Of tubes is said to be good, and some say good leds, which is really good
I'm not professional, I think the lamp that shield an eye is a concept. It doesn't matter. Conditional or get a LED, more fashionable. A long service life, the power supply is not bad, can be used for the rest of your life. Strong, not easy broken. Finally is integrated packaging, light emitting area is relatively larger, and no more light of shadow.
Tell you a data, under 30 cm of height, the desk lamp of illumination can reach 1180 lux this data is the most the desk lamp that shield an eye, fluorescent lamp or LED. Also have no who is the eyes of the lamp to read a book, so the LED light dazzling is not a problem
Incandescent lamp is red light, yellow light is refers to the 2700 k color temperature, most provinces to eyes, fluorescent tubes and LED light is dazzling.
Tricolor fluorescent light color soft, should be good for the eye eyesight protection. The advantage of leds is save electricity, but light is dazzling. As a desk lamp, there are a dozen of lamp is ok, wattage is too big, is not good for your eyes.
