We are going to take a long run time flashlight (65 hours) and turn it into a longer run time flashlight (Update:  The title of this Instructable says 3.6x run time but actual run time ended up being over 360 hours).

Yes it is another long run time flashlight hack. This one is easier than my other one. All you need a resistor, a soldering iron and this flashlight.

This Eveready flashlight (model number 5109LSH7 or 5109LS) costs $4.97 at Lowes:

(This is a great long run time flashlight to have even if you don’t do the modification.)

I just picked up another one at my local Lowes. I like this flashlight because as is it has a long run time before the battery needs to be replaced (65 hours). It is bright. It is cheap and it is easy to hack. You can do this hack in 10 or 15 minutes and most of that time will be waiting for your soldering iron to heat up.
