We bought 11 strings of 2m LED white icicles. I have to say when they are working, they look stunning, but don't expect them to last any longer than the lights available for a fraction of the price available from discount stores nowadays. Mine lasted 2 years, meaning we had around 5-6 weeks total usage before they dimmed drastically. The reason we spent £300+ was to avoid getting the ladder out over christmas to change them, it didn't happen. Yes, the cables are heavier than the lights you buy in discount stores, yes, they are brighter, but they don't last & I certainly wouldn't advise leaving them up all year if they can't take he weather over the Christmas period. We were disappointed & have yet to find lights which can actually stand up to the British weather. I would imagine they would be fine if used indoors, but that wasn't why we bought hem in the first place. Sure, cheaper lights need replaced, but I'd rather replace a 20 quid set from B&M bargains than a £300 set from lights for fun. Think before buying!
