We designed an illumination improvement scheme for a jewelry store located in the famous gold street in Dubai in 2012. The jewelry store had high requirements on luminous flux so that the owner had to replace the fluorescent lights once every 3 months as the brightness of fluorescent lights attenuates quickly. We recommended our integrated T5 LED lights to the store. These lights are able to work for 5 years with high fluorescent flux, and can save large amounts of labor and material cost for the customer. The customer was quite satisfied with our products and planned to replace all the lights in the 15 branch stores with our integrated T5 LED lights.
