What Watt Bulb Do You Need?
Scentsy warmers are designed to work with specific wattages, and choosing the right one really matters. Mini plug-in warmers take 15 watts, smaller tabletop warmers usually use 20 watts, and most full-size warmers need 25 watts. If you’re not sure which one your warmer needs, check the bottom of the warmer for a label, dig out the original box or user guide, or look it up in the current catalog if it’s still available.

How to Replace a Scentsy Bulb
Replacing a Scentsy bulb is super simple. Just unplug your warmer, let it cool, swap out the old bulb, and screw in the new one that matches the correct wattage. No tools, no fuss. That’s it. You’ll be back to warm and cozy in no time.
Why Use a Scentsy Replacement Bulb?
You can use a different brand bulb…but should you? The short answer is yes, you can. The longer answer is a little more technical.
If you decide to use a different brand bulb, please make sure you stay with the correct wattage. Increasing the bulb wattage can possibly damage your warmer, as it’s designed to work with a lower wattage bulb for lower temperatures and safety. If you use a higher wattage bulb and it does damage your warmer, you’ve voided the famous Scentsy Lifetime Warranty.
Also, when you use the incorrect wattage, you run the risk of wasting your money. Too low of a wattage and your wax doesn’t melt. Then you buy a Scentsy bulb, and you’ve just wasted money on the off-brand one.
Too high of a wattage—and even if you don’t damage your warmer—you still shorten the time your fragrance lasts. Scentsy bars are developed for a low melting point. Anything hotter will cause the scent to evaporate faster.
So while yes, it’s technically possible to use another bulb, you’re playing fragrance roulette. Stick with Scentsy replacement bulbs to keep your experience safe, long-lasting, and hassle-free.
What Watt Bulb Do You Need for Your Scentsy Warmer?
Scentsy uses three types of bulbs: 15W, 20W, and 25W. The bulb your warmer needs depends on its design and size. Here’s a quick guide:
Bulb Wattage | Used For |
|---|---|
15 Watts | Mini Warmers (plug-ins) |
20 Watts | Smaller tabletop warmers |
25 Watts | Full-size warmers |

How Long Do Scentsy Bulbs Last?
It depends on how often your warmer is on, but from my own use, I can tell you this: if your warmer is going 24/7, the bulb can still last around a year or more. If you turn your mini warmers on and off daily, you’re looking at about 8 to 12 months. Oddly enough, keeping it on all the time might actually help it last longer—those filaments prefer consistency over being heated and cooled repeatedly. And if you want the light on without the fragrance, just pop the wax dish out. Easy fix.
Finding The Right Bulb Size
When you’re shopping, you’ll see options like the 15 watt Scentsy bulb, 20 watt, and 25 watt. These aren’t just different sizes—they’re designed for different warmer types. The 15 watt bulb is for plug-in mini warmers, the 20 watt works for some of the smaller tabletop warmers, and the 25 watt is for your full-size classics. These bulbs aren’t interchangeable, so it’s worth getting the right one the first time.
And yes, you can absolutely buy them in 3-packs. I always keep a few extras tucked away—you never know when a bulb will go out at the most inconvenient time (usually right before guests arrive, right?).
Not All Warmers Use Bulbs
Some Scentsy warmers don’t use bulbs at all. Element warmers have a hot plate instead of a bulb, and diffusers use LED lights built into the base that never need replacing. If those lights stop working, the diffuser base is usually still covered under warranty.
