Alrouf’s LED emergency ceiling light range includes four models with a rated 3-hour emergency duration, LiFePO4 batteries and maintained or non-maintained operation with switch control. Choose from 8W, 15W, 18W and 24W models, with emergency light output from 100 to 330 lumens.
The BY-Z3108E is rated IP54. The BY-Z1015E, BY-Z1018E and BY-Z1024E are rated IP65. Select the model according to the required emergency output, installation conditions and approved lighting design.
These emergency ceiling lights provide battery-backed illumination when the relevant normal lighting supply fails. They can be considered for corridors, staircases, offices and other building areas where their performance meets the project’s requirements.
The range includes BY-Z3108E, BY-Z1015E, BY-Z1018E and BY-Z1024E. Each model has different input power, normal light output, emergency output and battery voltage.
Use the model comparison below to review the differences before requesting a quotation.
During normal supply conditions, the charging system maintains the battery. The light source operates according to the selected operating mode and control arrangement.
When the relevant normal supply fails, the battery supports emergency illumination. Emergency-mode output is lower than normal-mode output, so lighting calculations must use the emergency luminous flux and relevant photometric data.
These models do not include automatic testing. Follow the manufacturer’s instructions and project requirements for testing and maintenance.

Start with the required emergency illumination, then compare the proposed models against the installation conditions.
Higher lumen output alone does not establish suitable spacing or mounting height. Coverage also depends on light distribution, room geometry, obstacles and the design criteria.
For a detailed selection checklist, read how to choose emergency ceiling lighting.
These luminaires may be considered for:
Confirm suitability for each location. An IP65 rating alone does not establish resistance to every outdoor condition, corrosion or hazardous atmosphere.
Before ordering, confirm the exact model’s dimensions, fixing arrangement, wiring instructions and maintenance clearances.
For Saudi projects, coordinate selection with the approved electrical and emergency lighting design. Request relevant technical documents and conformity evidence for the proposed model.
The brochure’s certification statements do not, by themselves, establish approval of the complete installation.
All four models have a rated emergency duration of 3 hours. Confirm installation and operating conditions against the manufacturer’s documentation.
No. BY-Z3108E is rated IP54. BY-Z1015E, BY-Z1018E and BY-Z1024E are rated IP65.
Normal output ranges from 500 to 1650 lumens. Emergency output ranges from 100 to 330 lumens. Use the selected model’s emergency output when assessing backup illumination.
All four models use 1500mAh LiFePO4 batteries. Battery voltage is 3.2V for BY-Z3108E, 6.4V for BY-Z1015E and 9.6V for BY-Z1018E and BY-Z1024E.
No. The brochure lists “No” for Auto Test on all four models. It lists a test switch and AC-ON indicator among the product features.
Yes. The brochure lists maintained and non-maintained operation with switch control. Confirm the required wiring arrangement before installation.
The brochure specifies a 24-hour recharge time for all four models.
