LED weatherproof luminaire with emergency module | 1200 mm | 40 W | 140 lm/W | 5600 lm | 4000 K | IP66 | IK10 | 3 h
Professional 1.2 m LED weatherproof luminaire with an integrated emergency module, designed for warehouses, production areas, technical rooms, garages, corridors, logistics centres and other demanding applications. 40 W power, 140 lm/W luminous efficacy and 5600 lm luminous flux provide efficient general lighting, while in the event of a mains power failure the emergency module allows the luminaire to operate for up to 3 hours. IP66 protection, IK10 mechanical resistance and an aluminium housing are designed for demanding operating conditions.
Key pointThis model combines efficient 40 W general LED lighting and an emergency mode with up to 3 hours of operation in one housing. It is a practical solution for facilities where lighting must be maintained for safe movement, orientation or evacuation if the main power supply fails. IP66 and IK10 additionally increase suitability for demanding technical and industrial environments.
Power
40 WLuminous flux
5600 lmEfficiency
140 lm/WEmergency mode
up to 3 hOperating principle
In normal operation, the luminaire is powered from a 220–240 V AC mains supply and operates as the main 40 W LED light source. At an efficiency of 140 lm/W, the rated luminous flux reaches 5600 lm.
If the main power supply fails, the integrated emergency power module switches the luminaire to emergency mode. Emergency lighting operating time is up to 3 hours.
3-hour emergency mode
The integrated emergency module is designed to maintain lighting when the main power supply fails. Up to 3 hours of operation is particularly relevant in corridors, passageways, technical areas, warehouses, production facilities and other locations where orientation or safety lighting is required during a power outage.
ImportantA 3-hour emergency operating time does not mean that the full 5600 lm luminous flux of normal operating mode is maintained during emergency operation.
140 lm/W luminous efficacy
Luminous efficacy indicates how much luminous flux is produced from one watt of electrical power. In this case: 40 W × 140 lm/W = 5600 lm.
Lighting characteristics
4000 K
Neutral white light suitable for work, production, storage, technical and general-purpose areas.CRI ≥83
Good colour rendering for general professional, commercial and technical lighting.PF >0.95
High power factor, relevant for professional installations with multiple luminaires.IP66 protection
- IP6X – complete protection against dust ingress into the housing.
- IPX6 – protection against powerful water jets.
- Practical for dusty, humid and demanding technical environments.
- IP66 does not mean protection against continuous immersion in water.
- The housing and electrical connections must remain properly sealed during installation.
IK10 mechanical resistance
IK10 is a high mechanical impact resistance class. This is an important advantage in garages, parking areas, warehouses, production facilities, technical corridors and other areas where there is a greater risk of accidental mechanical impact.
Aluminium housing
The aluminium housing provides mechanical strength and helps dissipate heat generated by the LED components and electronics. This is important for stable and long-term operation of the luminaire.

Based on their quantity, you can choose a light fixture that will properly illuminate the entire room.
How to choose the right number of lumens in a light fixture?
450-800 Lm are used for decorative lighting, table lamps, bedside lamps. Light fixtures with up to 800 Lm brightness are suitable for creating a cozy environment.
800-1100 Lm are used for small rooms (bedrooms, hallways).
1100-1600 Lm are used for medium-sized spaces such as dining rooms, kitchens, bathrooms, and children's rooms.
1600-3000 Lm are used for large rooms (shopping malls, entire 11-18 square meter rooms).
Light fixtures with more than 3000 Lm emit very bright and intense light. They are used in workshops, garages, and industrial spaces.
To accurately calculate the required number of lumens for a room, use the formula:Lm = 150 lx * 4π * (distance in meters to the surface)²

3 main types of white light:
Warm white (2700 - 3000 K)
Neutral white / daylight (4000 - 4500 K)
Cool white (5000 - 6500 K)
How to choose the right light color temperature:2700 - 3000K creates a cozy atmosphere in a room. Used in spas, hotel entrances, living rooms, and bedrooms.
4000 - 4500K is used in commercial, retail, office spaces, garages, medical buildings, as well as bathrooms, kitchens, and workrooms.
