Types Of Emergency Lighting

Emergency lights come in various different types of lighting, this is because of the different types of critical power supplies. Sometimes it can be hard to differentiate them all. Below is an outline of the types of emergency lighting and also when you should get your emergency lighting tested.


  • Maintained Emergency Lighting – A maintained emergency light fitting will work on a standard lighting system, When installed it will connect to your existing lighting system and they will all work together. When there is a power shortage the lights will come at a lower light until the emergency electrician arrives.
  • Non Maintained Emergency Lighting – These types of lights will generally remain not in use, They will have a permanent power supply that is generally indicated by a LED light that shows its being charged. When the power goes, these lights will illuminate. They are generally used as exit signs.
  • Combined Emergency Lighting – The combined emergency lights has 2 power supplies, one will draw power for the normal lighting and the other will draw power for the emergency light. The emergency light can be maintained or non maintained.
  • Escape Emergency Lighting – The escape emergency lights will automatically power when the power cuts off, this lights will illuminate the escape route in case of an emergency.


Emergency Light Testing and Maintenance

Emergency lighting will require maintain and testing just like any other type of equipment, this is to ensure that they are in good working order and will work under fault or emergency conditions. Below is a general guide to your emergency light testing.


A monthly test can be quick and simple, it is not only a good idea but also good practice. A monthly test will verify that everything is working. The easiest way to undertake the test is by switching the power off by the emergency light switch if you have the key to it. If you don’t have the key you will have to isolate the power to that circuit which will generally be indicated on the consumer unit. Once isolated have walk round make sure the lights have come on and then turn the power back on. Once done you can then place a note in the log book.


This type of test is a little bit more intense and will require a outside source to undertake, you should have this type of test done every year and it should be carried out by a competent person. All the lights will be switched off for up to 3 hours to ensure they will work through a fire or an emergency


What important to consider when performing tests

When it comes to getting your emergency light test done, you may consider a few things outlined below

  1. What is your risk factor? If your area is within a space that employees or clients are in regular attendance. You may consider to have your testing done out of hours. The reason I suggest this, is because once the test has been completed, your system will be left vulnerable. The reason is because that when having a emergency light test conducted you have to drain the batteries. The batteries will require time to recharge, therefore   you will need time for your emergency lights to work in case of an emergency.
  2. Will the test be effective?, If the room that is being tested is very bright, it will be hard to say whether the lighting meets the requirements set out by the regulations. This is another reason why some companies opt to have it done in the evening.
  3. Lastly you may want to consider the convenience to your employees and customers, if they are in the building and you turn of the lights. Will this effect the way your staff work or your customers receive there service? Remember to take all these factors into consideration when doing your emergency light certificate.
