URA21PLUS Emergency Light 350 Lumens 1H

The Legrand URA21 LED PLUS 661607PL emergency light is an autonomous LED luminaire designed to provide safety lighting when a power outage occurs. It delivers a luminous flux of 350 lumens for 1 hour and can be configured for maintained or non-maintained operation depending on the wiring used.

With IP42 and IK07 protection, a rechargeable nickel-cadmium battery and a compact design, it is especially suitable for evacuation routes, corridors, stairways, exits and common areas in buildings where emergency lighting is required.

URA21 LED PLUS 350-lumen emergency light

Reference 661607PL belongs to Legrand’s URA21 LED PLUS range. In an emergency situation, it provides a nominal luminous flux of 350 lumens and maintains lighting for a 1-hour autonomy.

This capacity makes it possible to temporarily illuminate routes and safety areas when the building’s normal lighting fails, helping people find exits and evacuation routes.

Maintained or non-maintained operation

One of the main advantages of this luminaire is that it can be used in both maintained and non-maintained mode, depending on the wiring carried out during installation.

• Maintained operation: the light source remains on while mains power is available and continues to operate on battery power in the event of an electrical failure.
• Non-maintained operation: the emergency light remains off during normal operation and switches on automatically when the supply fails.

This dual option makes it easy to adapt the same luminaire to different design criteria and emergency lighting needs.

350 lumens for 1 hour

The URA21 LED PLUS 661607PL offers a 350-lumen emergency luminous flux, providing suitable lighting capacity for evacuation routes and spaces where a higher light level is required than with lower-flux models.

The nominal autonomy is 1 hour, during which the integrated battery keeps the emergency lighting operational.

4 x 1-watt LED

The luminaire incorporates 4 x 1-watt LED light sources. The use of LED technology provides a compact, instant-start light source suitable for safety applications.

The unit features an opal diffuser that helps distribute the light produced by the LEDs evenly and promotes uniform illumination of the space.

Rechargeable nickel-cadmium battery

The Legrand 661607PL includes a rechargeable nickel-cadmium battery made up of 4 cells.

• Battery voltage: 4.8 volts.
• Capacity: 1.5 ampere-hours.
• Technology: nickel-cadmium.
• Number of cells: 4.

The battery remains charged while electrical power is available and supplies the energy needed by the LEDs when a mains failure occurs.

230-volt power supply

The luminaire is designed to operate with a nominal 230-volt AC supply and a frequency of 50 or 60 hertz.

Power is connected through the terminals integrated into the base of the luminaire, making wiring easier during installation work.

Automatic terminals for quick installation

The URA21 LED PLUS range includes automatic terminals fixed to the base, simplifying electrical wiring and making installation easier.

The terminals allow connection of up to 2 conductors of 2.5 square millimetres, both for the power supply and for remote control connections.

This configuration also allows through-wiring when several luminaires are part of the same emergency lighting circuit.

4 cable entries

The design includes 4 cable entries to facilitate the arrival of electrical conduits from different directions.

It has an open rectangular entry at the rear and three knock-out entries located on the sides and at the top, suitable for conduits of up to approximately 20 millimetres in diameter.

IP42 protection

The Legrand URA21 LED PLUS 661607PL has an IP42 protection rating, so it is mainly intended for indoor installations within the environmental conditions specified by the manufacturer.

The range also offers specific accessories for installations that require different mounting configurations or higher protection.

IK07 impact resistance

The luminaire has IK07 mechanical resistance, providing protection against accidental impacts during use.

This feature is especially important in common areas, corridors and other circulation spaces where installed equipment may be more exposed to knocks.

Class II electrical protection

The URA21 LED PLUS is classified as Class II protection against electric shock, incorporating the insulation measures corresponding to this category.

Green LED charge indicator

The luminaire includes a green LED charge indicator that allows you to visually check that the unit is powered and that the battery system is operating under normal conditions.

This indication makes periodic emergency lighting inspections easier.

Standby mode via remote control

The Legrand 661607PL features remote-control terminals for remote standby mode. This function allows the status of the luminaires to be managed from a compatible device in the installation.

Standby mode is especially useful when the power supply to an unoccupied building is intentionally switched off, as it helps avoid unnecessary discharge of the emergency batteries.

Surface-mounted or recessed installation

The luminaire can be installed directly on the surface. Legrand also offers the URA21 LED PLUS recessed frame reference 661720PL, which allows the luminaire to be integrated into a false ceiling.

This option provides flexibility to adapt the installation to both technical requirements and the aesthetic finish of the space.

Compatible with the fixing points of the previous URA21LED range

The URA21 LED PLUS range retains the fixing points of the previous URA21LED range. This compatibility makes it easier to replace existing units during renovation or maintenance work.

Legrand also offers the traditional diffuser reference 661721 to adapt the appearance of the luminaire when required by the installation.

Compact dimensions

Reference 661607PL has a compact format that makes it easy to integrate into walls and ceilings:

• Length: 210 millimetres.
• Width: 110 millimetres.
• Depth: 41 millimetres.
• Color: white.
• Housing material: plastic.
• Diffuser: opal plastic.

Its reduced depth allows for a discreet profile once installed.

For evacuation routes and escape paths

The luminaire is intended for evacuation route lighting and signage. It can be installed in corridors, stairways, lobbies, access points, exits and other areas where lighting must be maintained during a power outage.

The sizing and distribution of the luminaires should be carried out in accordance with the characteristics of the space and the regulations applicable to the project.

Certified for emergency lighting

The Legrand 661607PL has AENOR certification. The certification documentation confirms its main features, including 350 lumens, 1-hour autonomy, maintained operation with the option of non-maintained configuration, the nickel-cadmium battery and the IP42 and IK07 protection ratings.

The range has been developed in accordance with the requirements applicable to emergency lighting luminaires.
