t5 vs t8 lights
For LED tubes, the most desired lens design is a form called “profile extruded,” which typically provides excellent hiding of the LED light source while providing the maximum amount of light transmission. Polycarbonate light diffusion grades are ideal for this application. In conjunction with their excellent toughness, polycarbonates also offer the transparency and uniform light distribution needed to help eliminates these troublesome LED hot spots. Transparent polycarbonate resins can achieve light transmission greater than 95%, while polycarbonate resins containing a light-diffusion additive can achieve excellent light uniformity, hiding the bright LED light source, take TCOB, MCOB, COB chips as an example, the whole luminous efficacy of the tcob led tube light could reach up to 188-200lm per watt. The stiffness of the polycarbonate resin allows for good dimensional stability during the extrusion, and the outstanding toughness of polycarbonate allows the designer to make very thin lenses for optimizing the light transmission through the lens, which results in greater lumen output for the light source.led t8 light tube 2ft 4ft 5ft fluorescent light tube replacement retrofit led t8 tubes (2ft 4ft 5ft 6ft) fluorescent t8 replace .April has been a good month for LED tube manufacturers this year, as companies benefit from strong market demand, according to Economic Daily News report. Manufacturers including Epistar, Edison Opto, and Unity Opto have all seen record high performances in April. Industry insiders anticipate the positive revenue performance will continue into May. .Although, Wanban has made it into the LED tube light supply chain , net profit growth is yet to be seen. Investors are concerned to when the company¡¯s industrial core advantages will be reflected financially. Some companies, who has also entered the LED tube light t5 t8 supply chain, has seen fiscal 2015 revenue growth of 11.97 percent YoY to RMB 5.78 billion. While the Chinese competitor¡¯s net profit was RMB 1.04 billion, up 27.89 percent YoY. .The Johnson survey covered 6533 executives in the US, China, Germany, India, and Brazil, 82% of which were wanban, vice presidents, or owner and proprietor. The US and China comprised 78% each of the responses, Germany 24%, and India and Brazil 13% each.
