Solar LED Rechargeable Emergency Light

This is a 48 Led solar / AC rechargeable emergency light. Fully recharged battery works 9 hrs with 24 led’s and 4.5 hrs with 48 led’s. A SPDT switch is used to select 24 and 48 led’s. Deep discharge warning before 10 minutes of actual deep discharge is incorporated. Generally many emergency lights deep discharge cut-off stops suddenly. We don’t know when it stops. That is why I made my circuit to beep at low voltage for 10 mins so that we can aware before stopping suddenly. We have to switch OFF manually after beeping within 10 mins. I used Solar panel for charging which is renewable energy.”
