Motion activated security lights become active when the PIR (passive infrared) sensor detects movement meaning the light is only used when needed and saves energy. As well as a security feature, highlighting any intruders, it is also a safety feature to have a light which turns on when you are walking down a path or steps in the dark. Many of the security lights available have the ability to set the range that it can activate from and level of darkness it detects motion.

Solar security lights require no mains power or wiring as they generate their power from sunlight. These lights absorb the energy from the sun during the day by using rechargeable batteries. Once fully charged, these lights should give light for 10-12 hours. Because there is no mains power, these lights provide a cost effective and environmentally friendly lighting solution.

There are security lights that are programmed to activate at set times or only when it gets dark and stays illuminated until the morning using photocell, a system which can detect levels of light. This type of lighting system is the least cost effective option available particularly in the winter months when there are more hours of darkness.

Floodlights are the most common type of outdoor lighting typically used on the outside of houses, car parks and business premises. LED flood lights are cost effective as they use lower levels of energy than halogen flood lights. Halogen flood lights give off a bright white light and have mains and solar power options available.
