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. ## Features - What you will get: you will receive enough replacement light bulbs in total, sufficient quantity to meet and satisfy your replacement supplies in daily life - Details: 2.5 volt, 170 ma, 0.42 watt, 1.13 lumens, soft core, which allows this bulb to be compatible with most lamp holder; These mini Christmas replacement light bulbs are bright enough and can use for a long time, designed for the light set with a multiple of 50 lights, but don't exceed 300 light - Replacement supplies: our products are suitable for Christmas tree decoration replacement, ideal items for replacing bulbs which have burn out or applied for a long time - Bulb type: ultra-bright incandescent (will glow dim in energy saver light set), can fit your Christmas trees lights better, working as it does, you just need to take off the unnecessary ones and replace them for the new ones, easy to assemble - Warming tips: these replacement bulbs are designed without being tapered slotted or pinched at the bulbs' bottoms, 2 wires only; When you replace the bulb, you must be careful to make sure the wire do not cross when you put back into the base, if the wire is crossed, it could cause them to short and "burn" out ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YFBR3BZ | | Additional Features | / | | Best Sellers Rank | #15,842 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #172 in Incandescent Bulbs #258 in Indoor String Lights | | Brand | Mudder | | Brand Name | Mudder | | Brightness | 1.13 Lumen | | Bulb Base | E26 | | Bulb Shape Size | E17 | | Color Rendering Index | 80 | | Color Temperature | 6000 Kelvin | | Connectivity Technology | Normal bulb | | Control Method | App | | Controller Type | Push Button | | Customer Reviews | 4.4 out of 5 stars 4,802 Reviews | | Efficiency | Standard Efficiency | | Incandescent Equivalent Wattage | 0.42 Watts | | Included Components | 100 Pcs Mini Christmas Replacement Light Bulbs | | Indoor Outdoor Usage | Indoor | | Item Dimensions W x H | 2.76"W x 0.63"H | | Item Weight | 2.39 Ounces | | Light Color | Clear | | Light Source Type | Incandescent | | Light Source Wattage | 0.42 Watts | | Light Type | Incandescent | | Manufacturer | Mudder | | Material Type | Plastic | | Model Number | B07YFBR3BZ | | Number of Items | 100 | | Package Quantity | 100 | | Power Consumption | 0.42 Watts | | Power Source | Corded Electric | | Shape | Tubular(T) | | Special Feature | / | | Specific Uses For Product | Indoor | | Theme | / | | Unit Count | 100.0 Count | | Voltage | 2.5 Volts | | White Brightness | 1 Lumens | ## Product Details - **Brand:** Mudder - **Bulb Base:** E26 - **Bulb Shape Size:** E17 - **Light Type:** Incandescent - **Special Feature:** / ## Images ![100 Pcs Mini Christmas 2.5 Volt Replacement Light Bulbs for Christmas Trees Decorative Light Supplies Indoor Outdoor Xmas Decor, 0.17 Ampere, 0.42 Watt (Clear) - Image 1](https://m.media-amazon.com/images/I/81kttKukelL.jpg) ## Available Options This product comes in different **Color, Item Package Quantity** options. ## Questions & Answers **Q: 2.5 volt 0.43 watt needing to replace burnouts on my Christmas tree. Will these suffice?** A: Please kindly know that there are two kinds of bulbs at 2.5V. One is the .25 Watt, 100mA, "ES" bulb. The other is the .42 watt, 170mA "SB" variety. "ES" draws less power so they can still use the same wire size and power LOTS of bulbs, like the 300 light sets, icicle sets, and so on. If you don't know the wattage, current, or SB/ES rating of the 2.5 Volt bulbs, you have a 50%-50% chance of having the wrong bulb: getting a very dim bulb (SB bulb in an ES socket) or a quickly burned out bulb (ES bulb in an SB socket). Please know this before you buy. **Q: Will it fit Balsam Hill "lamp lock" trees?** A: These will most likely fit your tree. You can remove the bulb from the green plastic "lamp lock" base, and replace it with this bulb. **Q: Is the filament sticking out the bottom of the bulb extra long 1s i have need it long** A: Not sure if they qualify as extra long, but they work in my patio lights. With a bit to spare. **Q: Will these replacement lights work on my tree, the label says esd-200/4f(0.4),120v, 60hz, 0.4a,48w, 09/09. 2.5vol, 0.25watt lamps. will these work?** A: these bulbs are made for "mini-xmas" 50 light SETS. Each 2.5 volt bulb is in series and add up to the 125 volt "normal" house supply voltage. They are rated for a series current of 170 milliamps (.17A) so each bulb is 2.5V x .17A = .425 Watts. so each 50 lite string uses 20 watts connected to house outlet. The site's DESCRIPTION section is correct , NOT the TOP part of page. Sorry for long blurb, but for average use : these bulbs are for 50 light SETS ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good replacement lights *by M***S on March 9, 2026* Needed to replace most of my Christmas tree light bulbs and this kit was perfect it took me a bit of time to change them but they work great, easy to use, good price and they all worked and fit nicely ### ⭐⭐⭐⭐⭐ Cheap & Effective (+ Tips for Finding Burnt Bulbs) *by D***I on January 16, 2026* These were compatible with my old pre-lit National Tree with clear incandescent lights.
