Is this the classic 20 oz. Lava Lamp size?

Yes. It is the 20 oz. classic size, 14.5 inches tall, with a 4-inch base footprint.

What bulb does it use?

A 25-watt bulb, which is included. It plugs into a standard 120-volt outlet and has an on/off switch.

Why is the liquid cloudy?

Cloudiness is common after shipping, when the wax splits into tiny particles. A troubleshooting guide is included, and warm-up cycles usually clear it.

How long does it take to start flowing?

Expect a warm-up period after switching it on before the wax rises and splits; the motion builds as the bulb heats the globe.

Is it safe to leave on?

It is UL tested and certified, but the globe and bulb get hot, so keep it on a stable surface away from curtains and other flammable items.

How does it compare with larger Lava lamps?

The 20 oz. is smaller and lighter with smaller wax blobs; the larger 32 oz. and 52 oz. models show bigger, slower shapes but take more space.

About the Lava Lamp Black and Purple

This is the classic 20 oz. Lava lamp, standing 14.5 inches tall. Black wax floats in purple liquid inside a glass globe. The base and cap are silver aluminum, and they are hand-spun.

When the lamp warms up, the wax forms blobs of different sizes. They collide, split apart and rise and sink around the globe. The lamp gives off a soft, warm light.

It plugs into a standard 120-volt household outlet and has an on/off switch. It is UL Tested and Certified. A 25 watt bulb is included.
