Flourescent lamps are the most popular and widely used lighting source. Still widely used in most indoor environments due to their high efficiency and very good colour reproduction, flourescent lamp stocks and availability is still high. Millions of these lamps have been produced worldwide for decades. They are clearly suited for indoor lighting especially when paired with an electronic ballast that eliminates flicker and also increases system efficiency. Due to the great variety of lamps, there are some suggestions for use. Most flourescent lamps operate well at 25 degrees Celsius ambient temperature | Flourescent lamps are the most popular and widely used lighting source.

Most flourescent lamps operate well at 25 degrees Celsius ambient temperature but have very low light output in freezing or below freezing environments but hot environments also reduce efficiency. | ||
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.
