Backup Time of the Emergency Light lamp.
Battery backup time of the emergency LED light Circuit
- Option 1 ( Full light) = 4-6 Hrs.
- Option 2 ( Normal Light) 10 Hrs.
Here is the full story that how did i make this post and share with you guys.
Actually, someone bring me a DP-716 Emergency LED Light lamp. So I took the lamp (for checking/repairing).
Here you can see the whole story in images.
Here, we have opened it for repairing. ( You can also try on such your home appliances, but keep in mind that safety is more important….)

Now it is clear that what is the real problem in pic ( two resistor were blown out) so now we want to fix it.
another view. check the circuit that what is the problem here.
Here you can see that what i did in this circuit. because the resistor on the back side ( which i have soldered) was blown out. so the root of problem was that specific resistor.
We have done the job. Now the pattern change switch is on Option 1 i.e. on Full light. the back up time will be 4-6 hours.
And in this case, the pattern change switch is on Option 3 i.e on Full light. the back up time will be 8-10 hours. also note that , option 2 is for turning off the Bulb light.
