The main function of clear safety sleeves is the protection from glass contamination through breakages, but they also protect the lamp from minor impacts.
The clear safety sleeves are perfect for the food industry. The main areas of application for the clear safety sleeves are in agriculture, food and drink preparation and manufacture, food and drink display and storage. The sleeves can be used in fridges and chiller cabinets; and the polycarbonate cover keeps the fluorescent lamp warmer and therefore increase the light output.
