Night lighting is a small, low-power electronic light source that provides comfort or convenience in an indoor area that dims at night.

Facts and data
Before they are energized, nightlights are usually long-burning candles placed in fireproof metal cups, known in some countries as tealights. (Tealights in the United States are very short and wide candles that can be purchased in aluminum tin cups commonly used in decorative glass clips. They are also known as candles.)
In the United States, approximately 90 million night lights are purchased each year. In 2001 alone, manufacturers recalled more than 600,000 products for safety reasons. Defective night lights can cause fire, burns and electric shock.




Night lights are usually installed to create a sense of security and reduce fear of darkness, especially for children. They also illuminate the overall layout of the room without causing eye strain caused by standard lighting and helping to prevent stairs or objects from tripping over. According to the American Home Care and Hospice Care Association, this is an important safety measure for the elderly, and for the elderly, falls are the leading cause of injury-related deaths. Night lights can also be used to mark emergency exits.

Types of

Homeowners can use a variety of nightlights; bulbs vary from incandescent to energy-saving options such as light-emitting diodes (LEDs), neon lights and electroluminescent bulbs. Some of these devices are equipped with a light-sensitive switch that is only needed when it is dark to start the light, saving power and the amount of work required to manually turn it on and off. Some designs also include rechargeable batteries, so they will continue to run during a power outage.

Night lights have the following dangers:

fire. According to the US Consumer Product Safety Commission (CPSC), nightlights can become overheated, causing them to melt and cause a fire when in contact with flammable materials. The US Consumer Product Safety Commission receives about 10 reports a year, which can cause fires when nightlights ignite toilet paper, pillows, bedspreads, and other flammable materials. In many of these cases, the night light is mounted very close to the bed, causing the blanket or pillow to come into contact with the night light and catch fire. Therefore, nightlights should not be inserted next to bedspreads, curtains and other objects and materials that may be flammable. InterNACHI inspectors can also ensure that nightlights are not covered by tape, cardboard or any other material that may cause overheating. Homeowners may consider using a night light with a mini neon bulb instead of a higher wattage bulb;

Poisoned. The so-called "bubble" night light is a special decorative night light that contains a dangerous chemical called methylene, which can cause unsafe attention for small children. If the vial ruptures, immediately throw away the device and take precautions. Chemicals that avoid skin contact with leakage; electric shock. Night lights can create a risk of electric shock when used outdoors or where it can get wet, such as near a sink or hot tub, or in a garage or covered patio. Never plug them into extension cords, surge protector strips, multiple exit strips or other removable types of sockets. If the night heats up and melts, an electric shock may occur.

LED Night Light Factory   provides tips for night light applications

Plug the night light into an exposed wall outlet and ventilate well.
Do not repair any night lights yourself. Only replace the lamp.
Avoid installing nightlights where they may be exposed to excessive sunlight, as UV rays can degrade plastics.
Never let the children handle the night lights. If you have children, avoid buying or installing night lights decorated with cute or funny characters, they may attract them and may be easily accessible.

In short, nightlights are used for comfort and safety, although homeowners should take precautions when purchasing and using these devices.
