like several of the reviewer here , I have difficulty find replacement bulb for my Makita BL185 flashlight . these work perfectly . they be just as bright , or perhaps a bit brighter , than the original . -lrb- it be hard to tell because I have be in the dark for a bit ! -rrb- they be also MUCH cheaper than they counterpart at Home Depot or Lowe 's . I have a prime account ; so I pay no shipping , and they arrive in a day and a half . some reviewer mention heat related problem . my flashlight come with xenon bulb originally and get pretty hot . these be no different . my original bulb last many year , and I expect these will , as well . just be sure to use common handling practice and do not touch the bulb with you finger . if you experience be like mine , you 'll be happy about this choice .
