DIY EMERGENCY LIGHT

HELLO GUYS IN THIS VIDEO I AM GOING TO SHOW YOU HOW TO MAKE A VERY SMALL,CHEAP AND COOL LOOKING POCKET SIZE EMERGENCY LIGHT

SO THIS EMERGENCY LIGHT IS WORK LIKE HELL ITS SO POWERFULL THAT ON EACH 9V BATTERY IT CAN GIVE UP TO 4 TO 5 HRS BATTERY LIFE SO WITHOUT FURTHER LETS DO THIS

Step 1: VIDEO

Step 2: Materials Required

8-1w leds

1-switch

1-battery clip

1-9v battery

small casing i used the small power supply casing

and basic tools

thats all it costs around 2$ to make it its that much cheap

Step 3: Hot Glue

hot glue every led on the casing like i did

Step 4: Heat Up the Soldering Iron

first coonect all leds positives together and all negatives together(parallel connection)

and then connect the positive of leds to one side of the switch and the other side of switch to the positive of the battery then connect the negative of the battery to the negative of the leds

and its done

if every thing is done perfecty then it will work like a charm

Step 5: Its Done

just close the casing and its done thats how easy and fun its is to make this little guy

its very bright and very handy too

on each 9v battery it will give you around 4 to 5 hrs of battery life and thats huge

Are you pushing full 9V to all LEDS in parallel?
I am afraid thats going to destroy them very soon.

Try 3 in series for VF of about 9v, and then parallel the string.

I have tested these and they work fine but again thanks for your advice

Its probably the very low mA from battery that is keeping LEDs alive.

These Leds have a forward voltage of 3 to 3.5V, you could put at least two of them in serie with a resistor. Actually, you lose more than 70% of the battery energy in pure heat. Leds don't like this, neither batteries do.

thanks bro for telling be about this
