This salt lamp bulb replacement guide has exactly what you need to know to choose the right light bulbs for different sized salt rock lamps.

It covers whether you should use 15-watt, 25 or 40-watt bulbs, the correct sockets and shapes and the 3 best salt lamp light bulbs depending on the size of your lamp.

Also ahead, detailed instructions on how to safely change blown bulbs and get your Himalayan salt lamp radiating a beautiful glow again in no time.

Why Salt Lamps Need Light Bulbs

A real Himalayan salt lamp requires heat from the light bulb inside it to work properly. This is why it’s recommended to keep them switched on at all times.

Importantly, low heat LED light bulbs should never be used inside salt rock lamps. They don’t work.

Salt lamps are hygroscopic, meaning they attract microscopic water vapor from the surrounding air. A special heat-producing bulb like this then warms up the salt crystals and evaporates away the moisture.

Your salt lamp should feel warm to touch and not be wet with moisture. If it is, then the light bulb needs replacement with a stronger wattage bulb.

What Bulbs Do Salt Rock Lamps Use?

Salt lamps require incandescent light bulbs that produce heat. 15-watt bulbs are most commonly used, but 25-watt and even 40-watt bulbs are better suited for larger lamps.

A E12 candelabra bulb with a screw in socket, also known as C7, is used in the vast majority of pink salt lamps sold in America.

People often ask: “What wattage bulb can I use in a salt lamp?”. It depends on the size of the lamp.

  • For small salt lamps up to 10 pounds use a 15-watt light bulb.
  • For medium salt lamps 11 – 20 pounds use a 25-watt light bulb.
  • For large salt lamps over 21 pounds use a 40-watt light bulb.

If you live in a very humid climate and your salt rock lamp is dripping water, even when switched on all day, you need a replacement bulb with a higher wattage.

The Best Himalayan Salt Lamp Light Bulbs to Buy

There are a few important factors to look for when buying replacement bulbs for salt lamps:

  1. Make sure they have a E12 candelabra bulb socket (unless your lamp instructions clearly say that it is one of the rare models that uses a different light fitting).
  2. Light bulbs for salt lamps should be thin, not wide. C7 torpedo or tubular designs are preferable to wide bulbs that may touch the salt, attract moisture and short out the electrical fitting.
  3. Check they are made by a reputable company with good customer ratings. Cheap salt rock lamp bulbs that keep on blowing are false economy. Long-lasting light bulbs save you money in the long run.

25-Watt Bulb Replacement

25-watt light bulbs will be significantly brighter than 15-watt ones and they are best in larger salt lamps well over 10 pounds.

40-Watt and 60-Watt Salt Rock Lamp Replacement Bulbs

Bigger Himalayan salt lamps require stronger bulbs to work properly and warm up the larger surface area of pink salt crystals.

Unfortunately, good 60-watt or 40-watt light bulbs for salt lamps are much harder to find. Negative reviews abound with many customer complaints about blown bulbs and overheating.

The best I’ve found is this great value E12 torpedo style 12 pack in warm white 40-watt and a full 2700K glow. There are also 60-watt salt lamp bulbs available on the same listing.

They’re a bit larger than the previous 15-watt and 25-watt bulbs at 1.26 inches by 3.5 inches so check your lamp has space. Generally though, big salt rock lamps over 20 pounds have a much larger hollowed out center.

90 day warranty, according to the seller, mercury-free and with 12 bulbs per pack they should last you for many years. This is the best choice for 40-watt Himalayan salt lamp bulbs.

How to Replace a Salt Lamp Bulb

When you buy a high quality salt lamp, like one of these beautiful fair trade designs, it should come with detailed instructions for how to change the bulb inside your lamp.

If it doesn’t, then try one of these 2 methods to replace the bulb inside your salt rock lamp. In all cases, make sure the light fitting cord is switched off and unplugged first.

Method 1

  1. Gently check if the salt crystal base can be rotated and removed while upright. With some popular brands, like WBM Himalayan Glow, you can simply rotate the wooden base and lift it up off the light fitting.
  2. Place the salt crystal on a protected surface and unscrew the old light bulb counterclockwise to remove it. Fit the new salt rock light bulb by screwing it in clockwise.
  3. Check it works by switching it on and off then carefully replace the salt crystal over the top of the light fitting and rotate the base back into place.

Method 2

  1. Salt lamp light bulb replacement in most models requires placing your lamp on its side on a protected surface first.
  2. Next see if you can gently pull out the light fitting from the base. Often there are two metal prongs that you can squeeze together to remove the light fitting.
  3. Some models may have the light fitting screwed into the base. In this case unscrew the outer screws, but not the center one.
  4. Once detached, pull the light bulb fitting out slowly to avoid breaking it. Then remove the blown bulb by turning it counterclockwise.
  5. Fit the new salt lamp bulb by screwing it in clockwise and check it works by turning the light on and off. Now you can reinsert the light fitting into your salt lamp and it will be as good as new.

The Right Bulb for the Right Lamp

Using high-quality replacement salt lamp bulbs, like these recommended ones, saves you time and money in the long run.

Remember that the light bulb size should be small and thin for salt lamps, have an E12 candelabra socket and be proper heat-producing bulbs to work effectively, not low heat LEDs.

Lastly, and importantly, use 15-watt salt lamp bulbs for small salt lamps up to 10 pounds, 25-watt for 11 – 20 pounds and 40-watt replacement bulbs for Himalayan salt lamps over 21 pounds.

The original bulb lasted a whole year, then burned out one evening when turning it on. I replaced it with another”night light” bulb, & it won’t light up! I checked the bulb in another device & it works, however the package it came in does not say “dimmable”—-could that be the problem? Do I have to buy a dimmable bulb?


Hi Sally,

Sounds like the night light bulb was unsuitable for your lamp’s fitting. As long it’s a E12 candelabra bulb socket the GoodBulb Himalayan Dimmable Salt Lamp Light Bulbs linked in the article should work well and is inexpensive for a 6 pack.

All the best,
