reading about the Polish Tipi on here made me unpack the one I'd got on ebay months ago but never got out (for a variety of irrelevant reasons!). Must try it in the garden next week - at least I've buttoned it up so far! However, noting the comments about how dark these are got me to thinking about the UCO mini-candles - I've seen them in the various ads and similar style ones in the USA, but never used one. How effective are they? I like the KISS principle of them (and size), but do they actually provide decent light, or is the 9-hour one a more sensible one? I'm fed up with battery-driven ones, and wouldn't have a paraffin one in a tent.
