Floor lamps do provide some safety concerns. The heavy tops are susceptible to toppling over, causing damage to the lamp and possibly its surroundings. Additionally, most torchiere lamps use halogen bulbs, which become extremely hot while in use.
Floor lamps (downward lighting) and torchieres (upward lighting) are both effective in their own specific tasks. Torchieres are more effective in situations which require soft lighting, such as watching tv and simply lighting a room.
