I bought a battery powered strip of LEDs from Primark this afternoon. This was only two quid so it's not the end of the world if I destroy it during my tinkering, but I thought I'd ask here if anyone has any experience in tinkering with similar strips.
Basically what I want to do is fix them to the bottom of a pedalboard, ideally powering them from the pedalboard power supply. The lights work with 3 × AA batteries, so nominally 4.5V.
Two questions I'd like answered if anyone has experience are:
1. Is a 9v PSU likely to work, or kill the unit?
2. If I can't work out the polarity of the two wires and identify this using a trial & error methodology would getting it wrong first time be likely to kill the unit?
