I recently received the last light I am going to buy for a while, a Lumintop Tool in basic black with the Nichia emitter. Last night I decided to throw a cell into it and compare it to one of my other Tools. I inadvertently grabbed a 10440 instead of a regular AAA and dropped it in. As soon as I saw how bright it was I realized my mistake and took it out again. I then dropped in one of my NiMH AAA cells. To my surprise, I found out that if I switched the Tool on completely, it wouldn't light up except for a single flash. But if I only partially pressed the switch, it would work. I thought it might be the cell, since it been sitting around for a while, so I checked it with my ZTS, and it showed 50%. Should work still but who knows. Then dropped in a lithium primary, same results. My last choice was the last alkaline AAA cell I own, and nothing. Nada. Closer inspection revealed that the tail cap was only screwing down about half way. When I looked into the tailcap, the spring and internal mechanism seemed closer to the end then they were before. There is some sort of ring with two opposing slots in the tail cap. I took a small screwdriver and tried rotating that ring clockwise. Wonder of Wonders, the whole unit started moving back up into the tail cap. When I had rotated it as far as it would go, I tested it again. Worked just fine, with any one of my three different types of AAA cells. Just thought I would pass this along in case anyone else runs into this problem. Other than that, the Tool is a nice little light. I have three or four now (black with Nichia, black with Cree, and one or two Copper with Nichia [I'm not sure right now]} and these will be my last light purchases for hopefully a long while. We'll see how well my will power holds up.
