Common DUAL-LITE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DUAL-LITE equipment arriving at our workshop.
- ✓LED driver circuit failure — no emergency light output — Dual-Lite LED drivers use high-frequency switching topology vulnerable to capacitor drying and FET gate oxide breakdown, especially in high-ambient-temperature Indian industrial environments. Switching frequency oscillations cause output collapse.
- ✓Battery charger not detecting or charging backup battery — Dual-Lite charger modules use thermistor-based battery temperature sensing and voltage divider networks prone to corrosion in humid environments. Sensor open-circuit or charging MOSFET failure prevents trickle and fast charge modes.
- ✓Emergency light dims erratically or flickers during normal operation — PWM dimming circuits in Dual-Lite luminaires suffer from frequency drift when feedback capacitors age or control IC timing pins oscillate. Mains voltage fluctuations common in Indian power grids aggravate instability.
- ✓Battery backup time drastically reduced — lights extinguish prematurely — Dual-Lite emergency systems fail to sustain load due to battery internal resistance increase, charger voltage regulation loss, or LED load circuit presenting short-circuit conditions to the inverter. Lithium cells degrade faster in uncontrolled Indian warehouse conditions.
- ✓Self-test relay sticks or test cycle never completes — Dual-Lite test panel microcontrollers issue relay energize commands but mechanical relay contacts fail to release, or firmware watchdog timeout occurs if test timing IC lags. Relay coil resistance rise causes under-voltage drop-out failure.
- ✓Exit sign remains fully illuminated even when mains power is cut — Dual-Lite exit control boards use power-down relay or soft-latching FET circuit to isolate battery from sign during normal operation. Relay contact welding or FET gate drive IC failure causes continuous energization from backup battery, draining reserve power.

Frequently Asked Questions — DUAL-LITE Repairs
Do you repair Dual-Lite emergency lighting equipment anywhere in India?+
Yes. Synchronics Electronics offers pan-India Dual-Lite repair coverage — we service LED emergency luminaires, battery backup modules, exit sign controls, and test panels from Mumbai, Delhi, Pune, Hyderabad, Chennai, Ahmedabad, Bangalore, and all other Indian cities. Free pickup and delivery within 48 hours. All repairs completed in our Vadodara, Gujarat facility by certified technicians with 15+ years Dual-Lite experience.
How do you diagnose Dual-Lite LED driver failures without factory schematics?+
Synchronics reverse-engineers Dual-Lite LED driver PCBs using non-destructive curve-tracing, oscilloscope analysis of switching waveforms, and component-level testing. We identify failed MOSFETs, boost converter inductors, and feedback networks without schematics. Our laboratory has verified spares database for 95% of Dual-Lite luminaire generations in use across India.
What is the typical repair turnaround for Dual-Lite battery charger modules?+
Simple battery charger faults — capacitor replacement, thermistor reconnection — are completed within 24-48 hours. Complex inverter or boost converter repairs requiring EEPROM reprogramming or custom IC replacements take 5-7 working days. Synchronics provides daily repair status updates and charges only for parts tested and replaced. All repairs carry 12-month warranty.
Can Synchronics repair Dual-Lite equipment with corroded battery terminals and water ingress?+
Yes. Synchronics specializes in moisture-damaged Dual-Lite restoration — we desolder battery connectors, clean corrosion using ultrasonic bath, replace water-damaged capacitors, and apply conformal coating to prevent future degradation. Equipment exposed to humid conditions is humidity-cycled tested (0-95% RH) before release. Many Indian pharmaceutical and food plants trust us for wet-environment Dual-Lite repairs.
Do you stock Dual-Lite replacement parts or only repair existing units?+
Synchronics repairs and restores all Dual-Lite assemblies using original or verified equivalent components. We source Dual-Lite batteries, relays, microcontroller ICs, and LED driver modules from authorized distributors in India. For emergency situations, we offer expedited parts sourcing within 48-72 hours. Repair cost is typically 40-60% lower than replacement equipment.
How do I send my DUAL-LITE unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DUAL-LITE drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DUAL-LITE repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DUAL-LITE unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
