Wasn't sure what to call this thread. Please Register or Log in to view the hidden image! Basically, I first noticed this effect, if it is indeed for real, after buying a cheap little reading lamp at a thrift store that was powered by 3 AA batteries. The batteries were brand new when I put them in. It worked perfectly, and had a decent brightness for the little bulb. Just one of those portable reading lights, more or less. The bulb itself is only a few millimeters across, and probably a few watts as well. Anyhow, in the first week I had it, I tried it out basically, and it saw no more than between twenty and thirty minutes approximately of use. It was running at the same constant brightness/luminosity/what-have-you. About a week or two later, I turned it on again, and noticed that it was definitely dimmer than it had been before. I thought that was pretty strange. Didn't use it for another week still. When I did turn it on, it was a dull orange color, and then after a few seconds, the output cut quite dramatically, and it was barely giving off light. It was basically the filament glowing dimly, and it was definitely useless for any practical light output. So, to sum it up, we have good solid output at the same level for the first week and only about a half-hour of use. After about two weeks of non-use, it has become dimmer by about 50%. Only ran it for a minute or so during that period. Another week later, and it is practically dead. Seems to me that the batteries were definitely losing power to SOMETHING during that time, and it wasn't the lightbulb! My uncle is an electrical engineer, and he didn't seem to think that the batteries would just drain like that, but I'm really not sure, because they went really dim in a short time without any use. Is anyone familiar with this kind of thing? Is there some flaw in the circuit which would drain the batteries regardless of whether power is flowing to the lightbulbs or not. I mean, my portable cd player lasts longer than that on less batteries (I think it takes a single AA)!
