"What is the difference between the LED lamp with energy-saving lamp?" Composition in different ways: LED lamp by the highly efficient light-emitting diodes; structure and fluorescent tube energy-saving lamp of the same, but the fluorescence powder inside the tube is high efficient rare earth element material. "Each of which is better?" Advantages and disadvantages of contrast, LED lamp: life is very long, more electric energy can be saved, the disadvantage is the high power LED tube light price is very expensive; energy saving lamp: low price, save electric energy, the disadvantage is the short life. "Which is more suitable for home lighting?" The applicable scope of different, objectively speaking, energy saving lamp tube has been widespread, home use is preferred, but pay attention to buy brand-name manufacturers of products, long service life; the LED lamp power larger currently more expensive. "LED lamp used as a desk lamp, a long time will make the eye fatigue?" The factors causing the fatigue of the eyes are mainly two: first, the lamp "strobe"; II, "illumination lamp". LED lamp is DC drive, does not exist the stroboscopic problem, used as a desk lamp should be very good. On illumination (i.e. brightness), can be adjusted at any time. Energy saving effect is big different, 10WLED fluorescent lamp brightness than conventional 40W fluorescent lamp will light, 16WLED fluorescent light than traditional 64W fluorescent lamp will light, LED fluorescent lamp brightness especially softer people more easily access granted. The service life of -8 million in the 50000 hours of power supply voltage AC85V-260V (AC), without qihuiqi and ballast, start fast, small power, no stroboscopic, not easy to visual fatigue. It is not only more environmentally friendly energy superpower. Is one of the key development of national green energy saving lighting engineering products, is the main product to replace the traditional fluorescent lamp.
