LED Keeper® - LED Holiday Light Set Repair Tool

Extremely disappointed in this product. Theres so much about its design and function that it makes no sense. Its to the point Im confused about all the positive reviews. Ill go down a list of what is wrong with the thing: - the instructions are terrible. I had to find the official video guide online to figure out how to use it - a string of lights must be plugged into the device meaning the lights will be lit by a 9 volt battery. The battery just didnt provide enough juice to light up the LEDs well enough to tell if the light is bad or dim (because its so dim it doesnt appear to light up) - if the strings wires are twisted pretty tightly (like theyre supposed to) its difficult to slip the wire into the testing hook. and this is the biggest ????? of them all: - the LED keeper cuts through the wires insulation to make a complete electrical circuit which is a stupid and inconvenient method of detecting bad lights. Ultimately what this is going to do is kill the string of lights faster by allowing the copper wire to be exposed to the elements, especially if the string the LED keeper is used to fix is going to be used outside. The LED keeper wasnt able to help me find any bad lights at all. Seriously, youre better off buying a contactless voltage detector and watching a youtube video tell you how to use one to detect bad lights on a string of Christmas lights. Its much cheaper and faster than the LED keeper. To make matters worse, what Amazon shipped me was either used or returned and definitely not new.

A single strand of lights on our Balsam Hill prelit LED tree wouldn’t light when we setup our tree. The tree was purchased in Jan 2021. Using this keeper, we identified the bulb that needed replaced and had the full tree lit in 10 minutes. The clips were so useful!

It does exactly what its supposed to. At the end of the season I had 3 strings of lights that only had half of the bulbs working. I was ready to label the strings and try to hide the dead spots next year. It took a little while to get the hang of it, but by the last strand it only took 15 minutes to find and fix the problem. I actually had 2 bad bulbs on that strand. I cant imagine how long it would have taken without this. Now all of my lights are ready to go for next year. The clamp tester and bulb tester both work great. I didnt get a chance to try the fuse tester and the bulb remover was not the right size for my external light string.

Like this companies LIGHT KEEPER PRO for incandescent christmas tree bulbs which we have been using for years to quickly and effectively show and fix burnt out bulbs, this LED version if INDISPENSIBLE If you own LED light set or LED lighted ornamentals with replaceable bulbs! WILL NOT WORK IF BULBS NOT REPLACEABLE! youll be throwing away your light set AND YOUR MONEY when cheap LED light sets burn out! YES, cheap non-replaceable LEDs DO NOT last 50,000 as LEDs are suppose to! BOTTOM LINE...ALWAYS BUY LIGHT SETS WITH REPLACEABLE BULBS!

We have the gun to fix incandescent lights which is a wonderful product and has saved countless hours, frustration and $$$. This gun does exactly the same thing for the led lights. Super easy to use and saved us a lot of time and $$$ in fixing 3 LED strands that went out this year (due to multiple lights being out in the strand). This tool made it easy and fast to locate the issue to fix! A must buy!

I used this to find bad LED bulbs in net lighting where I had replacement bulbs. It took a little experimenting to figure out how to use it with net lights but it was the same basic idea of a single string light. Once I learned how to follow the wiring, it worked quite well. I had 3 sets of lights to fix. One was fixed within 15 minutes with one dead bulb. The second took a half hour with 2 dead bulbs in the same 50 light section - made it a little trickier. The third set seemed unrepairable with this tool and I gave up. For simple string led lighting (as compared to net lighting), this tool would be very easy to use.

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.

Got this yesterday, have fixed two long strings of light and one string of lights on an animatronic reindeer. Paid for itself in under thirty minutes of use. I highly recommend watching the how to use video on the companies website. I had previously tried multiple fixes to include a multimeter and a non contact electrical tester with no luck. This thing is awesome and does what it claims to do.

Just repaired 8 strings of GE lights that I thought were goners. Some strings had a bad section, some strings only had a short good section. Looked like a nightmare, but wifey said, Lets at least try that tool. Fair enough. Plug a set into an outlet. Mark the start point and end point of the section that wont light. Unplug from wall and plug into the tool. Now, lets say you identified a dark section of 30 lights. Go to the 15th light and squeeze the tester on the wire to that light. In most cases, either lights 1-15 will light, or lights 16 through 30 will light. Lets say lights 1-15 light up. Excellent. Now you KNOW that your naughty LED is hiding among lights 16-30. Time to test again. Where? Split the difference: which in this hypothetical scenario would be around light 23. Squeeze the tester on the wire going into light 23 and... the lights before it or the lights after it will light up! Aha. So your naughty light is hiding among the dark lights... and all you need to do is keep narrowing it down until you hit it. Sometimes you find it quickly, sometimes it takes a little longer. Some of the strings I fixed had 4 or 5 bad lights - which meant doing this process several times, each time on a different section. But I look at it this way: $30 for a tool that just saved me 8x$20=$160 worth of lights. NOTE!! What does a GOOD light look like vs a BAD light? The bad bulb often (not always) has a bad wire on it. To help give you and idea what I mean, take a look at the pictures: One of the wires has burned off of the bad LED. Compare that to the good LED in the other picture: two wires, both intact. Every once in a while (1 out of 15 in my case) you will find a bad LED that looks perfectly good. Fortunately, the tool has a little socket on it so you can test good looking bulbs.

Sometime on Christmas Eve, one of our hanging garlands went 1/2 out. I decided to get the LED light fixer, knowing that we have all LED lights and the cost will be worth it. I followed the instructions in the package, each time seeing what lights illuminated. Eventually I was able to narrow it down to 1 bulb, which I then replaced with a new bulb and my garland was fully lit again! If any lights on my tree go dark, this will be the first thing I try. Id rather replace a lightbulb than my whole tree. Its worth the cost, but it might be something to grab on after Christmas clearance, if you can!
