Emergency lighting in stairways

As indicated in the Low Voltage Electrotechnical Regulation, in its Complementary Technical Instruction 28, emergency lighting is that which must automatically come into operation when the general lighting fails or when its voltage drops to less than 70% of its nominal value, and it is called automatically with short cut-off times ≤ 0.5 seconds.WHAT IS ITS PURPOSE? The purpose of the emergency lighting is:

Generically in ITC-BT 28 some premises are identified which must always have emergency lighting.In order to provide adequate lighting the luminaires will meet the following conditions:

How much light does an emergency lamp provide?

Emergency lamp, provides high white illumination with a flux of 220 lumens x 6 hours in low intensity and 3 hours in high intensity.

How do I know if the emergency lights are working?


That is to say at what voltage the emergency light should turn on. The standard says it is at 60% of the nominal voltage (220volt), i.e. 132 volts.

How long should an emergency light last?

The important thing is that these luminaires must illuminate the areas according to the CTE and have an autonomy system of at least 1 hour.

Emergency lighting in warehouses

Generating sets are not part of an emergency lighting system, since the time it takes for them to come into operation in the event of an accident is longer than required by the standard. On the other hand, they are suitable for back-up lighting, which is that which allows the establishment’s activities to continue in the event of a failure in the normal service.

There are two minimum service times: one for general use establishments and the other for those in which people must re-enter after the emergency has been controlled, such as hotels, hospitals, etc. In the first case, the minimum service time is 1.5 hours, while for the second case, the minimum service time is three hours.

Since we have shown that the current legislation lacks certain criteria, mainly because it suffers from an anachronistic obsolescence that has not been solved, we will rely on the requirements of the standards to determine the minimum requirements that an emergency lighting project must meet. These requirements will be detailed below, highlighting the standard that demands them:

Installation of emergency lighting

Depending on their use, they can be divided into safety lighting, intended to ensure the safety of people evacuating an area or having to finish a potentially dangerous job before the end of the emergency lighting installation.

It consists of one or more lamps, an internal battery and various electrical components inside and a pilot light, usually red or green, which remains illuminated when the lamp is switched off, while it is switched off when the emergency lighting comes into operation due to a power failure in the normal lighting system. Some emergency lighting models are provided with a lamp test switch to test the functionality of the lamps. The battery capacity is calculated to ensure a certain autonomy of the luminaire, ensuring the operation of the device for a certain time.

What color is the backlight?

The lights projecting forward shall be white or yellow and those projecting rearward shall be red, with the exception of the reversing lights, which shall be white, and the rear turning lights, which may be red or yellow.

What are the dipped headlights?

How many emergency lights per m2

It is becoming more and more common to see in buildings, especially large and modern ones, special lamps located at specific points (usually entrances and exits). These are emergency lights, designed to be switched on in the event of a power failure.

As a minimum, emergency lights should be located at all doors along the evacuation route, at stairways (so that each flight of stairs has emergency lighting) and at changes of level, direction or corridor intersections.

The regulations do not specify a type of luminaire, i.e. any luminaire can be used as an emergency light. However, it must comply with the illuminance requirements of the CTE. In other words, it would be indifferent to use as emergency light a system composed of LED, halogen or energy-saving bulbs.
