LED light lasts 1 year turned on

Hanover Fist · Dec 26, 2014

I read some where of a keychain light that stays lit for a year on a single battery charge. Not sure the battery size and the LED was dim but usable in the dark, e.g., finding keyholes etc. Does anyone recall something like this?

I remember about a decade ago PALights were somewhat popular and they used a 9V battery and glowed very dimly for a long time (up to a year or so).

Not really keychain-sized and the dim glow wasn't that usable but it was easy to spot in the dark.

Calipsoii's lamplighter project?

My PAL lights run well over a year on 9V batteries that have already spent a year in smoke detectors.

I have one in my Bathroom as a nightlight and it has been running since last year about this time too!

I am afraid though it looks like the company has bit the dust?

Crazy lights!

Wow, impressive.
I have to admit I never really used my PALight that often.

I'm tempted to go dig it up now but I'm not quite sure where it is...

I hope the family wants to keep the company running. The PALights are unique, and I have found them very useful.

Thanks everyone! Pak-lites? Since palights arent available?

2 AA eneloops driving a 5mm LED will last at least a year. Cheapest route that involves a premade host is to use a harbor freight 2AA incandescent flashlight as a host and stick the 5mm led into the bipin socket. You will have to drill the reflector. You can use a minmag as a host, but you still have to drill or remove the reflector.
