I personally do not have one of these -lrb- although I have use other people 's -rrb- but have a lead 3d maglite . it make no sense to pay $ 20 for a antique incandescent 3d maglite when you can get a lead version right here on amazon for only $ 25 ! the led be brighter , around 10 time as energy efficient and have no filament to break from impact or turn it on and off a lot . the only reason to buy this old light be if you want to use it as a heater !  mag-lite st3d016 3-d cell lead flashlight , black
