Desk lamp FAQ
Quick answers about brightness, color, bulbs, and placement.
Brightness
It depends on distance and task. As a reference, a 60 W incandescent equals about 800 lumens. Choose a lamp that can get bright enough to read print easily, and dim it down when you need less.
Lux measures how much light lands on a surface. Lumens measure what the lamp puts out. The same lamp gives more lux the closer it is.
Color
It is color temperature. Lower is warmer, higher is cooler.
How accurately the light shows colors, up to 100. Aim for 80 or more, 90 or more for color work.
Bulbs
Match the base and stay at or below the lamp's maximum rated wattage.
LED desk lamps are widely used for everyday work. Follow the manufacturer's instructions, and avoid looking straight into bright LEDs.
Placement
Opposite your writing hand.
Aim the lamp at the desk, not the screen, and move it until reflections disappear.
Health
Good lighting can make work more comfortable. Ongoing eye discomfort is a reason to see an eye care professional.
General information, not medical advice. See an eye care professional about eye strain or vision concerns.
