Nightlight Bulbs Christmas Tree Decorations

This bubble night light is mostly used to decorate Christmas trees or customize other patterned lampshades for decoration.

 Bubble lamps, also known as lava lamps or liquid motion lamps, work on the principles of heat, density and convection. This is how they usually work:

A bubble lamp consists of a glass container filled with liquid, usually a mixture of water and a special type of oil. 

There are small sparkles inside the liquid. At the base of the lamp there is a heating element, usually an incandescent bulb or heating coil. 

When the night light is turned on, the heat source heats the liquid in the base. When the liquid at the bottom of the lamp heats up,

 the liquid will flow and tumble, producing a small amount of bubbles, but will not boil. 

The up and down flow of the liquid and the rise of the bubbles will drive the glitter inside to create a beautiful scene. 

As long as the night light is working, this active state will not disappear.

Traditional bubble lights with incandescent bulbs typically have a lifespan of about 1,000 to 2,000 hours.

On the other hand, LED bulbs last longer compared to incandescent bulbs.

LED bulbs are known for their durability, lasting anywhere from 20,000 to 50,000 hours or more, depending on the quality of the LED and how it's used.
