is it possible to add regulation to the lightwave 3000 (7 led's on 3 c cells, if so how is this modification done, i have not purchased this product yet, so i dont even know if there is room inside the flashlight for any kind of board. this light is going to be stored down in the storm shelter i dug in the crawl space under the house. i plan on putting lithium cells in it for longevity. this light is rated fairly good for output duration, but i would like to see that output more stable during the life of the cells. of coarse anything can be modified (i hope).
