My track lighting just stopped working. I took it down, checked the connection as well as the switch on the wall. Found nothing. Called Tron and Ali immediately contacted me and we set up an appt. for the following day. He suggested it might be the actual light, so to avoid having to come again to install it, I should buy a another light before he came. What a great idea! Within 1/2 hr, he found the switch was defective and replaced it! I am so pleased with the work. He was friendly and very knowledgeable. I'm handy with small jobs around the house, but electrical problems need to be done by an expert, which Ali was! And I saved money by returned the new light I thought I might need! I will absolutely call Tron again! Thank you!
