Default Re: Old torches - anyone here collect them?

The second picture above is very like an Ever Ready I’ve got. This has a 1289 battery that I’ve re-stuffed with U12s.

It is also fitted with a 1W LED. Before anybody asks there is no current limiting resistor. I decided to see what would happen without — they are so cheap that blowing one up in the name or Research and Development isn’t worth thinking about. I must have done it five years ago and it’s still working.

My thinking was that the battery voltage won’t stay at 4.5V for long and it’s only lit for short periods. While I had it to bits to photograph I measured the current and it was 180mA, against the rated 300mA, and dropping as I looked. Even at that I wouldn’t want to look directly at it. It could even be argued that it’s “authentic” as incandescent torch bulbs were made to be bright at the cost of a shorter life.
