Emergency Lighting: How To Measure It With The LS-110

Emergency Lighting is an essential backup source used when a building or structure experiences a power outage. They are installed in virtually every commercial or high occupancy residential building. The light often consists of one or more clusters of high-intensity LEDs.

Emergency lighting is manufactured to the highest possible standard. They are subjected to various stringent quality control tests at the end of the production line as well as on-load multiple cycle life tests. Products are also subjected to tests to ensure compliance against standards.

Light Meters are used to quantify the contrast ratio between the alphabet and the background to ensure visibility when lighting is shut down due to power failure in a building or structure. The illuminated panel must emit a minimum requirement of light to ensure that exits and other light sources are easily located.

For this type of application, Konica Minolta offers the LS-110 Handheld Luminance Meter. This meter features an SLR (single lens reflex) optical system, which allows for precise targeting. This ensures that the viewfinder will show the exact area being measured, even at very short distances. Close up lenses are available to allow measurement of areas as small as 0.4mm in diameter. The narrow 1/3° measuring angle on the LS-110 enables measurements to be taken within the limited width of each letter on the emergency sign. The LS-110 is lightweight and compact, which makes on-site measurements quick and easy. It is powered by a single 9V battery.
