I just bought a cheap Muyan 9 LED light. I know I get what I pay for, but seeing Craig's and Doug's review; small, functional, cheap, comes with three free cheap AAAs, why not?
I thought 5mm LEDs were never strong enough to interfere with most electronics, but funny thing is, this light did.
The TV was on (the model is the last of the sony Trinitrons before they were finally discontinued) and as I placed the cells in and started to screw the tailcap, I noticed that the TV flickered. I continued to screw the tailcap and the TV flicked again. Each time I turned the tailcap, the TV would flicker. I decided to go crazy and twist it back and forth just to be sure, and yep, as long as the tailcap continued to be turned, the TV would flicker. Weird. This might have something to do with the following.
I was getting bored with the interference experiment so I went on to test the light. It seemed to light up only when it want to. I noticed in the reviews that the anodizing went all the way to the threads, thus not making good contact, which is true with this sample. I did not feel like scrubbing off the anodizing, so I left it and did something else. What I noticed about the switch was that I could not tell whether it was on or not, as most clickies have an "up" or "down" position that this one does not. Ten minutes later, I came back to try the light again. Whoa! It was hot! I immediately removed the tailcap to release the case containing the cells so they don't continue to cook. The cheap Panasonic AAAs were too hot to touch! Had I came back any later, they might have exploded.
Even if it is not producing light, it appears that a high amount of current would still run though it, enough to heat it up. Maybe that might also explain the TV interference, but whatever it was, crisis adverted. To the reject pile it goes.
