GZ International Lighting Fair is fully a success for we LEDSTAR. Products highlighted and attracted a lot of customers,especially 170Lm/W glass led tube. No company has such high lumens led tube with true test report. This fair found that5yrs warranty or longer warranty period will definitely be a trend in the future. People also get a preference to one compann'sprofessionalism,which is the reason for us to talk happily and actively with most of the customers.
