Someone said to 7 w is enough light It does not hurt the eyes But I go to TB, some sellers told me 3 w is enough (equivalent to an incandescent bulb 40 w) don't know that right?? ...... Would like to ask how many watts of LED desk lamp what you buy is good for your eyes? What color temperature in right? Thank you ~
LED desk lamp, sure enough, under 3 w is divided into warm light color temperature below 4500, more than 5500-6000600 is white light don't choose the color is not straight slant blue, warm red light is yellow, like the light bulb.
3 w, 7 w will be stabbed eyes, desk lamp advice or use energy-saving light downier, in general, color temperature of 2700-3100 is suitable, is the warm light and natural light, white light 6400 of real life, we still use more but look for a long time, eyes will sting.
In general, the bright LED lights, the brightness of the 1 watt equivalent to 20 watts incandescent lamp, therefore, used as a table lamp at close range, 3 watt LED lamp brightness should be sufficient. About the color temperature, personally think that as long as you feel comfortable, but the color temperature is too high may feel dazzling, easily tired... Might as well choose between 3500 ~ 6000 ° K.
