One hour after calling John, our job was finished! One of our downlights burned out, John diagnosed…read morethe problem over the phone and came straight over to fix the light. He also advised us to apply the same fix (new transformer) to the other three downlights, thus reducing our electricity usage from 200 watts to 20 watts for the four lights. His fee was very reasonable. We will definitely bookmark his Yelp page and call him again.
