A warehouse in Sweden required an update to its existing lighting system. The original installation used high-wattage metal halide fixtures in a large storage space. The replacement project changed the lighting arrangement to adjustable LockLock LED tri-proof lights, creating a cleaner and more consistent illuminated environment for storage, movement and daily warehouse work.

Before the replacement, the warehouse relied on 16 metal halide lights rated at 400W each. The original installation was photographed before the new fixtures were installed. The image shows an older warehouse interior with the existing luminaires mounted below an insulated roof structure and a lighting environment affected by the age and condition of the space.

Before replacement: existing warehouse lighting with 400W metal halide fixtures
The project replaced the original 16-fixture arrangement with 12 adjustable LockLock LED tri-proof lights rated at 50W each. This change reduced the number of fixtures while introducing a purpose-built linear waterproof luminaire for a warehouse environment. The adjustable configuration allowed the installer to direct the light more effectively along the usable floor area and storage routes.
The selected product is the LockLock Series LED tri-proof light. Its waterproof, dust-resistant and impact-resistant construction is intended for demanding areas such as warehouses, storage spaces, workshops and other industrial environments. The final lighting result should always be reviewed against the site layout, mounting height, work activity and local lighting requirements.

The after-installation images show the updated warehouse with the new linear LED fixtures distributed across the ceiling structure. The luminaires create a more regular rhythm of light across the length of the building, while the open floor area remains visible for storage and handling activities. The documented measurement for this case is 130 lux at 1 m above the floor.

After installation: improved visual coverage across the storage and handling area
The LockLock Series was suitable for this replacement because the project required a linear fixture that could operate in a warehouse environment and provide consistent light across a long storage space. A tri-proof construction is useful where luminaires may be exposed to dust, moisture, vibration or regular cleaning. The adjustable design also supports more deliberate aiming than a fixed, purely decorative linear fitting.
The project demonstrates an important lighting principle: fixture quantity and wattage should be selected together with the building dimensions and mounting arrangement. A replacement should not be based only on the wattage of the old lamps. The installer and lighting supplier should review the floor plan, ceiling height, existing cable positions, storage layout and required illuminance before confirming the final configuration.
The Sweden warehouse moved from 16 x 400W metal halide fixtures to 12 x 50W adjustable LockLock LED tri-proof lights. The supplied project record documents a 130 lux result at 1 m above floor level, while the after photographs show the completed installation and the new linear lighting arrangement. The case provides a practical example of how a warehouse can combine a lower-wattage LED fixture family with a more organized ceiling layout.
The project record does not include a verified energy-consumption comparison, payback calculation, installation date or full photometric report. Those values should be calculated separately when preparing a formal ROI or compliance document.
For a comparable project, the supplier should receive the building length and width, ceiling height, mounting positions, storage-rack arrangement, operating schedule, required lux level, preferred colour temperature, emergency-lighting needs and control requirements. A lighting simulation can then confirm fixture quantity, mounting position, aiming angle and expected uniformity before installation.
For broader industrial applications, review the warehouse and manufacturing lighting solutions and share the project plan with the engineering team.

The Sweden warehouse replacement shows how an older high-wattage metal halide installation can be updated with adjustable LED tri-proof lights designed for industrial environments. In this 16 m by 40 m storage space, 16 x 400W metal halide fixtures were replaced with 12 x 50W LockLock lights, and the supplied record reports 130 lux at 1 m above the floor. The after-installation photographs show the resulting linear lighting layout across the warehouse. For each new project, the final fixture selection should be confirmed through a site-specific lighting calculation.
