LED lighting is new technology that has finally gone main stream within the landscape lighting industry. L E D landscape lighting lasts 4 times longer than traditional outdoor lighting.
LED lighting uses 5 times less electricity than traditional low voltage lighting. Led light bulbs last about 8 years and now come with a 5 year warranty. As in comparison to traditional halogen lighting where bulbs last 14 months and have no warranty.
Now any halogen landscape lighting system can be converted to LED lighting by just changing bulbs. It is definitely cost effective to make the change. I converted my house from halogen to LED 3 years ago and went from using 466 watts to 66 watts and still have never changed a bulb.
