IP66 / IK10Dimensions
1200 × 91 × 75 mmOperating principle
The integrated LED light source converts electrical energy into light, while the luminous efficacy of 140 lm/W allows a high light output to be achieved using 40 W of electrical power.
4000 K neutral white light is suitable for work and technical areas where clear visibility is important, while the frosted polycarbonate diffuser helps distribute the light more evenly and reduce direct glare.
What are the benefits of this 40 W luminaire?The luminaire combines high 140 lm/W efficiency, IP66 protection and IK10 mechanical resistance. This is particularly useful in warehouses, production workshops, service areas and technical rooms where energy efficiency, housing durability and long operating life are all important.
140 lm/W luminous efficacy
A luminous efficacy of 140 lm/W means that the luminaire is designed to deliver a high amount of light per watt of electrical power consumed. This is particularly relevant in facilities where lighting operates for many hours per day, such as warehouses, production, logistics and technical areas.
4000 K neutral white light
A 4000 K colour temperature produces neutral white light suitable for work, storage, production, technical and commercial areas. A CRI ≥83 provides good colour rendering of illuminated objects, surfaces and details.
IP66 and IK10 protection
IP66
The high protection rating provides complete protection against dust ingress and protection against powerful water jets. This is relevant in demanding production, warehouse, technical and other indoor environments where dust, moisture or periodic washing may occur.IK10
The high impact resistance rating provides increased protection against mechanical impacts and makes the luminaire more suitable for intensively used industrial and technical areas.Aluminium housing and frosted PC diffuser
The aluminium housing provides mechanical strength and helps dissipate heat generated by the LED components. The frosted PC (polycarbonate) diffuser is designed to distribute the light and reduce direct glare from the light source.

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.
