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

750 lights later these are a great value. So I have an older tree that seems a bit wider and higher quality than what you can buy from big box stores these days unless you spend $400+. With my tree Im not sure what happened but somehow every single light on my tree, all 750, blew out. Somehow none of the fuses in the plugs had been blown from whatever power surge caused this. So I ended up buying two 400 packs of these lights to try and replace them. After doing about 40 I was ready to give up but my kids for some reason loved this tedious job of changing out tiny light bulbs. With them so excited to do this we spent the next several days and knocked them all out. As you can see in my picture they light up well and look good. Since I was replacing all of them I cant say if they would be the exact brightness of what you may already have but were happy with the brightness shown here. They dont get hot and havent blown out yet. As far as quality goes I had none that shorted out as I was careful to be sure I had each leg wire separated when putting them in the base. Out of the 800 I bought I only found 4 were broken or missing wires. Given the total amount Id expect a few to be bad so 4 is definitely a good amount. I see earlier reviews talk about quality and after using 750 I feel the quality is there. One thing to keep in mind is to check your cord or use manual to see what the specs on your existing lights are such as voltage. Just because it fits doesnt mean its right for you. I bought these because they matched exactly what my tree user manual said a replacement should be. If youre replacing a lot of lights that match these specifications then I think these will work great for you. Just dont get stuck replacing over 700 like me unless you have a few helpers around.

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.

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.

Rather fiddly to use but they worked great and were the only solution because I could not find the same style of light for my prelit tree

I replaced more than 80 bulbs in that string of 300. Clearly there is no noticable difference between new and old or it would look like salt and pepper. Also i regret replacing 80+ bulbs and not buying a new string, because it took forever. But, one less plastic thing in a landfill. I had 3 that didnt light in the over 80 i replaced. They ship as a box of loose lights, so some leads need to be straightened, but so far none were broken.

The pack I got is very dim on a standard 50-bulb string. Theyre the usual brightness on a 25-bulb segment of a multi-segment string. Luckily, I had something with 25-bulb segments. They might be mis-labeled or mixed with bulbs of a different rating.

So far everything is good. I had two orders from different companies. one I have used are great bulbs. the other I have not used, but I good faith that they are also good. these are use for my Christmas lights, in which I have change on an average every year is a couple hundred , when setting up for next year. but mainly I cannot find 2.5 volt bulbs were I live in clear. so I have lots of spare bulbs.

I was worried when I bought these that Id get a bunch of duds since a lot of reviews seem to indicate that that can happen. We just put up our tree last week and a bunch of bulbs were out so I figure it was worth a shot. Well, we got the LightKeeper tester to test each of our bulbs (my kids did most of it). We have used nearly all of the 100 bulbs and did not find a single bad bulb. Not one!? Maybe we got super lucky ... I fully expected to find at least a few. So we are ordering a 2nd set (we used up nearly all of ours fixing the tree). Hope others have similar luck.

Better than buying new tree

Good price
