Introduction: Tactical Flashlight for Just $10.50

Needless to say, my inspiration for this project was Kipkay's video on the same subject. Here is a brief description of what I had to do to achieve the same results.

Step 1: Gather All of Your Materials.

The first thing you need to do is gather all the parts you need. For this instructable, you will need 1 Eveready Industrial Flashlight, found at Home Depot for $3.97. You will also need 1 6V flashlight bulb from Radioshack; model KPR112. This is about $1.50. Finally, you will need 3 123 batteries. These can be found on surefire.com for about 2 dollars a piece. Total cost for this project is slightly over $10.50.

Step 2: How to Modify the Flashlight.

First, you need to unscrew the end cap end the lens cap. Inside you will notice two spines running the length of the light and another two with a strip of metal between them. All you need to do is remove one of the spines that is not next to the metal. To do this I used a chisel from a generic X-ACTO type kit. After this, I taped the 3 123 batteries together so they would be easier to insert and remove. Then I inserted the batteries. It is a very tight fit. It will require some pushing. A tight it fit is better because it prevents the batteries from rattling and from excessive shaking. Replace the standard bulb with the KPR112. Screw both ends together and you should have a working tactical style flashlight.

If you look at the first image below, at 135 degrees there is no spine

Step 3: The Final Product.

I bought two flashlights just in case I "accidently" messed up one of the flashlights. I decided to paint the flashlight black, just like Kipkay, but I had it set on a piece of cardboard on my back lawn. Lets just say "the wind" blew the flashlight down and grass got stuck to the wet paint. This was the perfect time for a test. I had to wash the grass off the flashlight, but I used Krylon and it stuck pretty well. I decided to submerge the flashlight and impressively, the flash light still turned on after I pulled it out of the water. I was left with a very ugly black paint job.
See below.
Because of this incident, I decided to modify the second flashlight and make an Instructable about it. Now the yellow flashlight has the good batteries and bulb and the ugly brownish yellowish blackish camoflaguish one is stock.

Test results are on the following page.

Step 4: Test Results.

There really is no comparison. It must be seen in person to be truly appreciated. Here are the pictures. These shots are taken about 1 foot from a white wall. The first two pictures are the two evereadys compared. The stock one gives off a brownish tint while the upgrade gives off white light. Pictures 3 and 4 are front shots of the two evereadys. Pictures 5 and up are the Eveready mod next to the Dorcy K2 6 Watt Luxeon, the brightest Luxeon L.E.D. on the market. It puts out 120 lumens. This is a $40 flashlight. Thank you for viewing and "happy modding."
