Appropriate floor lamps and light in general is important in the whole house; however, the kitchen, in which lots of accidents can happen, must be lighted very well. You can never have enough lights in a multifunctional room.
The best solutions are flexibel enough for all practical tasks, but also can create a very nice atmosphere for eating and providing food. Several floor lamps and soft background light for the ambiente should cover all that. Floor lamps can also light working places. Their white light ensures colour and light like it is in nature, which is important, if you prepare a meal, observe the painting hours of your children or want to read in a cooking book.
Think twice where you work the most and plan in that way your lights. Light the whole table for your family with a floor lamp. If somebody wants to work and has to watch well, it must be very light.
Also in the living-room you need good, light and pretty lamps to install TV units and deep-pile rugs properly. Key safes might be necessary.
