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

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.
