The reason is that our emergency output is one way of high frequency pulse, the output of pulse waveform  is  not completed but only half of that. But it will not  affect  the  functionality  of  fluorescent  tube  because  of  the  emergency running  is  not  frequent.  Unless  emergency  back  up  functionality is needed all  the  time  that  will  impact  the  life of tube slightly.
Yes, all of our LED emergency modules are designed, developed and manufactuered by our own engineers and workers. Our professional experienced engineers can provide specific solution to your unique projects.
We are a factory, we provide OEM services and accept small order. We only focus on the manufacturing of  products-Emergency Conversion Kits.
We as a factory focus on designing, producing and selling emergency battery backup power pack for LED lightings. Our main products are:
  1. Constant current output LED emergency driver and battery pack conversion kit for LED panel light, LED ceiling light, LED
  2. 100% full power output of emergency battery pack kit for LED tube at AC100-270V or DC100-277V.
  3. Constant voltage output led emergency conversion kit for LED Strip light.
  4. LED emergency power inverter kit for unique installation environment like: waterproof led emergency conversion box,  Anti-explosion emergency conversion box, High temperature Ni-Cd, Ni-MH and Li-ion rechargeable battery pack for emergency control gear.
Our markets mainly spread over Europe, South of America, Africa and Asian Pacific region as well as domestic marketing, we have 8 years of experience in foreign trade, we have worked with buyers of lighting importers and distributors etc.
For Nicd battery we offered you, we set up the charging current at 0.05C(1/20 battery capacity) that is suitable for long time constant charging, no any damage for battery. It’s characteristics of NiCD itself.
Normally 2 years later. For Nicd battery, the capacity will be reduced by 10% at first of year and 20%of the second year, it will remain 70%-80% after total 3 years.
No, The battery is being charged all the time, The charging current will be decreased based on the  capacity status during the charging process. For NiCD and NiMH battery, it is applicable for constantly charging  without any risk even though no over voltage protection. But  under voltage protection is set up for discharging.
The main difference is that high temperature battery can be trickle charged well even though the emergency power kit stay at high temperature due to insufficient radiating caused by the lights working for long time, while normal temperature battery may stop charging in such conditions that result in emergency light failed to work. We would highly recommend to use high temperature battery for emergency lighting kit.
NO The emergency output is high voltage and high frequency (1000v 230KZ))for fluorescent,That is not applicable for LED system.
No. It must be confirmed with us case by case.
No, The battery pack of emergency conversion kit must be charged over 24 hours before discharging.
