Introduction: 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.
