LED Mirror
I bought a tape of LEDs thinking that I would convert the lighting in my study to LED, but the tape was shorter than the perimeter of the room, and the LED intensity was too low for it to be useful as a ceiling light (note to self: make sure to buy the super-bright variety next time). After a quick look around I found a new use for the tape – an LED mirror (aka zit-popping mirror 🙂 It was perfect – the perimeter of the mirror was 5m more or less exactly, as was the length of my tape.
