A major advantage of T8 and TL-D lamps, regardless of type, is their full compatibility with systems of similar power ratings that were used with T12 lamps along with full replacement capability of any lamp type at a specific wattage. This makes it possible to test and replace many lamps of a specific wattage even mix lamps in multi-lamp fixtures to create a desired effect. Compatibility of T12 and T8 lamps was very important in the past as new T8 lamps were more efficient and used less power while being fully capable to be retrofitted on old installations. | A major advantage of T8 and TL-D lamps, regardless of type, is their full compatibility with systems of similar power ratings that were used with T12 lamps along with full replacement capability of any lamp type at a specific wattage.

Closed as well as open fixtures are very well suited for any lamp type. In general, open fixtures are better suited for lamps operating in warmer indoor environments while enclosed fixtures are better suited for colder environments. Despite what any datasheet may suggest, deviating higher or lower than the set 30-35 degrees Celsius lamp temperature slightly reduces efficiency. Super 80 lamps are the least affected by temperature changes as only the internal UV radiation can be influenced. | TL mini lamps and especially TL Mini Super 80 lamps are highly useful as showcase light, due to their small size and preference for hotter operation, so a compact display case or fixture does not affect their output and is generally preferred. | ||

TL, TL-D and TL Mini lamps are more sensitive to additional light losses due to internal coating's temperature variation than TL Mini Super 80. | |||
