If space is an issue on your desk, then the last thing you want is a bulky lamp taking up space. Clip-on desk lamps are the solution for your office. Instead of sitting on the desk, this lamp comes with a spring-hinged pressure clip that firmly holds the lamp in place at the edge of your desk. While clip lamps do hold tightly when placed on a desk, they are not meant for homes with children who may attempt to pull the lamp loose.
For an individual who prefers to change the level of light at her desk or needs to constantly adjust it for different areas of the desk, an adjustable-neck lamp is an excellent option. This style of desk lamp is fitted with a weighted base so that it sits firmly on the desk's surface. The neck is fitted with multiple hinges or even a telescoping spine to allow for exceptional flexibility.
This unmoving lamp is meant more for aesthetic appeal than actual use, although you can select a sufficient wattage for the lamp to provide lighting. The lamp itself is completely stationary and meant to sit on the back center of a traditional office desk. This lamp is not meant for computer desks, as the computer's screen will entirely block the lamp's light.
For a busy home with curious pets or young children, the safest place for lamps is mounted on the walls or ceiling. This is especially true of an office area where children are already drawn to computers and printers. Wall mounted lamps have a base that is mounted with screws directly into the wall with either drywall supports or into a stud. These lamps will typically have a flexible or hinged neck to allow freedom of movement with the lamp.
