LED Keeper LED Light Set Repair Tool

II have used this company incandescent light string repair tool in the past with mixed results and to put it mildly I was very skeptical if this would work. My first repair was to a 70 LED/24 foot outside string that was wrapped on a tree but in 10 minutes it was fixed. I was very lucky on this string as LED's that out were close to the plug on this mounted string. The second set fixed was an unmounted 92 LED/32 foot string and took less than two minutes to repair. With the written instructions and online video you cannot go wrong. The lessons I learned are: -Unmounted lights are easier to repair. The tester comes attached to a 3 foot cord limiting the length the tester can be used. This is only a minor issue and limited to installed lights. It easily found the one broken LED on the 32 foot unmounted string. -Be sure the wire is correctly positioned in the tester before pulling the trigger. It is very easy to incorrectly position/select the wire causing you to repeat the procedure. Although this was identified by another reviewer I still managed to do it. -After correctly positioning the tester on the wire and pulling the trigger you have to allow enough time for the LED's to light on longer strings. -Strings with multiple failures take some extra thought, time and require a little more effort. Initially you will get inconsistent results but if you decrease the number of LED's tested and just work from one end of the string it works. . Bottom line this tester is easy to use, does its job and I would buy it again. I do share the same concerns with reviewer MBR as to fixing or replacing multiple failure strings. My multiple string LED failures were only one year old am questioning the quality of these strings. The common issues for the failures were almost 90 % involving the copper wires where it was bent to be inserted into the LED holder. Note: The write up said it came with 3 1.5-volt batteries are included, In reality it has a 9 volt battery

So this tool helped me repair 3 long LED sets that were completely out. It would have cost me about $75 to replace the sets so I decided to try this tool instead. With it, I was able to find and replace many bad LEDs in the sets so that they worked again. It took me about an hour per set. In the end, I ended up replacing 15 bulbs total. Here's the BIG BUT if you're thinking of buying this. Do you have plenty of LEDs lying around to replace the bad ones? This does not include replacement bulbs. Remember that LEDs are NOT universal. Every set seems to use a different shaped base on its bulbs. I used an x-acto Knife to reshape the bases of the LEDs I had lying around to fit in different sets. On 2 of my other sets, I gave up because the bases were badly corroded. This kit includes 2 replacements for corroded bases so after that what are you going to do? Also, in my case, even though I got the sets working, what happens when they fail again? I'm out of bulbs and once they are on the house, I'm not taking them back down to troubleshoot in the winter. The bulbs are all the same age so it stands to reason that there will be plenty more failing soon. After this season, I will be buying new sets on clearance. So the decision is yours. How old are your sets? Do you have the patience to troubleshoot? Do you have lots of spare bulbs? Are you sure it's just a bulb issue and not corroded sockets? The tool works. Start halfway up the set and work your way down the line. It lights up what works and easily tests individual bulbs once you remove them. It comes with a 9V battery installed and ready to go. If you have lots of bulbs out, test one at a time using the tool crimping the wire until you start finding bad ones (start at the end closest to the plug. Good luck!

I was HIGHLY skeptical about this tool when I bought it, but it does exactly what they say it does and how it is shown in the videos on their website [...] I learned a few things about how it works that might help others use it more effectively. Many of the complaints I read indicate that nothing happened when they squeezed the trigger; others said it was necessary to hold the trigger for a moment. They're correct, and here's why. When it's working, you can hear a high-pitched whine like many voltage-boosting circuits (think about the whine when you turn on a big camera flash unit), and it ramps up over a few seconds until the lights come on (if they do). As far as I can tell, it starts at a low voltage to avoid burning out working LED bulbs. If not enough current is flowing it starts ramping up the voltage. When the circuitry detects that the current flow indicates the LEDs are illuminating, it stops increasing the voltage. This makes perfect sense as a design. If you're on LED #2, it'll light almost instantly. But if you're testing halfway down a 200-bulb string, it's going to take a few seconds before it reaches the proper voltage. Overall it is a brilliant design, but it can confuse the user if you're impatient. So be a little patient while you work. Also, it's easy to THINK you have the wire positioned properly in the test slot. Sometimes it took several tries to get right. Be careful to seat the wire correctly before you squeeze, then as I noted above be prepared to wait several seconds if you're not close to the yellow plug end of the string. I gave it 4 stars instead of 5 for a few design compromises and challenges. It wasn't quite so happy with a 200-bulb string that had a transformer block halfway down. It was very hard to understand what it was doing, and the results were strangely inconsistent. On those multi-segment strings, it might light the left half or the right half, or sometimes parts of both. So the process of finding a failed bulb became much harder than a simple binary search (look it up). It does work, but not as simply as with a shorter string. Also, this tool doesn't instantly fix LED strings with more than one failed bulb. You still have to work until you find all the failures. So this tool will be great to immediately fix a failed string when you're pretty sure only one bulb failed. But if it's an older string with several failed bulbs, prepare to spend some time. I really like the bulb testing slot. I would be happier if it supplied alternating current; as it is, you must try both orientations as only one will illuminate the bulb. But it was still fairly easy to use. I would be a bit happier with a longer cord; I had to use an extension cord at one point when the string was already mounted on a wireframe. Not a big deal, and it was fine for sitting on the living room floor testing an unmounted string. All in all, this is a valuable tool I can heartily recommend despite its minor faults. I think tonight's single string repair paid for half the tool's cost, and it will have completely paid for itself the next time I use it.

I liked that the product did exactly what it was supposed to do. In the past I would have thrown out many strings of LED Christmas lights. I was able to fix every string and therefore saved a lot of money.

I did not use the front wire piercing way of testing my outside string of LED lights; I opted to remove all 50 to test each individual one to find the defective one. The enclosed 9 volt DC battery has a testing spot near the base, and helped me to diagnose the defective one without compromise of the wire insulation. Eventhough it is a 120 volt string, the bulbs are DC powered. A long overdue testing device, a good investment.

the bulb tester is really handy

I ordered this in the summer with the intention of fixing my Christmas lights before the season arrived. Things got busy and I didn't get a chance to try to fix them until this month. I opened up the pakage and tested it on a couple of strings that were only partially lighting up. No matter where I tried on the string it would not light up the good bulbs. I tried changing the battery and even tried it on a perfectly good light string but nothing would light up. I could however test bulbs and fuses so basically what I ended up with was an expensive bulb and fuse tester.

Super facile à utiliser et qualité prix Celui-ci je trouve qu’il est supérieur à l’autre qui est rouge . Cependant ils sont chacun leur fonction
