Fascinated by these fatboy edison lights – you charge them and then pull the tag and they glow for up to 6 hours. I love how simple they are, and how flexible they can be (I can imagine using them in lots of places). Best of all I noticed that design public has them with an offer of 2 for 1 at the moment. Buy one, get one free (this is not an affiliate link, just me passing on something I think is pretty cool). I bought some so will let you know how well they work when they arrive. (The offer only lasts until the end of the month).
