## Description

Commercial and industrial spaces need emergency lighting that can support clear routes when normal power is interrupted. The Qllite & Design SEMLW is a wall-mounted steel battery unit for that role, with adjustable dual LED heads and automatic activation during a power failure.

Its universal 120–347V input suits a range of building electrical systems. A minimum 120-minute battery backup helps keep emergency illumination available during an outage.

Each lamp head can be positioned independently, so light can be directed towards corridors, stairways, exit routes and other areas that need emergency coverage.

## Tech summary
- Type: Steel emergency light fixture
- Input: 120–347V AC
- Battery backup: Minimum 120 minutes
- Light sources: Two adjustable LED heads
- Total light output: 250 lumens
- Construction: 20-gauge steel housing
- Mounting: Wall mount
- Listing: cUL listed, tested to UL 924 and CSA C22.2 No. 141-15 requirements

The dual heads offer up to 360° of horizontal rotation and 180° of vertical adjustment. This makes it easier to aim illumination along a route or across more than one part of a space, rather than relying on a fixed beam direction. When AC power is lost, the fixture turns on automatically, providing emergency light without someone needing to operate a switch.

## Practical tips
Plan the wall position around the areas that need illumination, such as a hallway junction, stairwell or warehouse route, then aim each head to suit the layout. The fixture is designed for surface wall mounting and hardwiring, installation by a qualified electrician supports a safe connection to the building supply. Its 120–347V input accommodates common commercial and industrial systems within that range.

After initial hardwired installation, leave the unit connected to AC power for a full 24 hours before testing or carrying out routine safety inspections. This gives the battery time to charge before the backup function is checked. The fixture is rated for damp locations, making it suitable for commercial indoor areas where moisture may be present.

## In the box
The listed included component is the lamp heads. Together, the two adjustable LED heads form the fixture’s directional emergency-lighting arrangement, allowing the output to be set for the nearby path or area. The white steel housing provides a straightforward fit with commercial and industrial interiors.

## When it makes sense
Choose a dedicated steel battery unit when emergency illumination needs to be provided by a wall-mounted fixture with its own battery backup. Compared with an approach that depends on a separate emergency-lighting arrangement, this unit combines automatic response, two aimable light sources and a minimum 120-minute backup in one fixture. Its commercial-focused construction and broad input range also make it relevant to projects with different building supply requirements.

It makes sense if you need to direct light along a particular egress route or cover nearby areas from one wall position. For offices, corridors, stairways and warehouses, the independent head adjustment helps tailor where the 250-lumen output is directed, while the battery backup keeps emergency lighting available through a power interruption.
