Whether LED tube technology has entered the second stage and mature enough that can be commercialized, no one can give out a satisfied answer at this moment. There is also no LED Panel Light company that has done a complete 10,000-hour aging test. Many LED manufacturers have very limited knowledge about their products. Large brand LED fluorescent tubes usually have one-year warranty. The warranty of domestic LED fluorescent tubes varies according to the quality of products, from 1 year to 3 years. Currently, domestic LED interior lighting industry is under an unordered development. Lacking of cleared uniform standards, it is predicted that the price battle of LED lighting products will be continued for a very long time.
What are the differences between normal fluorescent tubes and LED fluorescent tubes? LED tube lights have higher quality, more durable and can save more energy, have wide options in beam angle, higher light efficiency (the brightness of a 15W LED Tube is equivalent to the brightness of a 40W fluorescent tube), can work in high temperatures, with anti-moisture/water-proof/leak-proof function. The commonly used covers for LED tubes are Glass cover and PC (Poly Carbonate) cover. LED tube lights use the most advanced lighting technology – LED, with digital appearance desighs, saving up to 70% energy. The service life of LED tubes is nearly 10 times longer than ordinary fluorescent tubes, almost maintenance-free.
LED tubes use green semiconductors as light source, very environmental friendly, soft rays, pure spectrum, providing more protection for human eyes and health. The 6000K Cool White light source gives a cool feeling to our eyes, which will make people be easier to concentrate and improve their working efficiency.
Currently, compared with traditional fluorescent tubes, LED fluorescent tubes have following advantages: 1) save more energy; 2) long lifetime; 3) Good applicability, since the small size of LED chips, they can be made in various shape; 4) short response time (several nanoseconds); the response time of fluorescent tubes is around several milliseconds; 5) environmental protection, no health-hazard metal waste, easy for recycling; 6) emit multiple pure colors (narrow spectral range, via combinations of red/green/blue rays). Disadvantages: 1) expensive; 2) great gap between theoretically light efficiency and practical light efficiency; 3) great gap between theoretically lifetime and practical lifetime; 4) the heat dissipation problem; However, all these defects can be improved by more advanced LED technology.
