Was looking through a drawer for something the other day and dug up and old combination flashlight lantern. The old silver and blue one, like in this stock photo. Well, I have had it for years. Used it camping a few times and a few times during power outages. I realized I still had the original batteries inside. So I figure I would leave it running and burn through the old batteries and put rechargeables in it to lessen the risk of corrosion. 72 straight hours later. And with fresh enerloops. So here is the review. Man, it has long battery life. I read it was rated at 200 hours with three AAA. I believe it to be accurate. It is not the brightest light. In extended lamp mode, I gives a dim, but useful area light. In very dark, it is bright enough to do most things by. In the retracted flashlight mode, it has a useful range of maybe up to 20 feet. Here is a beam shot from about twelve feet. I couldn't find the lumen rating for it. But I read someone estimate 20-30 lumens. I do not think that is accurate. Compared with my Fenix, I would guess it to beat around four lumens, especially with that run time. It gave about the same lighting as the Fenix on low (4 lumens). The Fenix on medium (27 lumens) totally blew it away. I think the Fenix is way more versatile, being able to throw out up to 100 lumens on one AAA. And even if you carry three AAAs and the Fenix, you would only get 84 continuous hours with battery changes. So maybe for the ultralight group that don't need really bright, it would work great. I think you might be able to squeeze out a month of usage on one set of batteries. For me, I don't mind carrying a flashlight with very good throw and a headlamp for utility. That was probably why this lamplight was in the back of a drawer.
