Description
EM-40W: Reliable Full-Power LED Emergency Power Supply
The EM-40W emergency power kit is engineered to provide an uncompromising safety solution for critical indoor spaces. While most emergency modules significantly dim the light to save battery, the EM-40W is designed to drive the LED fixture at 100% of its original brightness. This ensures maximum visibility and safety during evacuations in large commercial or industrial facilities.
Features
- 100% Full Power Output: Unlike standard emergency kits that reduce brightness to 10-30%, the EM-40W maintains 100% luminous flux, providing maximum visibility during critical power failures.
- Broad Compatibility: Specifically optimized for LED Tubes (T5/T8), LED Panels, and LED Linear Lights from 3W up to 4
- Ultra-Long Backup Time:Equipped with a professional-grade 11.1V 4000mAh 18650 Li-ion battery, supporting customizable emergency durations from 1 hour up to 6 hours.
- Simplified Installation:Designed for efficiency; simply connect the Live (L) and Neutral (N) wires of the LED light directly to the emergency driver terminals to enable emergency functionality.
- Intelligent Switching:The system allows for normal switch-controlled lighting when AC power is present and triggers instant emergency illumination the moment a power outage occurs.
- Industrial Grade Safety:Built with a Fireproof PC housing to ensure heat resistance and structural integrity in commercial environments.

EM- 40W Full-Power LED Emergency Power Supply RFQ:
Q1: What is the main advantage of the EM-40W’s “100% Full Power Output”?
A: Most emergency kits provide only 10-30% of the original light output to prolong battery life. The EM-40W is designed for high-security environments where maximum visibility is required. It ensures your LED panel or tube remains at 100% brightness during a power failure, providing a much safer environment for evacuation.
Q2: Can this kit be installed in a standard LED tube or panel light?
A: Yes. The slim profile (only 25mm thickness) and wide output range (DC 220V) make it compatible with a vast array of LED fixtures, including T8 tubes, panel lights, downlights, and linear lights. It is a versatile choice for both new installations and retrofitting existing lights.
Q3: Is the battery safe for commercial buildings?
A: Absolutely. The kit uses fireproof PC material for the housing to prevent fire spread. Additionally, the 11.1V 4000mAh Li-ion 18650 battery is a reliable power source that meets modern safety standards for emergency duration, supporting up to 6 hours of runtime depending on the load.
