Mr Light

Good range of lights but with a permanent revolving sale — so basically everything is at double price and you should only buy something if it has been significantly reduced.
I read the review on the Fulham Road branch and apparently there’s an owner called Carlos who wanders over from this branch from time to time. I suppose I’ve only visited the King’s Road branch when Carlos has not been there as I’ve only ever encountered a surly youth who is extremely unfriendly and most certainly does not throw in a bulb — quite the opposite as he tries to sell you the bulb for three or four times the price of Peter Jones at Sloane Square.
In short, good range of modern lights but all heavily overpriced before reductions.
