Doulex, abbreviated as "Doule" in Chinese, is a brand that emerged in 2009 and specializes in LED creative products. It has successfully launched a series of green, environmentally friendly and energy-saving LEDs on the market, and sold well on Taobao. The LED mouse light to be discussed today is Doulex's latest work. Its lovely shape resembles an egg. Its special feature is that it has two gears of switch: one is normal mode, the other is breathing mode. Under the breathing mode, the light has the same frequency with people's breathing, flickering between bright and dim, so it is also known as the breathing light. This mouse light comes in five colors: white, pink, orange, green and yellow-green. I received the yellow one.
