LED Keeper® - LED Holiday Light Set Repair Tool

There is no way I would have found the four to 6 bad leds in each string. This product is worth every penny. Dont throw out those strings that dont light, spend the $25 and fix em. You can purchase spare diodes on Amazon as well (cheap). Watch you tube videos and understand how it works and youll be a pro in no time. Definitely recommend this.

Driving to my moms and I see a LED snowman sitting on the side of the road with a FREE sign hanging from it. Why not! Get it home thinking I could use my mini light keeper. Nope I needed this one. Since I had success with the mini light, I ordered this one. Took a bit of time to figure it out the process but using the pods, I was able to restore it and it look great! I ordered more pods in case the need ever arises. Highly recommend these repair tools.

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. Theyre correct, and heres why. When its 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 youre on LED #2, itll light almost instantly. But if youre testing halfway down a 200-bulb string, its 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 youre impatient. So be a little patient while you work. Also, its 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 youre 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 wasnt 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 doesnt 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 youre pretty sure only one bulb failed. But if its 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 tonights single string repair paid for half the tools cost, and it will have completely paid for itself the next time I use it.

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.

This light tester saved 5 of my 6 strings of icicle lights! I didnt know how well this would work with icicle lights but it turns out it works great and is very easy to use. When I pulled my lights out this year 5 of the strings didnt fully light so I bought a couple more strings of lights. As I was hanging one of the old string of lights half of that string went out which now equaled 6 total strings that didnt work. I already had it on the house and didnt want to take it down so we decided to get this tester. I tested it out on one of the strings not on the house and BOOM right off the bat I fixed a string. I eventually got on the roof and fixed the string while it was still attached to the roof. Over all I was able to fix 5 of the 6 strings that didnt work. One string even had ALL of the lights out and I was able to fix it! The bulb tester works great and the bulb remover on the end is a finger saver! Soooo glad we bought this! Now Ive pulled all the working bulbs out of my string I couldnt fix and Im going to use those bulbs for replacements down the road. BUY BUY BUY this tester!

The LED Keeper has already saved me over $100 above the cost of the tool. I easily repaired 8 light strings that would have cost $17 each to replace and I still have more to fix. I bought the least expensive one I could find at about $25.

After watching the videos provided by the manufacturer, it took a couple of tries to see how to test the light strings, but in the end it worked and was able to find the bad bulb within about 5 minutes.

I wondered if I needed this tool before I bought it. I had 5 Christmas LED Nets and 2 LED strings that had lights out. I bought the tool and the strings were fixed in about 10 minutes each. The Nets took longer because they were made up of three strings each and two had multiple strings out. Some of the Nets also had multiple LEDs out and I was able to fix them all saving the cost of buying new Christmas lights. The tool was well worth the cost and I am happy with the quality and how well it works and the features it has. I used the wire connector and the LED tester. I did not need to use the fuse tester. I recommend this tool to anyone with Christmas lights that do not work.

Because of the connection on my tree, this device was not compatible.

Heres the deal, I have these lights that I brought last year for my pagan winter solstice display from the Homeless Despot. They arent the greatest lights, but they are LED and they can switch from warm white to multi-color. Anyhoo, one 12 foot section was out, I stood on a ladder and checked every bulb in that sector...no dice . Oh, Mylanta! Went ahead and looked on the Homeless Despot website, and they were out of said lights. Fack! Got on my phone, opened up the A-Zon app, and blammy! Found this puppy. Worked like a charm. Cost less than a new string of lights. Highly recommend.
