“LED torchlight are pretty common these days, but if you happen to have an incandescent filament light bulb based on 100 years old technology, here’s your chance to have it updated with LED that last 8000 years! (if incandescent has a human lifespan)
Take a regular PR 2 bulb with a P13.5s base (i.e. those most commonly in torchlight), reuse the base and insert 3 x 5mm diameter white LEDs. See image of end result below.
The shortcut to this project is to go into a shop and buy one of these. But hey, what’s the fun in that when you can make your own!” – Link.
