Desk Lamps and LED Task Lamps

Brightness, color and flicker at the work surface

Task lamps should be judged by lumens, color temperature and how steady the light is, not by wattage. A small 2.5 W lamp rated about 220 lumens suits a quick read, while desk work and detail tasks are more comfortable with more output. Dimming and several color temperatures let you move from warm in the evening to a neutral white by day. Flicker-free drivers and a high color rendering index make long sessions easier on the eyes.

Base, clamp or clip: where the lamp sits

A weighted base is simplest but takes desk space, a clamp attaches to a desk edge and frees the surface, and a clip-on lamp grips a shelf or monitor frame. Check the opening of the clamp or clip against the thickness of your desk. A two-segment arm gives more reach and a gooseneck holds any position, but check that the joints keep their position under the lamp's weight. Cord length, USB or mains power and a built-in charging port matter at a shared desk. Some listings are cords or sensors rather than lamps, so read the title.

Questions about Desk Lamps and LED Task Lamps

How bright should a desk lamp be?

For reading and writing, a lamp output of roughly 450 to 800 lumens is comfortable, and detailed work such as soldering or sewing benefits from more. Choose a lamp with adjustable brightness so you can match it to the task and the room light.

Where should I place a desk lamp?

Put it on the side opposite your writing hand, a little ahead of you, so your hand does not cast a shadow. Keep the bulb below eye level to avoid glare, and angle the light onto the work surface, not the screen.

Which suits a small desk, a clamp or a base?

A clamp suits a small or crowded desk because it takes no surface space, as long as the desk edge is thick enough and free of a lip or overhang. A base is easier to move between rooms and needs no fixing, but uses desk space.
