I be seek a AA Maglite flashlight and notice the `` lead upgrade '' offerer by a number of vendor . I find this flashlight and decide to buy it because it be the genuine maglite brand and feature the lead bulb . the lamp be much brighter and the light be much whiter without the dark spot typical of the standard maglite bulb . what be disappointing be that its larger than the standard size aa maglite , and the larger size feel strange in the hand . I wind up buy the standard aa maglite and the nite-ize led upgrade .
