I have a number of florescent fixtures in my shop and one of the ballasts has gone bad. (I assume that because all four bulbs stopped working and I confirm that I have 120V at the power supply with multimeter. Also the bulbs work in another fixture. So…I bypassed the ballast and wired directly with Black power wire to one tombstone end, and white to the other. Confirmed I have 120v with multimeter from end to end between tombstones. I installed a Type A LINEAR LED tube in the fixture but it doesnt work. I confirmed the bulb is good because I installed it in another fixture that does have a working ballast and both LED and Florescent bulbs installed and all are lit up. Thinking I might need both bulbs installed to complete the circuit I installed a second bulb in the fixture- still didn’t work. It should not have needed that because I know I have 120v from end to end. Do type A linear LED’s require a ballast? What am I missing? Thanks!

Hi there, Single mom with 3 young kiddos. The 4 of us hung icicle lights across the front of the house this afternoon. We have a front door light that has an outlet inside it, so I ran an extension cord from that outlet down to the ground. On the ground I attached a timer. To the timer I attached one of those 3 outlet plug splitters. Then I plugged in a single strand of non-LED lights in one of the three outlet spots. That single strand of lights worked perfectly and is still working perfectly. Into one of the other outlets in the line of 3 outlet spots I plugged in an extension cord. That extension cord ran on the dry ground across the front of the house to a second extension cord which also ran across dry ground to the other end of the house. I plugged the LED icicle lights into the far end of that second extension cord. So there was an extension cord coming down from the power source, a timer, then two extension cords across the ground, and then finally the LED icicle lights. When I flipped the inside switch to turn on my front door light, nothing happened because the timer was not set to on. The second I flicked the timer to on I heard a POP! sound like a lightbulb burning out. It was light outside and I was facing the non-LED lights at that moment, which came on just fine. I don't know if the icicle lights came on for a second, but when I turned around and looked, they were off and a cord at the very end of the lights was hanging. Upon inspection I found that the cord for the icicle lights had burnt straight through 1 cm after the male end of the icicle lights plugged into the second extension cord. I live in Denver and it is bone dry here right now, so there was no water. Any ideas why this would happen. I was able to unscrew the last segment of the icicle lights which just served as an adapter from a 2-prong coaxial end to the traditional 🔌 . I found a replacement piece online, which will be delivered in 2 days. Is it okay to try again with the new piece? What happened? I don't understand. I also looked around the house for any piece of plug in equipment that I wouldn't be sorry to see go up in flame. I found a curling iron and did exactly the same thing in the same order with it. I turned the timer to off, turned off the front door light, then plugged the curling iron into the same end of the two ground extension cords. Then I flipped on the front door light and then toggled on the timer. The curling iron turned on just fine with no problems. Finally, there is an oval shaped box thing that is in the middle of the fried portion of icicle light cord. Don't know if it is an adapter or what. Do you know what that is? Thanks for any insight you can give! [img]https://cimg9.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/christmas_light_issue_692a949975f6279834141658e2e9b98c243bc763.jpg[/img]
