Review: 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.
Review: 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!

## 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

### ⭐⭐⭐⭐⭐ Good quality and worked perfectly.
*by A***R on January 4, 2026*

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.
