So, I’ve printed a model of the batman signal searchlight from the films, for a couple of people at work. I’m looking to put a light in it to make it work. I’ve experimented with some LEDs I had here, wired up to a usb cable plugged in to a phone charger plug, but they’re not bright enough, only really any good as a nightlight for a child. I then tried a 12v twin led that I’d fitted in the boot of my car, but it’s still not really bright enough, and then has the added problem of finding a 12v power supply to go with them.
So has anyone here got any suggestions for a high light output, on a low voltage?
Requirements are:
As bright as possible,
Preferably 5v as I believe that is the output of a phone charger/pc usb socket
Must not create too much heat, item is 3D printed plastic so will start having issues if the light gets hot
If it has to be higher 5v, ie 12v or similar, I’d need a recommendation for a cost effective power supply to go with it
Needs to be a single point of light, either 1 LED, or 1 bulb, or multiple LEDs but with a lens to focus the light, otherwise the shadow doesn’t work.
Any suggestions are gratefully received, I do have more options on their way, but don’t have much hope for them after today’s trials.
