Addresses concerns that arise in the field regarding the use of plastic tube guards on T-8 fluorescent lamps operated on high frequency electronic ballasts. Such guards are configured as “add-on” solid plastic sleeves that are held in place around the lamp via separable plastic end caps. These products maintain an air space between the outer lamp bulb wall and the inside of the sleeve when it is in place around the lamp. It is extremely important that the tube guards are properly installed utilizing these end caps. Improperly installed guards may come in direct contact with the bulb wall and problems may result. Installation instructions supplied by tube guard manufacturers must be followed. (April, 2000)
