BX-D049 20W LED Emergency Power Supply with 90-Minute Battery Backup

20W LED emergency power supply BX-D049 is a compact battery-backup conversion module designed for commercial lighting manufacturers, electrical contractors, distributors and project buyers. It operates from AC220V and uses a built-in 3.7V lithium battery to provide approximately 90 minutes of emergency operation after mains power is interrupted. With a slim enclosure, clearly marked terminals and visible test and status indication, the module is practical for integration into compatible LED luminaires where a dependable emergency-lighting function is required.

Compact Emergency Conversion for B2B Applications

For luminaire producers and project contractors, an emergency power module must be easy to integrate, straightforward to inspect and supported by clear electrical information. BX-D049 brings the emergency electronics, lithium battery and operating-status area together in one compact enclosure. Its long, narrow body can be considered for compatible linear fixtures, battens, panels and other commercial lighting products where internal space is limited. The left-side terminal area is labelled for input, output and switch connections, while the right-side indication area identifies charge, test, fault and mains conditions.

When normal AC supply is available, the unit supports charging and monitoring of the internal battery system. If mains power is lost, it changes to emergency operation and delivers a catalog-specified emergency light output of at least 50 lumens for 1.5 hours. This reduced-output mode is intended to provide orientation and egress-support lighting rather than full normal-lighting output. The actual illuminated result depends on the connected LED load, driver configuration, luminaire optics, installation environment and final system design.

Technical Specifications

Typical Project Uses

The BX-D049 can be evaluated for compatible LED battens, linear luminaires, panel-light assemblies, selected downlights and custom emergency-lighting products used in offices, hotels, schools, retail spaces, corridors, stairways, warehouses and other commercial facilities. It is also suitable for OEM and ODM discussions where a lighting manufacturer needs a compact emergency function built into a new fixture design. Distributors may use the model as a project-specific emergency conversion option, subject to electrical compatibility and local requirements.

What Buyers Should Confirm Before Ordering

Emergency conversion equipment must be matched to the complete luminaire system. Before volume production or installation, please confirm the LED load characteristics, driver topology, input wiring, available mounting space, thermal conditions, charging arrangement and required emergency output. A sample evaluation is recommended before a bulk order. Final installation, wiring and periodic testing should be performed by qualified personnel in accordance with the applicable electrical and emergency-lighting rules in the destination market.

For B2B enquiries, send us your luminaire type, normal wattage, driver information, target emergency duration, required quantity and destination country. Our team can review the application, discuss compatibility and prepare an OEM quotation. Packaging, labeling and project documentation can also be discussed for distributor, contractor and luminaire-manufacturer orders.

OEM, Sampling and Quality-Control Support

For repeat purchasers, the emergency module can be discussed as part of a coordinated sourcing program rather than as an isolated component. Buyers may request pre-production samples for electrical verification, then confirm the bill of materials, labeling, packaging method and inspection standard before mass production. Incoming and production checks can cover enclosure condition, terminal security, charging indication, simulated mains-failure changeover and emergency operating time. Where the module is being built into a finished luminaire, the completed assembly should be tested again because LED characteristics, optical efficiency, ambient temperature and internal heat can influence final emergency performance.

Project quotations can be prepared for prototype quantities, distributor orders and scheduled production batches. If your market requires a particular test report, marking, plug, lead length or documentation package, provide the exact requirement at the enquiry stage so feasibility can be reviewed. The catalog specification describes the standard BX-D049 configuration; customized versions, compatibility statements and regulatory documentation must be confirmed in writing for the actual order. This approach gives lighting brands, contractors and importers a clearer path from sample validation to repeat supply.
