I found out about this tool by searching for "troubleshoot Christmas tree lights." I saw many hits about it and watched a couple YouTube videos (which I recommend to learn how to use it). I was amazed that it fixed a non-working section of my pre-lit tree on the first attempt! I had to go to three different stores to find one locally, and finally found them at Home Depot.
Pros: Good Size & Weight, Functional, works as described if you follow instructions, instructional videos on youtube
I had heard of this for some time, but never really had the need for one until this Christmas. I have an animated lit Buck that stands about 3 ft high and 4 ft long. I got old Buck 3 Christmases ago at HD and is a beauty when lit up, and unfortunately this year just before bringing him in for storage for another year, he blew out one whole leg, an entire side and part of the other side. Now let me say there are a heck of a lot of lights on old Buck. So I looked online and found they had this light keeper on clearance and in stock at my local Home Depot. Drove over and picked up two, since they were only 5 dollars each. Just in case one was a dud. It is multifaceted and tests the bulbs, will allegedly start up a string in some cases (I haven't tried this part yet) , and will hum to let you know where electricity stops at in a string. I plugged in old Buck and began scanning and it stopped humming pretty quick at the start of the outage area and didn't start humming again along about 30 of the bulbs, but restarted at the end. I replaced the first bulb after the last hum, nothing. I began pulling and testing the other bulbs along the string, most of which were truly out, some were not. But I still couldn't get Buck to light up in that area. At least the light checker told me which bulbs were out by pulling each and testing individually. I decided to take my time and just try a few a day, changing out as needed, so I wouldn't get frustrated and just shoot old Buck. Every time I would scan, it would still point to that first dud bulb which I had tested and replaced twice. Began taping the replaced bulbs with painters tape so I could tell where I had been. So today I scanned and replaced a few more bulbs and as it turns out, the place where the light checker had kept telling me was the start of the problem never has lit up, but I replaced another bulb on the line that was lose in its socket which was apparently causing the whole area to black out. Buck is up and fully functional again, so I can say this item does what it says it will do by narrowing down where your issue is. I got power humming everywhere but along his leg, which was a big help. I also found that some of the 2.5 replacement bulbs don't have enough wire to make contact in the socket, so I used some of the newer replacement bulbs that came in the 2 by 10 ft net lighting which solved that issue. That may be why that one bulb isn't lighting up, but I am not about to touch anything right now. My beloved Buck is up and running again and that is all I wanted.
Pros: Good Size & Weight, Functional, Lots of Features
What would have taken me hours in the past was cut to minutes with this tool. In the past it would be me and a volt meter going bulb by bulb trying to figure out why large sections of my pre lit tree would not work....now it is done in just minutes....make sure after the lights come back on you replace any dead ones or you will have more go out
I never write reviews but this item warrants one! Been using it for years now. I've purchased them for friends and family, I've posted about it on Facebook. It has saved many prelit trees (mine as well as friends who have borrowed it), outdoor lights, prelit garlands, and numerous decorations. Totally worth it! If you follow the directions you can't go wrong. If your lights still don't work, then they just can't be fixed. This products will fix what can be fixed, but It can't fix something that is beyond repair.
We tested the string of lights and they worked......After staple gunning to the roof line they stopped working? Got the light tester out and read the instructions and used it.............Low and behold they started working. This thing will always be part of my Christmas decoration kit. Well worth the money!
We bought this during the after Christmas sale 3 years ago. It took me 2 years to fully understand how this thing works but it definitely does work. If you have a string that is not working just pull a bulb out and plug the socket into the spot provided on the tester and pull trigger repeatedly until the lights come on. If the string of lights are divided into sections make sure you unplug one of the bulbs that is in the non working section. Make sure the string is plugged in while doing this.
Pros: Excellent Quality, Functional, Well Made, Nice Design
Well worth the money. Not totally sure how it all works but I have a prelit tree and four of the strands were only partially lit. I was prepared to just add new lights when i found this on line. I got in the car a drove to the store immediately. I had every strand but one working in less than five minutes. The one strand i still ended up going bulb by bulb to find the bad connection. The voltage detector was hard to use on the prewired tree because all the wires are so close together. One other suggestion would be to pick up extra bulbs while you are at the store to replace any that are bad. I can see using it for other low voltage projects too.
For $20 and the Home Depot return policy, this is a no brainer. I had, yes now it is working, a GE 150 Pro Line light set with 2 of the 3 sections unlit. I tried the quick fix method as described in the instructions and got 1 working, so now 2 of the three worked. The 3 section did not respond to the quick fix. Using the audible tone procedure, I found the bad bulb and now have 150 lights working. A replacement is $18.98, so the device, after 1 repair cost me $1. The next set will start to save me actual money.
I did contact the company for assistance and they responded quickly and professionally.
This is a great product and a great company.
Go buy one now!.
Pros: Excellent Quality, Well Made, Lots of Features, Nice Design, it actually works!
I don't understand how u can't give this 5 stars. The directions are well written ans if you are confused than go on YouTube because it show you how to use all the options or go on their website. I had several light and other outside nativity set which I can't stand doing every year. All u need is time and 20 dollars. Really the only thing that this thing can't do is solve world hunger. My hats off to the person that thought of this the only problem is I whish I had this last year
I was so frustrated. Our pre-lit tree wasn't so lit anymore. I was going through it trying to find the bad bulbs, but couldn't find them. So, a drive to the Depot. Bought this, and brought it home, not expecting much. It worked perfectly. I had so many dead bulbs, but it found them all. Got some going again, also. Worked just as described.
Saved me from having to try to string new lights on a pre-lit tree.
In our personal situation it would have been helpful if you could read the full instructions before purchase. Over half of our string had blackened/burned out and this tester does not work in this situation. We could have taken it back, but we only paid $5.00 in the after Christmas sale, so it was still worth it for fixing strings that weren't blackened and works great at removing the bulb holder. One important thing we did learn is that it's very important to replace burned out bulbs as the more bulbs that are burned out in the string puts more voltage on the other bulbs shortening the life of the whole string and burning out that string (blackens the bulbs). You should do a yearly check for burned out bulbs or as you see them, which is harder after it's decorated.
Had a cheaper, smaller version of one of these, must have loaned it out and not gotten it back. Wouldn't you know it, strung all the lights on BEFORE testing them and sure enough several strands and half strands were not working. Made a quick call to confirm my on-line order was definitely in stock and went to pick up my new tester. Directions are easy to follow and it worked first time; even though my strands had burned out bulbs the tool fixed the shunt in the bulb socket and they worked. To make my strands last longer, I followed the recommendation and replaced my burned out bulbs before putting the strands away for the season...ready for next year!! I stock up on extra fuses and replacement bulbs at the after Christmas sales...This product is a great time and money saver.
Bought this as a last resort to fix 6 outdoor Chritmas wreaths that each had at least one string of lights out. Worked beautifully on all of them: plugged a bulb socket into the LightKeeper, pulled the trigger a few times, and voila, working lights! Interestingly, a few weeks later sections of the wreaths were out again but could not be repaired by the LightKeeper. It seems that all of the bulbs in the affected strings were burned out. My guess is that so many bulbs were shunted that the voltage got too high and cooked all of the remaining good bulbs.
I was excited to use this tester/repair tool after watching their video but when I performed my first test the trigger would not reset after four or five pulls. After playing with the trigger it reset but the same results keeps occurring. I would have returned it for a replacement but Home Depot said I got the last one and they didn't know how long it would take to get a replacement.
The trigger feature of this product worked very well for me. I was able to restore a dead section of lights that was up on my roof without taking them down. Two trigger pulls and the dead section was restored with the exception of the one dead bulb, which I was able to replace. I was also able to restore a string of lights that has had a very large dead section for many years. Four trigger pulls allowed me to identify about a dozen dead bulbs in the entire dead section.
This tool pays for itself very quickly. Very good value.
After spending several hours trying to fix a pre-lit tree, I decided to purchase the LightKeeper Pro. I was skeptical that it would work (at least the "fix trigger" part), but I thought I could use the voltage detector. I came home and tried the "fix trigger" on one section of the pre-lit tree and it worked on the first trigger pull. After that, I tried it on the top section and it took pulling the trigger about 12 times. Worked great and I went on to fix a few other strands of lights with it!
This tool is amazing. I reserve that for only truly amazing products. My pre-lit tree had a bad string since we bought it at a clearance sale. I had wiggled and messed with every bulb and it still would not light. Using the tool I first discovered that every single bulb on the string was burned out. Not sure how but they were. I went through and replaced every bulb. The string still would not lite. I then did the shunt process which is as simple as plugging the tool into one of the sockets and pulling the trigger a few times. The string spring to life!! Turns out I still had 4 or 5 bad bulbs, went through and replaced them and the tree was perfect. A few minutes later another string went out. Plugged the tool into a socket again, pulled the trigger a few times and back to life it came. This thing is truly amazing!
Pros: Excellent Quality, Sturdy, Perfect Size, Functional, Lots of Features
The best part of this product is that I purchased it online and picked it up at the store. It was great to just go to the service desk and not have to search for this item. The item itself was just awful and I literally threw it in the trash. It was useless.
