How many watts should be used to protect the eye desk lamp?
The 5000K tube is closer to the eye light at noon, and the color temperature of natural sunlight is good for your eyes.
If the color temperature is too high, the light source is bright and white, which is no different from the ordinary fluorescent lamp. It is better to buy 4000K, 4500K and 5000K.
Not necessarily depends on the number of watts to buy the lamp, but also to see the color temperature of the tube. The general choice of 13W, 18W enough, too bright will be more dazzling, but the color temperature is still the most critical.
