12W moisture proof wall lampwarranty for 3 years

1. The led energy-saving lamp has the same stroboscopic phenomenon as the ordinary incandescent lamp under the AC drive, while the ordinary energy-saving lamp has no stroboscopic phenomenon. Strobe makes the eyes easy to fatigue (now LEDs are driven by DC, so they don't exist

Strobe phenomenon

2, the light of each led bulb is too bright, it will strongly irritate the eyes, can not be directly looked at, even for a short time, and the ordinary energy-saving lamps are relatively softer! (Research and invention of LED is the best lighting tool for modern eyes, basically no harm to the eyes)

3, the illumination angle is limited, generally only 120 °, and ordinary energy-saving lamps can be irradiated 360 ° (you do not have much use of 360-degree lighting, just waste electricity, now LED fluorescent lamps are very mature)

4. The brightness of the illuminated room is not better than the energy-saving lamp, because the LED has high brightness only in the narrow angle of direct view, and the light is rapidly weakened after deviating from the angle. (Now the brightness of LED is basically more than 30% than the energy-saving lamp. The brightness of the basic 20W fluorescent lamp is comparable to the 40W energy-saving lamp)
