Question: can you use this on miniature light sets ?
Document: I love the extra features - the light puller (not that easy to operate, but does the job), the bulb tester (great for testing the bulbs I pulled out of the very dead set to use as spares), and the fuse tester. The man who invented this may or may not be a genius, but he's one in my book. My only hope is the light keeper pro itself lasts enough years to save enough sets to make the purchase price worth it.
This is a must have - I wish I had this 5 years ago before I threw out hundreds of light sets that were only partially working. This tool is a must have item for the holiday decorator. Youtube video = [...]
I purchased the Light Keeper Pro at the recommendation of a friend of mine. Light Keeper Pro delivers it's promise to restore functionality to your lights. I used it on numerous light sets and it worked perfectly everytime. I was alittle confused at first - but then I watched the inventors video on youtube and he answered all of my questions.
I can't believe this thing. It's magic, basically. We are stunned and amazed and how well it works. Don't ask me how - it doesn't matter. I just saved my pre-lit tree that had two sets out (in a matter of seconds, no mind). Plus 5 other strings of lights. I had two strings that just wouldn't light no matter what. The bottom line is that if a light set is done, it's done.
the light keeper pro, I havent been able to use it yet. You see it is for testing and repairing x-mas light strings, and despite ordering it two weeks prior to x-mas it did not arrive until after x-mas. oops
It really does work and I haven't even used but one feature that it offers.It's a great tool to have if you mess with any Christmas lights. Just know that this only works on incandescent bulbs. If you're wanting to use it on LED bulbs you will need to purchase the LED light keeper which I'm sure would work just as well.
This device really worked. It came with batteries and was ready to use. The instructions were easy to follow and I especially like the bulb puller for use with outdoor lights. I had the outdoor Christmas trees working again in about a half hour. Before reading other customer reviews and ordering this light fixer, I was ready to throw the trees away.
Although it was rough getting started, once we got it going it works great! Love the tool on the gun that helps pry the bulb from the light bulb base. It's kind of like a bottle opener. works great! I've got arthritis & I can work it fine. Since we'll probably use the gun only once a year at most, recommend keeping the white plastic tab where the batteries go so you can put it on before you store the gun.
It seems they change bases and bulb diameters from year to year just to mess us up and make us buy new trees and light strings.Do not use this device on LED strings as the high voltage pulse will destroy LED's. And while I'm talking about LED's, I just want to mention that I think LED light strings suck. They supposedly last 50,000 hours, yet I have strings a couple of years old that have burned out LED's.
I have successfully used this device to repair over 300 problems with miniature Christmas lights. My son decorates his home each year with thousands of lights. When we get the lights out each year, there are always a lot of strings that don't work. I purchased the Light Keeper Pro in an effort to fix some of our problems, but could not completely comprehend the instructions on the packaging.
