the previous reviewer say that these be the same as Sears - they be not ! the Sears one be make by Dorcy and do not have the same shock tolerance as the dewalt bulb . I know - I be sucker into the Sears bulb and kill all of they -lrb- 4 -rrb- where I normally can go a long time with the Dewalt . they regularly tolerate shock from the flashlight tipping . the sear one blow everytime ! maybe I get a bad batch , but Ill never buy the Sears one again !
