Noticing bubbles in the wax of your Vanful lava lamp? You're not the only one. Based on our research, this happens for a few reasons linked to how these lamps work.
First, give it some time to warm up. These lamps use heated wax to create that cool lava-like motion, but they take a little while to hit the right temperature. At the start, as the wax melts, it's not as fluid, which can cause bubbles. Usually, if you let the lamp warm up completely—about 2 to 3 hours—it sorts itself out and you get those smoother flows without too many bubbles.
Sometimes, it's how the lamp is made. It's not uncommon to find small bubbles right when you take it out of the box. This might be air trapped in the wax during production. While you might see this affect the initial flow, most folks say it's not a big deal in the long run.
Where your lamp sits can also contribute. Places with big temperature changes or high elevations can affect how the wax behaves. So if there's a lot of temperature swings where you live, your lamp might act a bit differently too, especially when it's heating up and cooling down.
To help with the bubbles and keep your lamp looking good, try to place it in an area with stable temperatures and let it warm up fully before checking if everything's running smoothly. If bubbles stick around even after it's been on for a while, it might be a defect, and reaching out to customer service for a replacement could be wise.
In a nutshell, bubbles are pretty normal and usually calm down once the lamp's up to full temperature. Enjoy the vibe your lamp creates, and if you have any long-term concerns, don't hesitate to contact the manufacturer.
