Can I use an LED or a brighter bulb instead of a Lava Lite bulb?
No: a 14.5 inch lamp is built around the heat of its 25 W incandescent bulb. An LED bulb gives light without the heat, so the wax never moves, and a brighter bulb overheats the globe.
| Compare | Lava Lite 25 W bulb | LED bulb | 40 W or brighter bulb |
|---|---|---|---|
| Heat for the wax | Matched to the 20 oz globe | Too little: the wax does not melt | Too much for a 20 oz globe |
| What the lamp does | Flows in 2 to 3 hours | Lights up but never flows | Overheats, with a risk of a cracked globe |
| Socket | E17, S11 shape | Must be E17 to fit at all | Our 40 W bulbs use the larger E26 socket |
| Rated life | 1,000 hours | Longer than incandescent | Varies by bulb |
| Energy | 25 W | A few watts for the same light | 40 W and up |
| Better choice when | The lamp is a 14.5 inch Lava Lite | It is for any other lamp in the house, where heat is waste | The lamp is a 16.3 or 17 inch model, which is built for 40 W |
LAVA® Lamps need both light and heat to function.

From buyers
What buyers say about the 25 W Bulbs, 2-Pack
Replacement Light Bulb seems to do the trick!
Overall, I would say this product is pretty good! I bought my lava lamp years ago, and the original light bulb had since burnt out. I searched around to find a decent light replacement, and I decided to try this one. It has been months, and the replacement light bulb still works! I don't use it every day (or even every week for that matter), but I've used it enough times to see that it is decent! I think the best part is the price per bulb, seeing that this is a two-pack.
Works 100% in 14.5" Lava Lamp
These bulbs are the absolute jam! The perfect S11 size for a 14.5" lava lamp - the bulb has plenty of heat to quickly melt the wax inside the lamp whereas other Chinese knock-off bulbs were not sufficiently hot to work. Spent a few more dollars and get the real deal like these bulbs and never look back.
Questions
Lava Lamp Replacement Bulbs: answers
How long does a Lava Lite bulb last?
A Lava Lite appliance bulb is rated for 1,000 hours. At 3 hours an evening that is about 11 months.
Is the 5025 bulb the same as a refrigerator bulb?
It is the same family: the Lava Lite 5025 is a 25 W incandescent appliance bulb with an E17 socket and an S11 shape. Match all three, not the wattage alone.
