers convert the power from your standard house outlet to the lower-level needed to run for low-voltage lighting systems. Landscape lights, security lights, and deck lighting systems most generally require a transformer.

How Do I Choose an Outdoor Lighting Transformer?

Low voltage deck lighting needs an AC or DC transformer to convert the electricity in your standard house outlet into the lower grade required. Shop DecksDirect for rugged and reliable lighting transformers from brands such as Trex, LMT Mercer, and Dekor. In stock and available for same-day shipping, these lighting transformers are guaranteed to be weatherproof and several are waterproof certified.
