Mudder Mini Christmas 2.5 Volt Replacement Light Bulbs for Christmas Trees Decorative Light Supplies, 170 Ampere, 0.42 Watt (100 Pieces, Clear)

My tree has lights that are 25 years old and I had a few that either burnt out or the copper wires snapped off from being so old. These replacement light bulbs work fine as replacements but THEY BURN OUT in about four weeks. Plus the two copper wires on the bottom should be a little longer to be ideal. Amazing how my 25 year bulbs last long yet the replacements burn out so fast. No coincidence that five burnt out within four weeks of use. Would love to know how many hours these are rated for from the manufacurer.

Generic lil light bulbs. Tons of them, 100 I think, for a low price.

So these are white lights not the dull yellow kind, we put up 11 trees in our house every year and this time almost every tree had a section of lights that were out but we purchased these replacement bulbs and a light keeper pro and this saved us from having to replace our trees. I’ll likely be buying 3-4 this Christmas just to complete the trees. I spread one container over 11 trees

Work well and easy to install, but not as bright as the other lights on the original strand lights.

The problem I have with these replacement bulbs is that the two wires are not long enough. They barely extend past the bottom of the bases I have in my wreath...maybe an 8th of an inch. You get stuck trying to fold them over the end of the base being that they are too short. Hard to see and push through the base holes. That being said they will light but I dont know for how long since they are barely making a connection in the base. Now I have to spend more money and try the pinched or tapered bottom replacement bulbs to see if they will fit better. FYI...replace your burnt out bulbs as you see them before so many go out you lose the whole string as eventually you will. Bulbs with black spots could mean your cord is on its last leg and should be replaced especially if you have a lot with black spots.

Great bulbs, used them over the Christmas season replacing lights that had burnt out in other strings, saving a few bucks over letting them burn all the way out. Never had a bad bulb out of the pack.

The lights arrived in a bubble wrap envelope. Inside was a box that contained a velvety bag that held the bulbs safely. I counted them and all were in attendance! Began replacing dead bulbs in our pre-lit tree and every bulb I used so far, ~20, has worked as advertised...YAY! I have another string of lights that I scavenged from while waiting for these bulbs, so will be using many more and will report back. Seems like a great product! If I run out of this batch of 100, I will be reordering to have more bulbs on hand, thereby preserving the life of our pre-lit tree!

Bought a small Christmas tree from hobby lobby a couple years ago and half the lights were burned out this year when I went to set it up. These are a perfect replacement. Initially they were brighter than the originals but within a few minutes they were the same brightness. It was a little teadius replacing the bulbs but it helps to have a tool that help separates the bulb from the string.

great price

I had numerous bulbs out on my pre-wired tree. I needed to replace them or the tree. Its evidently their time. After reading reviews of complete bulb and base replacement bulbs, and their needing to be an exact match for the socket. I decided to go the bulb only route. It is a time-consuming process. Getting the bulb into the base, spacing the wires, sliding it into the base, folding the wires. Im guessing I replaced about 60 bulbs, right up to the day the tree came down. I expect I will be ordering a second pack, just to be prepared for next year. They work and work well once you get enough of them replaced. If you have a similar problem, with a large number of bulbs out, I suggest you have a Light Keeper Pro by Ulta-Lit Technologies to assist you. It tests bulbs and helps find where faulty bulbs are located in the string. The instructions and their online videos help explain how the light systems work and how to fix them.
