1. What is Lumen (Lm)?

The lumen (Im) is a unit of luminous flux in the international system of units, that is equal to the amount of light given out through a solid angle by a source of one-candela intensity radiating equally in all directions. It is
the real measurement of brightness provided by a LED light bulb.

Color temperature is a description of the warmth or coolness of a light source.
Higher color temperatures (4000K-6500K) are considered cool while lower color temperatures (2700K-3000K) are considered warm.

3. How many Lumens should a desk lamp have?

How many lumens you want from your bulb depends on the purpose of the lamp. For a lamp with a particular task, you'll want more lumens. For example, for a reading light, you'll probably want at least 450 lumens.

4. ls an LED lamp better than an incandescent lamp for desk use?

Yes. 90% of the energy used for an incandescent produces heat not light. A dedicated LED desk lamp is a better choice for quality of light and for more effective use of the LED. Another benefit for people who work close to a desk lamp, a lot less heat on your face.
