Once the lamp was constructed (quite easily), I screwed in bulb as per instructions but the lamp wouldn't light. When I unplugged the lamp and tried to unscrew the bulb, the bulb separated in my hand (see photo). I then had to unscrew the base of the light bulb from the lamp using a kitchen knife as it seemed stuck. Dangerous and now I need to buy a new bulb. Hopefully same thing won't happen.
