States E27 standard bulb, but arrives requiring a small golf bulb. I bought this for the sole reason that it takes an E27 bulb. This takes a golf bulb, which are becoming increasingly rare to find, and are much smaller, they also don't put out as much light. I now have to work in semi-dark, buy something else, throw this away, and wait up for the postman for it to arrive (I work night shifts, so it's a hassle). Complete waste of time and money.
