Some of you probably know me as a knife knut and gun gnut, but I'm only a neophyte flashlight fnut and this is my first post here.
I picked up a Dorcy 1led few days ago. After I played with it a little I put a fresh Everready Gold in it and turned it on to see how long it would run. After 7 hours I couldn't stay awake any longer, and it was just as bright as when I started to my eyeball gauge. I compared it to a minimag from time to time as a check, shining them both against a white wall, and I couldn't detect any dimming.
The next night I turned it on again and after 1 1/2 hours (8 1/2 total, but not continuous) I noticed it was getting dimmer. At 9 1/2 hours it was barely glowing at all, about the level of an Indiglo watch (ie bright enough to find a keyhole at a range of a few inches). I turned it off for 5 minutes, turned it on and it was at full brightness again, for a while. I compared it to the minimag again, and it looked just as bright as when the battery was fresh. I also tried swapping in a fresh Everready Gold and couldn't see any difference. I swapped the test battery back in and it dimmed pretty rapidly after that and died completely at about 12 1/2 hours.
