LED Keeper® - LED Holiday Light Set Repair Tool

Awesome product. I used on four light strings and it helped me solve the problem with each. Each string was $16 a piece and were only one year old. It has more than paid for itself already. Just follow directions provided. Not sure about all detecting all defects but each of mine had LEDs the had one contact broken off which caused one section of the string of lights to not light. This tool helped me identify which LED was defective through process of elimination. Each string took about 5 minutes total to solve.

Found and fixed the broken led bulb within seconds. Must have product if your buying LED lights.

Great little device to save time and money instead of buying lights every year when a half of the string dies and you cant figure out which bulb is bad. There is a learning curve if you follow the instructions. But once you get the hang of it you can go through a string of bulbs in a matter of minutes and find your bad one. Brought back to life six strings of lights that I knew were bad. It has the function to test the lightbulb, fuse and the string of wires. Good investment instead of having to run out and replace your lights.

I had my led light strand fixed in an about 10 minutes. Read the instructions which are folded inside the purple/yellow cardboard inserted in the package. It’s not intuitive, but once you read the instructions, it will all make sense.

Couldnt get to work at first, and almost threw it in the trash due to frustration. The video tutorial was helpful, but could get no lights to light up at all, on a working or non working strand. Decided to change the 9V battery, even though the red indicator light turned on when I squeezed the trigger. So CHANGE THE BATTERY before you get mad and throw it away. Was fairly easy to work after that. Although still required some effort because I found I had multiple bulbs out and a bad socket on a single section of strand.

It’s amazing tool! I liked the way in which ULTA engineers have designed their bad LED searching feature. Dividing the string into the segments and then powering the selected segment from the tool instead of the AC outlet - is a brilliant idea! Before this purchase, I tried to find the broken LEDs manually, but there were too many of them. But it took me only about an hour to test and fix the entire string with ULTA tool. I found 12 bad diodes out of 300 in my string. The major problem with my LEDs were the resistors, connected to them. Unlike the LEDs themselves, resistors wires have been made from the bad metal which got corroded. I liked the individual LED and fuse testing features, found them ergonomic and convenient. I am very happy with my purchase, it is a money well spent.

Overall this is a must have if you have led Christmas lights. Super easy to use. Lots of great YouTube videos on how to use. The only reason I gave 4stars instead of 5, is the manual does not mention how to use the fuse and lamp tester. After watching a YT video, I quickly understood how to use the device. I super quickly fixed a string of lights.

I have the other light keeper and it has saved me money so i figured I would give this a shot. I saved 3 out of 5 strands. And maybe couldve saved them all but I ran out of replacement bulbs. Please give this a try(it does require some patience) I doubt you will be dissappointed. minus one star because 9v was do a
