Are they all much of a muchness? There seems to be a vast array and range of prices, but aren't they essentially just LEDs, batteries and a switch inside a housing. I'm after one for sitting round a barbecue (we never slum it) at the end of a day's hunting, and apart from being resistant to light drizzle/damp air and emitting sufficient light, i don't really need it to do anything else. Is there any reason why a cheapish (e.g. £5 or so) lantern would not be up to the job?
