Until the advent of advanced LED lamps, flourescent lamps were unsurpassed in terms of efficiency and lighting comfort. The lamp's quick restart, good light stability even on conventional, magnetic gear, and reasonably simple wiring made them easy to service although the lamp bi-pin connection was prone to failure due to lamp's handling as well as normal wear, the system was reasonably easy to repair and failures were quite obvious. | |||
TL5 lamps are more of a specialty product as they were not highly popular. Some large retailers and office building administrator used them in most installations, however, typical office, residential, commercial and especially industrial premises remained on standard TL-D or T8 lamps fixtures even as late as 2008. This was especially due to cost but also due to the the inconvenience of retraining employees to install and maintain efficiently a different lamp technology. There was also the issue of maintaining incompatible inventory for another separate installation that was not a very major improvement compared with the switch from TL to TL-D lamps or from standard TL-D lamps to TL-D Super 80. All these were major reasons for avoiding newer TL5 installations unless ultimate efficiency and no cost concern were goals at that specific time. | TL5 lamps are more of a specialty product as they were not highly popular.

TL5 Super 80 lamps, even if they were not called that way they were still comparable to TL-D Super 80 lamps, were advantageous due to high luminous output and low price. The wide array of colour temperatures caters to any application. Warm colours or more active daylight ambiances can be created easily. The lamps' very good stability and output ensures a long service life with minimal degradation. This was especially important compared with TL-D Standard lamps, as the older lamp type aged much quicker and had lower light output along with colour reproduction. Requirements for higher than 80 Ra colour rendering index in Europe made the lamps extremely popular and even made them as cheap or even cheaper than TL-D standard lamps due to volumes, marketing and economies of scale. On the other side, if TL-D Super 80 lamps were already retrofit or retrofitable on an existing installation, there was little justification for new TL5 lamps. Even presently, prospects for retrofits are still good, with LED tubes being able to replace older flourescent lamps on TL-D or T8 installations.

Even presently, prospects for retrofits are still good, with LED tubes being able to replace older flourescent lamps on TL-D or T8 installations. Cost-wise, TL5 lamps were most advantageous when compared with the prospect of replacing magnetic or inductive ballast TL-D or T8 lamps, as TL5 lamp type already mandated high frequency electronic lamp gears which bring much increased energy efficiency and comfort. | ||
