The TL or T12 lamps can be considered the most durable in physical terms although the TL-D lamps have the longest lifespan with the best performance out of this lamp selection, due to their gas fill and electrode design. TL mini lamps fare very poorly in terms of lifespan as well as performance. Note that using an electronic ballast for TL Mini lamps does not offer a significant improvement as most are not of high quality, especially in easy to find luminaires. Starting the lamp with cold cathodes and not operating them properly can be just as bad as a classic magnetic ballast. | |||
The best service life can be achieved using electronic gear that has preheat. Note that TL and TL-D lamps are perfectly interchangeable on their gears as the TL-D lamp was purposefully designed to operate at reduced current on the same conventional ballast as the TL lamps. | |||
Due to their construction, flourescent lamps cannot be trully repaired. However, if one of the end electrodes remain open due to the coil's sudden rupture as a result of a shock or any other damage, and the lamp does not have strong blackening, it can be repaired. Bridging the broken fillament lamp ends on the side that has been measured as noncontinuous with an ohmmeter, using a wire strip and soldering or careful tightening, can render the lamp operable again. However, note that the lamp is more dangerous to operate as the magnetic or electronic gear used with the lamp is stressed more to start the lamp. Some warm start electronic ballasts may be damaged if one of the lamp's end are shorted, so there is some risk involved. Lamp gears may be overheating when attempting to start the lamp for a long time, so if this occurs, consider the lamp as disposable. | |||
