Cheap & Effective (+ Tips for Finding Burnt Bulbs)
These were compatible with my old pre-lit National Tree with clear incandescent lights. All of the bulbs worked and look the exact same as the originals in brightness and hue. They come in a handy plastic case. Do double-check the tag on your light string to see that the volts and watts match. The bulbs also have shunts (thin coil of wire at the base) that should almost always kick in when the filament of a bulb eventually burns out, so that the rest of the string stays lit, which is essential. I previously tried buying replacement bulbs from National Tree, but they made the husk design smaller in 2021, so these standalone bulbs were ideal and much cheaper (100 for $9 v.s. $52 from the manufacturer). Tips for replacing lights: I tried using a contactless current reader to narrow down the burnt bulbs but it was too sensitive to use on my pre-lit tree. If you notice burnt bulbs, replace them immediately because burnt bulbs cause a voltage increase which dramatically shortens the life of other bulbs on the string. I ended up taking out all 50 lights in the string, testing each on a working string, replacing burnt bulbs with these using the original husks, then placing the 50 working bulbs back in. This was tedious but worked. Or you may be able to just identify dead bulbs by checking if the filament is broken. But so many of mine were dead in the string (>90%) that taking them all out worked better. The relief when you plug in the string and it finally works 😌 These are great for replacing one-off burnt bulbs. If your whole string is out, it’s harder to ID burnt bulbs and you might want to buy a new string. But if you’re patient and have an hour to burn, you can get any string working again.

A MUST buy if you have incandescents
These made fixing my old incandescent lights a freaking BREEZE! Gone are the days of trying to find lights with bases that work in other strands! They shine like any other incandescent and while yes it will be a BIT more tedious to change the bulbs out that beats trying to match bases from different strands! Plus it save you so much money from having to just buy more lights! These are compatible with any incandescent strand! These were a life saver this past Christmas! Our tree has never looked more beautiful now that all the bulbs worked!

Good quality and worked perfectly.
Exactly what I need, none broken, I used 193 of the 200 and all of them worked. These are a touch brighter than the old ones that remain functional on the tree, but blended them in a bit and you can't tell.

So Far, So Good
The bulbs function well to relamp typical light strings and pre-lit trees. The brightness is just fine, matching existing lights well. Frankly, I don't understand the complaints of other reviewers that they're too dim. If you'd needed the typical "2.5V" bulbs, these are it. Apply about 2.5V and they'll be bright enough, matching existing lights. One cautionary note is that the wire leads are cut just a bit shorter than some other applications. Consequently, you might find that the contact questionable in particularly deep sockets? They were fine in any string that I'd tried - just a thought. Now... let's see if they last a few seasons.

Good replacement bulbs
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 I'm 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 we're 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 doesn't mean its right for you. I bought these because they matched exactly what my tree user manual said a replacement should be. If you're 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.

EXACT Match
My pre-lit Christmas tree is 12+ years old and I only recently used the last of the spare bulbs it came with, which was a lot. Initially, I had bought National Tree Company branded bulbs because they were also 2.5V replacements and the same brand as the tree. Well, I was disappointed to discover that they were extremely dim after replacing, so I knew they weren’t the right wattage. The issue is that the both the package and listing for the NTC brand mentioned nothing other than the voltage. After some further research, I found this listing which had a picture of the tag (usually found near the plug) that matched mine exactly—voltage, wattage, amperage. The bulb was an EXACT match. You saved my Christmas tree!

Replacing burnt out bulbs.
Bulbs fit perfectly and were easy enough to change out. Takes time but tree looks beautiful. Make sure you get the correct wattage of bulb. You can usually find it on tree wiring harness by the plug.
