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 ### ⭐⭐⭐⭐⭐ Cheap & Effective (+ Tips for Finding Burnt Bulbs) *by on Reviewed in the United States January 16, 2026* 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. ### ⭐⭐⭐⭐⭐ Worked great for one string of lights - but not another! *by on Reviewed in the United States December 1, 2024* I have a 10' string of lights that I bought about 15 years ago. I kept the box and the voltage rating of the bulbs wasn't listed. I also have an 18' string of lights that I bought about 3 years ago and it said 2.5V bulb on the box. Both were made by Holiday Time. Both have 50 bulbs per segment: 120V/50 bulbs = 2.5 volts per bulb. I won't bore you with the lengthy troubleshooting I went through (FYI I'm a retired electrical engineer) but the conclusion is unmistakable: the Mudder 2.5V mini bulbs work great on the 10' string but on the 18' string, the new bulbs are dim. To take Mudder bulbs out of the picture, I took a good bulb from the 10' line and put it in the 18' line: dim bulb. I took a good bulb from the 18' line and put it into the 10' line and it blew out immediately. I see that in the summary of the critiques there were a few more positives than negatives but they were both pretty close to 50% which further substantiates the idea that there are at least 2 different kinds of lines from Holiday Time. I plan on calling their tech support to understand what the difference is and what kind of bulb I need for my 18' line. ### ⭐⭐⭐⭐⭐ Make sure these are correct voltage for your light string! *by on Reviewed in the United States December 12, 2024* I replaced all the lights in Sponge Bob with these and they seemed extra bright but I thought nothing of it. Then he stopped working after a couple of days and I noticed all the bulbs were blackened a bit due to high heat and four of the 29 bulbs were burned out. Turns out the tag on the plug specifies 3.5V, .56 watts for replacement bulbs and these are 2.5V, .42 watts. I left a 5 star review because all the bulbs worked when I got them but didn't use them for the correct application. ## Frequently Bought Together - Mudder 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) - Mudder 60 Count Replacement Christmas Tree Light Bulbs 2.5v 0.425 Watt Replacement Light Bulb Mini Incandescent Wire String Lights Decoration for Prelit Xmas Tree(Green Base with Warm White Bulb) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/162212256-mudder-100-pcs-xmas-replacement-bulb-2-5v-clear](https://www.desertcart.dk/products/162212256-mudder-100-pcs-xmas-replacement-bulb-2-5v-clear) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-09-08*
