Dear Friend, New rounds of power rationing have been initiated in Zhongshan GD regions, the entire Anhui province and the whole Zhejiang province. The rationing in Guangdong and Anhui was due to tight electricity supply, while that in Zhejiang was resulted from the "dual control system" upgrade for energy consumption. If you have any preparation order, please arrange it ASAP to avoid delivery delay in peak season . Black Friday : High Bay light * 110LM/W * 3 Years Warranty * Triac Dimmable Only 11.95USD Stable quality, stable delivery time as well as best price. Best Regards Emily
