For starters, just about everything.
LED lights have come a long way over the past couple of decades, and these days they are the number one choice for upscale exterior lighting. With traditional incandescent or halogen landscape lighting, every bulb that burned out added an additional burden to the other bulbs in the system – shortening the system’s overall lifespan and creating unsightly holes and bare spots in your lightscape. What’s more, the additional energy needs can cause halogen bulbs to throw out more heat, creating a safety risk outside your home.
With LED landscape and architectural lighting, individual bulbs have a much longer lifespan, reducing maintenance needs and keeping your lighting looking great for longer. And gains in energy efficiency with LED bulbs mean that you can run the exact same lighting design for a fraction of the cost – often 75% to 90% less than a halogen system.
