We replaced this light string unit. Used it because it did give off nice 'warm' light.
Anyway, it was an outside thing, eating enormous amounts of power of course, and we had it wrapped around nice hot heating pipes.. Guess what. This happends. We knew it, so just didn't leave it on when nobody was around, but it still needed fixing. So we did today.
There isn't too much space, so options are limited. We went for a.. not-too-pretty one from the IKEA. At least it wasn't killingly espensive :P
