Comparison Summary
| Feature | 6V Board | 12V Board |
|---|---|---|
| Battery Type | 6V | 12V |
| Input Supply | Up to 12V AC | Up to 15V AC |
| Charging Current | Up to 500 mA | Up to 500 mA |
| Best Use | Small backup lights | Larger lighting systems |
Final Conclusion
- Choose 6V board for small, low-power emergency lighting systems
- Choose 12V board for larger setups requiring higher voltage and flexibility
The main difference is battery voltage and system scale. Both boards offer automatic charging and simple operation, but the choice depends on your battery setup and lighting requirement.
Frequently Asked Questions (FAQ)
1. What does an emergency light board do?
An emergency light board automatically charges a battery and powers LEDs during a power failure, providing backup lighting.
2. What is the difference between 6V and 12V emergency light boards?
The main difference is the battery voltage. 6V boards are used for small systems, while 12V boards are suitable for larger lighting setups.
3. Do these boards include battery and LEDs?
No. These boards require external connection of battery, transformer, and LED load.
4. What type of battery can be used?
You should use a battery matching the board rating (6V or 12V), typically lead-acid or sealed lead-acid batteries.
5. How does automatic charging work?
The board charges the battery when AC power is available and switches to battery output when power fails.
6. What transformer is required?
A step-down transformer (typically 12V AC or up to 15V AC depending on board) is required to power and charge the battery.
7. Can these boards be used for DIY emergency lights?
Yes. They are designed for DIY emergency lighting and backup light systems.
8. What affects backup time?
Backup time depends on battery capacity, LED load, and overall system efficiency.
