Noob Q: Mag 2AA Conversion

I have a few Mag 2AA flashlights. Not being able to go back to incad after being exposed to Luxeon, my options are either to dispose of/gift them or convert them. (I like their focusing feature.)

I know that this sounds like a very elementary Q to many of you but I have no idea where to go. So what is the cheapest way to convert these and BTW I cannot even recall how to access the batteries. Is it from the head part or does the tail screw open? I recall it was the tail but I cannot unscrew the tail (too tight) and do not want to damage the body by using pliers. Any help?

The tail screws open. You can use a mouse pad or rubber tubing for cushion along with pliers to get the tail cap open if it is too tight.

I think the cheapest option for conversion is the niteize led drop in. A little bit brighter. I've seen them at walmart. I think the best led conversion is the TerraLUX TLE-5EX. I have one. It is very floody.

If you want to make the light brightest possible take a look at the AuroraLite hotwire kit. But it is kind of expensive.
