Advantages

(1)Environmentally friendly: no pollution, no UV, no infrared and no heat radiation;

(2)Low energy consumption design, 150 hours of power consumption is only one degree, the desk lamp in the case of providing sufficient lighting, the smaller the power the better; using semiconductor technology to produce a light source has a very high photoelectric conversion efficiency, so that the electricity you provide, can be maximized into light;

(3) Long-life light source, 10 years without changing the bulb, 100 times more than ordinary light bulbs;

(4) The light source does not contain tungsten, mercury and other toxic heavy metals. Semiconductor light source does not have incandescent tungsten filament nor fluorescent lamps, energy-saving lamps inside the mercury;

(5) Safety. 12V low voltage DC power supply; no easily broken glass parts to ensure the safety of users. 36V is the smallest voltage that the human body can feel, less than 36V power supply is safe for the human body. It doesn't even need 3C certification. DC power supply, eliminating the electromagnetic radiation pollution of high-frequency AC power.

Disadvantages

(1) High blue light intensity, blue light hazard, eyes are extremely vulnerable;

(2) Monochromatic light source, the color spectrum is too narrow, the optic nerve of the eyes will have an impact, easy to fatigue;

(3) LED small light beads, the use of a few years will slowly wear and tear and can not be replaced, which can easily cause the entire desk lamp scrapped;

(4) The color temperature is basically 5000K or more, pure white is very bright, more blinding;

(5) Poorly made LED eye lamps will produce a slight strobe and radiation.
