TL Mini lamps use an obsolete design that results in very poor performance. There are only very few cases where such a lighting source was satisfactory due to their short life of around 5000 hours, quick lumen depreciation due to blackening at the tube's ends and phosphorus decay due to the lamp operation. This technology can be considered a bridge between T8 and T5 lamps but nothing else. In general, except if the light source is desirable for reference or a specific effect, these lamps should be avoided. | TL Mini lamps use an obsolete design that results in very poor performance.

Although these lamps have poor performance compared with their T8 counterparts due to the obsolete lamp gas filling that uses argon instead of krypton, their efficiency and colour reproduction is improved compared with standard TL Mini lamps. These lamps can be used on their own as accent or ambient lighting in small areas, due to their size. | ||
TL lamps are the classic T12 flourescent light source that has been used for almost 80 years. Obsolete by 2000s standards, the lamp still survived in situations where performance in cold environments such as outdoor ones was appreciated as well as ones where the lamp's relative size resulted in less glare than T8 lamps. The lamp's performance was simply average as lamp end blackening is noticeable and the internal lamp coating does not have very good performance. Note that flicker is more visible than in T8 lamps. Overall, these lamps have been plentiful but they are somewhat scarcer today. They can be used where a diffuse light source is desirable. Although there were more advanced lamps that had Triphosphor coatings and better colour rendering, they were rare and the T12 54 or 765 type was a popular, standard, daylight flourescent lamp, widely used worldwide. It creates a good retro atmosphere when used in classic luminaires. | TL lamps are the classic T12 flourescent light source that has been used for almost 80 years.
