The light source of the desk lamp could not be seen. To achieve the eye protection effect, the desk lamp needs to be equipped with a lens, a grille, etc. to prevent direct light from forming glare, and the bulb exposure is absolutely impossible.

High color rendering and suitable color temperature, color rendering should be greater than 80%, and the color temperature of the table lamp is 3300K-5300K. Pay attention to the signs on the fluorescent tube when buying: rr is daylight color, rn is warm white, these two colors can play the role of eye protection; while rl is cold white, rb is white, no eye protection.
