Cool.

Cool idea but keep in mind that the KPR112 is rated for 6 volts and 15 - 20 hours life.

Powering it at 9 volts will probably shorten it's life considerably and run pretty hot.

It's still worht having some fun with.

So solder in a resister like with LED's
I recommend not holding the casing while drilling.(vise please)

If you add resistance it will decrease current and brightness.

Besides that the bulb is only 8 ohms.

Do the math.

No reason to as I have enough to worry about.
I was doing all types of home made light creations back in the eighties.

E over I x R is your friend.Just chant with me....OOOOOhm.

I'm an engineer and a tech.

You will not find a small value resistor that will fit in the case an do what you want it to.

can't wait to try it!

Not hold the Case you want to spoil all the fun.
How about only two batteries and an a piece of Copper pipe with a cap,
6 volts bulb not as bright and normal. life

Explains lack of imagination as there are creative ways to do things Mike

Go for it.

Explain to me your creative way of defying physical laws.

Here is your big chance Bob.

Bigger case, or electrical tape mike.
What thats beyond laws of physics?
Also you could focus (yuck, yuck) on frenzel lens or the reflector

You said adding a resistor would work.

Explain it if you can with detail. Use math if you have to

What started out as a $10 flashlight has now evolved into a fire-starter, emergency road side flasher and stun gun. Too complicated for me and you guys managed to suck all the joy juice out of this one.

Sorry Doug.

I just get tired of bs information being posted.

This is still a good idea as long as you don't think it will last like a real flashlight.

Do you want to rely on a flashlight that may burn out at anytime while you are in a crawl space or attic?
