I have have two Mini Maglite LED 's now , the first be package as a 3 watt , but no explanation of lumen . it have only two mode , on and off . I think it be a great light , but after about a year of daily use , I start have problem with the switch sticking . I spray a small amount of wd40 into the barrel to loosen the switch . it work , and I use it for several more month trouble free , until it start stick again . I repeat the wd40 trick , and the switch again start work , but this time , the light output turn blue . it look like there be some kind of a clear cap over the led that come off , apparently loosen by the wd40 . I be unable to reattach it , so I retire that light as useless , and purchase a new one . the new light have the additional mode , and say nothing about 3 watt , but it be every bit as bright as the original . I add the petroleum jelly around the thread , and it work great for a few week . then I start have trouble with the switch . I think the petroleum jelly would have take care of that , but it do not . I finally dip a q-tip in wd40 , and very carefully apply a very small amount around the switch . so far so good . I buy one for my wife , she light exhibit the same problem . it be always with the switch .
